1 Introduction

1.1 Intended useSample gas pumps are intended for installation in gas analysis systems for industrial applications.

DANGER Danger of explosion if used in a potentially explosive atmosphere

Sample gas pumps of types P2.3C and P2.4C are not suitable for use in potentially explos-ive atmospheres and must not be placed in them.

The complete designation of the P2.3C and P2.4C sample gas pumps is:

II 3G/- c IIB T4 X

The P2.3 C and P2.4C sample gas pumps may only be used to convey explosion class IIA and IIB flammable gaseous media whichare not explosive during normal operation, as well as non-flammable gaseous media.

The maximum surface temperature varies by the medium and ambient temperatures. Please refer to the data sheets for thecorrelation between media temperature, ambient temperature and the pump’s temperature class. Flammable mediums mustnot be heated beyond these values. Please note, flammable gas must only be heated up to 80 % of its ignition temperature. Thelower of the two values is the maximum medium temperature.

Gas sampling is generally prohibited if the gas flow results in a dangerous electrostatic charge in the bellow / pump body (alsosee chapter "Operation and Control").

The sample gas pumps are only intended to convey gaseous media. They are not suitable for liquids.

Please note the additional information in chapter "Product Description" and "Operation and Control" along with the informa-tion on specific intended use, existing material combinations, as well as pressure and temperature limits in the data sheets.

When installed outdoors, ensure adequate protection from the weather, see chapter Requirements for the set-up location [>page 10]

2.2 General hazard warningsInstallation into a complete system can pose new hazards on which the manufacturer of this sample gas pump has no bearing.If necessary, perform a risk assessment of the complete system this product will be installed into.

When configuring and building the complete system the relevant national safety regulations for the installation site and thegenerally applicable state of the art must be observed. These can be determined through applicable harmonised standards,among other things, e.g. IEC 60079-14. Additional national regulations pertaining to initial operation, operation, maintenance,repairs and disposal must be observed.

When conveying flammable gasses, avoid potential exothermic reactions in your system, do not use materials with a catalyticeffect in the conveyor lines. Dangerous rises in temperature could result. Sample gas pump materials in contact with media arelisted in this operating manual to facilitate the safety assessment.

Adiabatic compression is part of the physical operating principle of bellows pumps. Dangerous rises in temperature cannot beruled out with improper exceeding of the operating parameters. Conveying flammable gasses then pose an explosion hazard.

Avoid these dangerous circumstances. If necessary, the complete system should be secured against flashback. Follow these no-tices and the applicable national regulations, prevent malfunctions to avoid personal injury and property damage.

The operator of the system must ensure:– The equipment is only installed by a professional familiar with the safety requirements and risks,

P2.3C P2.4C

3 Transport and storageThe products should be transported only in its original packaging or a suitable replacement.

When not in use, protect the equipment against moisture and heat. Keep it in a covered, dry and dust-free room at a temperat-ure of -20 °C to +40 °C (-4 °F to 104 °F).

Outdoor storage is forbidden. As a matter of principle, the operator must regard all applicable standards according preventionof damage due to lightning, which may otherwise damage the sample gas pump.

The storage room must not be equipped with any ozone-producing devices like fluorescent light sources, mercury arc lamps,electric high voltage devices.

Before restarting the pump after long-term storage or an extended standstill period, the insulation resistance of the windingphase-to-phase and phase-to-ground must be measured. Moist windings could cause leakage current and flash-over. The insu-lation resistance of the stator windings must be at least 1.5 MΩ, measured at a winding temperature of 20 °C (68 °F). For lowervalues, drying the winding is required.

The motor shaft should be rotated in regular intervals to ensure sufficient lubrication of the bearings in long term.

To do this, unscrew the three cross-head screws of the housing cover and remove the cover (see fig. 1, fig. 2). The crankshaft isnow visible.

CAUTION Contusion hazard

Contusion of the fingersDon’t have your fingers caught between eccenter and slide.

4 Installation and connectionCheck the equipment for damage before installation. Among other things, this could be a damaged housing, supply cables, etc..Never use equipment with obvious damage.

CAUTION Use appropriate tools

According to DIN EN 1127-1, the operator is responsible to select and use appropriatetools.

4.1 Requirements for the set-up location

CAUTION Equipment damage

Protect the equipment, particularly gas connections and gas lines, from dust, falling ob-jects, as well as external blows.LightningOn principle, the operator must meet all applicable standards with respect to preventingdamage to the equipment due to lightning, which could result in equipment damage.

CAUTION Avoid vibrations and resonances

The operator is responsible to mount the pump in a way that vibrations and resonancedo not cause premature failure resulting in creating an effective ignition source.

The ventilation must be unobstructed and the exhaust air – and from the adjacent units as well – must not be directly re-siphoned.

The motor is rated for ambient temperatures between -20°C and +50°C and for installation altitudes ≤ 1000 m above sea level.

If installed without the mounting bracket, there must be sufficient spacing between the motor and the rear wall. The further en-vironmental parameters for the set-up location can be found in the data sheet at the end of the operating and installation in-structions.

P2.3C P2.4C

4.1.1 Outdoor installationThe sample gas pumps were not specifically designed for outdoor setup. The operating and environmental conditions are cru-cial for the required types of protection and any additional measures required, such as:

– adequate protection from the weather

– Adjusting the maintenance intervals (e.g. cleaning and replacing wear parts)

Use suitable measures and regular inspections to prevent damage to the equipment from e.g.:

– Corrosion

– Sunlight (temperature peaks and damage from UV rays)

– Moisture from condensation (e.g. due to rapid temperature changes or downtimes)

– Icing

– Insects and microbes

– other animals, e.g. martens, etc.

Please remember that all technical operating parameters of the equipment must also be met with outdoor installation. Specific-ally:

– Maximum or minimum operating temperatures

– Degree of protection

4.2 Installation

CAUTION Damage to the device

Protect the device, especially the gas inlets and tubes, against dust, falling parts and ex-ternal impact.

P2.3CDuring the installation of the P2.3C sample gas pump onto mounting plates, use the supplied mounting bracket and exclusivelythe supplied rubber-metal buffer. Operation without the rubber-metal buffer is forbidden. They must also be used if the pumpis installed on an existing supporting structure. The hole pattern of the mounting bracket and the motor base can be found inthe data sheets at the end of the operating and installation instructions.

P2.4CFor the installation of the P2.4C sample gas pump, please consult the 42/011-14-3 assembly drawing. The sample gas pumpshould be checked for its completeness before beginning installation. 6 x M6 screws with nuts of the appropriate length are alsorequired for the installation.

For all pump types, the pump head can be oriented exclusively at an angle of 0° or of 180°.

4.3 Special condition moist sample gasApplications where the sample gas is still moist may result in condensate forming in line and the pump body. In these eventsthe pump head must be suspended (pump body facing down).

If the pump was not ordered this way, it can easily be converted on site.

Install the line between the gas output and condensate drain with a grade so the condensate can drain and does not collect in-side the pump or the lines.


P2.3C P2.4C

4.3.1 Alteration of hanging pump bodies

CAUTION Damage to the device

Especially with pump head pointing down, make sure that no dust or small parts can in-trude the pump through the ventilations slot. Nevertheless, the slot must not be covereddirectly. If this is not possible, the pump must not be mounted with pump head pointingdownward.

To perform this, unscrew the three Phillips head screws of the casing cover (Figure 3, Figure 4) and remove the cover (also see thespare parts drawing at the end of the operating instructions). The crankshaft drive and the engine flange will now be visible. Thepump housing is fixed to the engine flange and/or the intermediate flange (depending on the pump type) with four hexagonbolts (SW8). Unscrew these completely (Figure 5). When unscrewing the last screw, hold the housing tight. Now carefully rotatethe housing on the centring of the flange by 180°, screw it tight again (Figure 6, Figure 7) and then re-install the cover (tighten-ing torque of the hexagonal bolts 3Nm). Offsetting the installation of the pump head by 45° is not permitted!

P2.3C P2.4C

4.4 Connecting the gas tubesThe pumps are delivered with customized gas connections. Please compare the part-no. on the type plate with the part-no. ex-plained in chapter "Introduction".

Avoid mixed installations, that is connecting metal tubes to plastic bodies. If this is unavoidable for sporadic applications, screwthe metal fitting with utmost care and without any use of force to the PTFE pump body.

Install the tubes in a way that the line at the inlet and outlet is flexible over a sufficient distance (pump vibrates).

The pumps are marked with “In” for inlet (input) and “Out” for outlet (output). Make sure that the connections to the tubes aretight.

4.4.1 Monitoring the sample gas pump

NOTICE

When following preventive maintenance according to the maintenance plan, a crack inthe bellows is a rare malfunction, but cannot be completely eliminated.

NOTICE

If the bellow cracked, turn the pump off immediately!

NOTICE

If flammable gases (even above upper explosion limit (UEL)) or toxic gases are supplied,continuous monitoring of the pump is mandatory.

DANGER Explosion hazard, danger of poisoning!

A crack in the bellows when conveying flammable or poisonous gasses may allow explos-ive or poisonous gas mixtures to leak or develop.Monitor the pump with a flow- and/or vacuum monitoring system (see flow diagram).If a pump defect occurs, shut it off immediately.

4.4.1.1 General monitoring measuresSince a crack in the bellow allows the ambient atmosphere to be sucked in and the sample gas pump continues to generatepressure, the bellows of the sample gas pumps must be inspected regularly.

In addition, the flow rate of the pump (to the sample gas outlet) must be monitored with a suitable flow meter.

For more information or Inspecting the bellow the maintenance schedule, please refer to the chapter Maintenance at the end ofthe operating and installation instructions.

4.4.1.2 Monitoring measures when conveying flammable and/or toxic gassesConveying flammable and/or toxic gasses further requires continuous monitoring of the sample gas pump during operation.This can be done as follows (1) or (2).

1. Flow rate monitor before the pump’s gas inlet or after the gas outlet. A sudden reduction of the suction volume / flowvolume ahead of the pump and consistent or suddenly increased flow volume after the pump indicates a defective bellow(the pump can convey ambient air suctioned in due to the tear).

2. Vacuum monitoring before the pump’s gas inlet and flow monitoring after the gas outlet (see illustration). A sudden dropin the vacuum before the gas inlet indicates a defective bellow.

When conveying flammable gasses above the upper explosive limit (UEL) we further recommend monitoring the lower explosivelimit (LEL) in the installation location.

When conveying toxic gasses we recommend MAC monitoring (MAC: Maximum Workplace Concentration) at the installationsite.

WARNING Hazardous electrical voltage

The device must be installed by trained staff only.

CAUTION Wrong mains voltage

Wrong mains voltage may damage the device.Regard the correct mains voltage as given on the type plate.

For the sample gas pump, a switch and a circuit breaker (in accordance with the authorisation) is to be provided. This must beorganised to be easily accessible for the operator. The switch must be labelled as an isolating device for the unit. It must not beinserted into a mains power line or interrupt the protective conductor. Furthermore, the switch must separate the sample gaspump from the live parts for all the poles.

The sample gas pump must be secured against unacceptable excessive warming by using a suitable overload protection (motorprotection circuit breaker).

Observe the rated current for the setting of the circuit breaker (see the motor identification plate).

Attach the pump in accordance with the circuit diagram on the terminal box housing cover and ensure that the strain relief forthe connection line is sufficient. When doing this, ensure that the pump motor has the correct voltage and frequency (voltagetolerance ± 5 % and frequency tolerance ± 2%).

The supply line and earthing cross sections must be adapted to the rated current.

Use at least a wire cross-section of 1.5mm2.

Connect the circuit breaker of the motor to the local protective conductor.

Connect the protective conductor in accordance with DIN VDE 0100 without fail to the marked protective conductor terminal.

There must be no foreign objects, dirt or humidity in the terminal box. Close unneeded cable inlet openings and seal the box it-self against water and dust. Use the original seal when closing the terminal box.

Unused openings must be closed with approved stoppers.

Observe without fail any different information on the identification plate. The conditions at the operation site must correspondto all the ratings plate information.

5 Operation and control

NOTICE

The device must not be operated beyond its specifications.







DANGER Adiabatic compression (explosion hazard)!

In case of adiabatic compression, high gas temperatures may occur. The operator is re-sponsible to consider this situation.Make sure to obey the allowed technical specifications and ambient conditions, take spe-cial attention to the media temperature with respect to temperature class T4. These varyin addition to gas composition and ambient conditions. Where necessary, the operatormust install temperature sensors for monitoring and must automatically shut down thesample gas pump should the temperature exceed the limits.

DANGER Dangerous electro-static charge (danger of explosion)

During the pumping of, for instance, very dry gases or gases contaminated with particu-late matter, potentially incendiary electro-static charges could build up in the bellow /pump body.Provide the pump with a particle filtration with a suitable filter unit placed before thepump gas inlet.The extraction of explosive gaseous media (max. zone 2) with the pumps is not permit-ted if the gas flow leads to a potentially incendiary electro-static charge in the bellow /pump body (projected surface area in bellow / pump body ~ 15 cm2).


Flammable media fed into the pump may only be heated to a maximum of 80 % of theirrespective ignition temperature.

CAUTION Hot surface

– no parts of the sample gas pump have been dismantled (e.g. cover),

– the gas inlet and outlet of the sample gas pump is not shut,

– the preliminary pressure is under 0.5 bar,

– in the event of throttling under 150 l/h in continuous operation, a bypass is available,

– the ambient parameters are complied with,

– information on rating plates is observed,

– the voltage and frequency of the motor correspond to those of the network,

– the electrical connections are tightly fastened and the monitoring devices have been connected and configured correctly!

– air inlet openings and cooling surfaces are clean,

– protective measures have been carried out; earthing!

– the motor is secured correctly,

– the terminal box cover is closed and the cable entry points have been properly sealed,

– the elastomer sprocket of the coupling (P2.4C only) is correctly installed and undamaged,

– depending on the operating mode, the necessary protective and monitoring devices are present and functional (dependingon the type of pump, e.g. motor circuit breaker, manometer, flame arrestor, temperature monitoring).

When switching the sample gas pump on make sure that– no abnormal sounds or vibrations occur.

– the flow rate is neither too low nor too high. This would indicate a cracked bellow.

5.2 Operating the sample gas pumpThe sample gas pump is intended exclusively for the pumping of gaseous media. It is not suitable for liquids.

The sample gas pump should be operated without pre-compression. A preliminary pressure of more than 0.5 bar is not permit-ted. The gas outlet must not be shut.

The sample gas pump should be operated without pre-compression. A preliminary pressure of more than 0.5 bar is not permit-ted. The gas outlet must not be shut. The flow rate must be at least 50 l/h. In the event of throttling under 150 l/h in continuousoperation, the flow rate must be regulated via a bypass. In this case you should choose a version with bypass valve.

NOTICE

Extreme throttling reduces the life time of the bellow.

For pumps with an integrated bypass valve, the output power can be adjusted. Do not expend a great amount of power whenturning the valve as otherwise the valve could be damaged! The turning range of the valve is around seven rotations.

NOTE: Read and observe the maintenance plan!

b) Make sure that the equipment cannot be reconnected to mains unintentionally.

c) The device must be opened by trained staff only.

d) Regard correct mains voltage.

CAUTION Tilting risk

Damage of the deviceSecure the device against any sudden translocation during maintenance.

CAUTION Gas leakage

The sample gas pump should not be dismantled under pressure.







DANGER Explosion hazard due to incorrect replacement of components

The replacement of the components requires carefulness. Inexpert operation could leadto explosion.If you feel uncertain about any details of the operation, please bear in mind that the re-placement should be done by the manufacturer only.


P2.3C P2.4C

CAUTION Hot surface


Depending on the quality of the sample gas to be pumped, the valves in the inlet and the outlet may have to be changed fromtime to time.

If the valves are heavily contaminated, in particular after just a short period of operation, then you should provide for particlefiltration before the pump. This will increase the service life considerably.

6.1 Maintenance plan

Component Interval Work to be carried out To be carried out byScrews of the pump body After 500 h Tighten the screws to 3 Nm CustomerEntire pump Every 500 h Inspect hose connections, protective and control

6.2 Inspecting the bellow

NOTICE

When following preventive maintenance according to the maintenance plan, a crack inthe bellows is a rare malfunction, but cannot be completely eliminated.

NOTICE

If the bellow cracked, turn the pump off immediately!

NOTICE

If flammable gases (even above upper explosion limit (UEL)) or toxic gases are supplied,continuous monitoring of the pump is mandatory.

DANGER Explosion hazard, danger of poisoning!

A crack in the bellows when conveying flammable or poisonous gasses may allow explos-ive or poisonous gas mixtures to leak or develop.Monitor the pump with a flow- and/or vacuum monitoring system (see flow diagram).If a pump defect occurs, shut it off immediately.


P2.3C P2.4C

Since a crack in the bellow allows the ambient atmosphere to be sucked in and the sample gas pump continues to generatepressure, the bellow on the sample gas pump must be inspected regularly.

This is done by connecting a suitable shut-off unit and a suitable vacuum pressure gauge ahead of the sample gas input (see il-lustration). If during operation, after closing the suction line, no negative pressure is produced, the bellows is defective andmust be replaced.

Please refer to the Maintenance schedule for maintenance intervals.

Important noteThe tables headed "Chemical resistance of plastics" and "Properties of plastics materials" have been compiled from informationfrom various producers of raw materials. The figures relate exclusively to laboratory tests on raw materials. Plastics items madefrom these materials are often subject to influences which cannot be detected in a laboratory test (temperature, pressure,stresses in the material, chemical substances, design features, etc.). For these reasons the figures quoted can serve only as aguideline. In case of doubt we strongly recommend that a test be carried out. No legal claims can be derived from these figuresand we disclaim all liability. The chemical and mechanical resistance of a product does not suffice for the assessment of its suit-ability for use, for example legislation on flammable liquids (explosion protection) is to be taken into particular consideration.
