1. Introduction

IntroductionThis data booklet deals with Grundfos SEG and SEG AUTOADAPT sewage grinder pumps.

Fig. 1 SEG and SEG AUTOADAPT pumps

The SEG pumps are designed with a grinder system which grinds solids into small pieces so that they can be led away through discharge pipes of a relatively small diameter.

The pumps are made of wear-resistant materials, such as cast iron and stainless steel. These materials ensure reliable operation.

The pumps are available with motors of 2.0 hp and up to 5.5 hp. All motors are 2-pole motors.

The nominal diameter of the pump discharge port is 1 1/2" (40 mm) or 2" (50 mm).

The pumps are available for

• submerged installation on auto-coupling systems• submerged installation, free-standing.

ApplicationsThe SEG pumps are ideal for use in sparsely populated areas where gravity sewage systems are not available. Examples include small villages, farm areas, and areas with difficult topography, such as rocky terrains with large differences in levels, or any other area where a pressurised system offers advantages.

Construction featuresAll pumps have the following features:

• Cable connection to motor via plug.• Watertight cable entry of corrosion-resistant

stainless steel with polyamide.

• Clamp connection between motor and pump.• Cartridge shaft seal.• Heavy-duty bearings greased for life.• Patented grinder system ensures extremely high

efficiency and reliable operation.

• SmartTrim system enables quick and easy impeller clearance adjustment in order to maintain peak performance.

• Thermal switches built into the motor windings provide protection against overheating.

Additional SEG AUTOADAPT featuresThe SEG AUTOADAPT pumps incorporate a controller, sensors and motor protection. They only need to be connected to the mains supply.

The pumps offer the following benefits:

• Built-in level sensor, which also calibrates to actual atmosphere pressure.

• Dry-running sensors.• Built-in motor protection (thermal switches).• Pump alternation.

If several pumps are installed in the same tank, the control logic incorporated in the pump will ensure that the load is distributed evenly among the pumps over time.

• Alarm relay output.The pump incorporates an alarm relay output. NC and NO are available and can be used as required, for example for acoustic or visual alarms.

• Random start delay in case of general power shutdown.

• The pump does not start unless the phase sequence is correct.

• Self-calibration after each pump cycle.• Anti-seizing function.

The anti-seizing function starts the pump at programmed intervals to prevent the impeller from seizing up. This function will overrule the dry-running sensor of CSA-approved versions.

• After-run function (foam draining).The after-run function can be used at programmed intervals if there is a risk of a floating layer.

• Test run.It will be possible to test that the pump can start, even if the pump is dry. By default the pump will operate for 2 sec.

• Latest motor power.The latest consumed motor power consumption will be recorded.

• Restart limitation.Through configuration it can be selected if the pump should have a maximum number of restart attempts after a failure.By default the feature is disabled, meaning that the pump will always attempt restart after failure.

• Maximum operation time.The pump can operate for maximum 10 minutes. If the liquid level is at or above the start level, the pump will automatically start again.

The Grundfos CIU unit can be permanently or temporarily connected for changing the default settings, making further settings or reading the log and operating parameters, such as number of starts and operating hours.The Gundfos PC tool can also be used for temporarily connection to change settings or reading the log.

Features

Ball bearings

The ball bearings are greased for life.

Top bearings:

• 2.0 hp (1.5 kW):Single-row ball bearing 6201.

• 3.0 hp (2.6 kW) and up:Single-row ball bearing 6205.

Bottom bearings:

• 2.0 hp (1.5 kW):Single-row ball bearing 6303.

• 3.0 hp (2.6 kW) and up:Angular-contact ball bearing 3205.

Shaft seal

The SEG range is available with two shaft seal variants. Both variants are fitted as cartridge seal units. The shaft seal separates the motor from the pumped liquid.2.0 hp (1.5 kW) pumps have a silicon carbide/silicon carbide (SiC/SiC) mechanical shaft seal as primary seal and a lip seal as secondary seal. In connection with service, the mechanical shaft seal and the lip seal are supplied as one unit ready for fitting.Pumps of 3.0 hp (2.6 kW) and up have a double mechanical seal with a cartridge consisting of a SiC/SiC mechanical shaft seal as primary seal and a carbon/aluminium oxide mechanical shaft seal as secondary seal.

Motor

The motor is a watertight, totally encapsulated motor.Insulation class: F [311 °F (155 °C)].Supply voltage tolerance: - 10 %/+ 6 %.Temperature class: F [221 °F (105 °C)].Enclosure class: IP68.Max starts pr. hour: 30.For motor protection and sensors, see the Sensors section.

Power supply cables

Standard cable

As standard, the cables are 33 feet (10 m) long. Other cable lengths are available on request. See List of variants section, page 12.The number and dimension of cables depend on the motor size.

Cable entry

The stainless-steel plug is fastened with a union nut. The nut and O-rings provide sealing against ingress of the liquid.The plug is filled with a two-component compound that is cast into the plug around the leads of the cable. This prevents the ingress of water into the motor through the cable in case of cable breakage or adverse handling in connection with installation or service.

Sensors

SEG

As standard, the pump has two thermal switches incorporated in the motor windings to protect the motor against overheating.

SEG AUTOADAPTAs standard, the pump incorporates the following:• One analog absolute-pressure transmitter.• One dry-running sensor.

Explosion-proof versions have two dry-running sensors.The dry-running sensor(s) are used for indicating the stop level in the first pump cycle and to prevent dry running.On standard versions, the dry-running sensor can be overruled by an optional CIU unit if there is a risk of a floating layer.

• All pumps have two sets of thermal switches incorporated in the stator windings to protect the motor against overheating.

• Two Pt1000 sensors for analog measurement.• Built-in motor protection I2 (t) as extra safety.

Operating conditionsThe pumps are designed for intermittent operation (S3). When completely submerged, the pumps can also operate continuously (S1).

Fig. 13 Operation levels

• S3, intermittent operation:The S3 is a series of identical duty cycles TC each a constant load for a period, followed by a rest period. Thermal equilibrium is not reached during the cycle. See fig. 14.

Fig. 14 S3 operation

• S1, continuous operation:In this operating mode, the pump can operate continuously without having to be stopped for cooling. See fig. 15. Being completely submerged, the pump is sufficiently cooled by the surrounding liquid. See fig. 13.

Fig. 15 S1 operation

Pumped liquidspH value: 4-10.

Liquid temperature: 32-104 °F(0-40 °C).

When pumping liquids with a density and/or a kinematic viscosity higher than that of water, use motors with correspondingly higher outputs.

For short periods (max. 3 minutes), temperatures up to 140 °F (60 °C) are permissible (non-Ex versions only).

Sound pressure level

The sound pressure level of the pump is lower than the limiting values stated in the EC Machinery Directive (2006/42/EC).

Motor range

Frequency converter operationThis section applies to SEG pumps only.

Note: The SEG AUTOADAPT pumps must not be used with a frequency converter.

In principle, all three-phase pumps, except the AUTOADAPT versions, can be connected to a frequency converter.

However, frequency converter operation will often expose the motor insulation system to a heavier load and cause the motor to be more noisy than usual due to eddy currents caused by voltage peaks.

In addition, large motors driven via a frequency converter will be loaded by bearing currents.

For more information, see the installation and operating instructions for the relevant frequency converter at www.grundfos.com (WebCAPS).

ApprovalsThe standard versions of SEG and SEG AUTOADAPT 60 Hz pumps have been approved by CSA.

Approval standards

These pumps are CSA-approved according to UL778 and C22.2 no. 108, no. 0.4, no. 30, no. 145 and no. 60529.

Curve conditionsThe guidelines below apply to the curves on pages 28 to 35.

• Tolerances according to HI 1.6 - 2000, acceptance level B.

• The curves show the pump performance with different impeller diameters at the rated speed.

• The curves apply to the pumping of airless water at a temperature of 68 °F (20 °C) and a kinematic viscosity of 1 mm2/s (1 cSt).

• The Eff (eta) curves show the efficiency of the pump for the different impeller diameters.

• In the case of other densities than 62.4 lb/ft3 (1000 kg/m3), the discharge pressure is proportional to the density.

• When pumping liquids with a density higher than 62.4 lb/ft3 (1000 kg/m3), motors with correspondingly higher outputs must be used.

Calculation of total head

The total pump head consists of the height difference between the measuring points + the differential head + the dynamic head.Htotal = Hgeo + Hstat + Hdyn

Performance testsThe requested duty point of every pump is tested according to HI 1.6 - 2000, acceptance level B, and without certification.In the case of pumps ordered on the basis of impeller diameter only (no requested duty point), the pump will be tested at a duty point which is 2/3 of the maximum flow of the published performance curve which is related to the ordered impeller diameter (according to HI 1.6 - 2000, acceptance level B).If the customer requires either more points on the curve to be checked or certain minimum performances or certificates, individual measurements must be made, and a certificate can be ordered.

CertificatesCertificates must be confirmed for every order and are available on request. See List of variants section, page 12.

Witness testIt is possible for the customer to witness the testing procedure according to HI 1.6 - 2000, acceptancelevel B.

The witness test is not a certificate and will not result in a written statement from Grundfos. The witness test itself is only a guarantee that everything is carried out as prescribed in the testing procedure.

If the customer wants to witness the test of the pump performance, this request must be stated on the order.

Hgeo: Height difference between measuring points.Hstat: Differential head across the pump.Hdyn: Calculated values based on the velocity of the

pumped liquid on the suction and discharge sides of the pump.

SEG pumps

Level controllers

Grundfos offers a wide range of pump controllers to keep a watchful eye on liquid levels in the wastewater collecting tank, ensuring correct operation and protection of the pumps.

Controller ranges:

• Dedicated Controls, DC• SLC and DLC level controllers• CUG 100 control box.The SLC and CUG 100 are designed for one-pump installations, DLC is designed for two-pump installations and DC can operate up to six pumps in the same pit.

Dedicated Controls

Grundfos Dedicated Controls is a control system that can control and monitor two to six Grundfos wastewater pumps and a mixer or a flush valve.Dedicated Controls are used in installations requiring advanced control and data communication.

Main components of the Dedicated Controls system:• CU 362 control unit• IO 351B module (general I/O module)• IO113• SM113.Dedicated Controls are available as separate components. The control system can be operated by the following:

• float switches• a level sensor• a level sensor and safety float switches.The separate control unit and modules can be built for practically any size of system.

Fig. 25 CU 362 control unit

The DC control can be fitted with various units:• The CU 362 control unit, which is the "brain" of the

Dedicated Controls system, is fitted in the cabinet front. The CU 362 can be fitted with one of the Grundfos CIM communication modules mentioned below, depending on the monitoring needs or the SCADA system:

– The CIM 202 is a communication module used for the Modbus RTU fieldbus protocol.

– The CIM 252 is a communication module used for GSM/GPRS communication. The CIM 252 establishes communication between the CU 362 and a SCADA system, thereby allowing the application to be monitored and controlled remotely. This module also offers SMS messaging, for example status and alarm messages.

– The CIM 272 is a communication module for the Grundfos Remote Management system (GRM). The CIM 272 establishes communication between the CU 362 and the GRM, thereby allowing the application to be monitored and controlled remotely.

– The CIM 050 GENIbus module is placed in a Grundfos product. The CIM 050 enables data transmission between a GENIbus network and a Grundfos product.

– The CIM 500 is a communication module between an industrial Ethernet network and a Grundfos product. The CIM 500 communicates with the CIU 902.

• The IO 351B module, which is a general I/O module. The IO 351B communicates with the CU 362 via GENIbus.

• The MP 204 motor protector (optional), which provides many electrical status values, for example voltage, current, power, insulation resistance and energy. The MP 204 offers better protection of the pumps than a conventional motor protection device.

• The CUE/VFD (optional), which is either a Grundfos variable-frequency converter or a general variable-frequency converter, also offers better pump protection and a more steady flow through the pit pipes, so the pumps are treated well and the energy consumption is kept at a minimum.

For further information, see the data booklet or installation and operating instructions for Dedicated Controls at www.Grundfos.com (WebCAPS).

SLC and DLC

Features and benefits

Control of one pump (SLC) or two pumps (DLC).• Automatic alternating operation of two pumps

(DLC).• Automatic test run (prevents shaft seals from

becoming jammed in the event of long periods of inactivity).

• Water hammer protection.• Starting delay after power supply failure.• Automatic alarm resetting, if required.• Automatic restarting, if required.• Alarm outputs as NO and NC.

Fig. 26 DLC and SLC controllers

When an SMS module (optional) is fitted in an SLC or DLC controller, it acts as a time recorder for the pumps, and when programmed (using an ordinary mobile phone with text messaging facility), it can send text messages containing "high-level alarm", "general alarm", information about operation and the number of times the pump has started. The SMS module is also available with battery and can thus send text messages that will inform you of power failure and when the power has been restored.

For further information, see the data booklet or installation and operating instructions for the SLC and DLC controllers at www.Grundfos.com (WebCAPS).

CUG 100

The CUG 100 control box is designed for the starting, operation and protection of small wastewater pumps.

The control box is available in several variants which can be used for the following:

• single-phase pumps (230 V up to and including 7 A)• three-phase pumps (460 V up to and including 4 A)• three-phase pumps (575 V up to and including 3 A)• three-phase pumps (200-230 V up to and including

7 A)and

• start/stop by means of a float switch• manual start/stop.During manual operation, the pump is started and stopped with the on/off switch.During automatic operation, the float switch will start and stop the pump.

For further information, see the installation and operating instructions for the CUG 100 at www.Grundfos.com (WebCAPS).

SEG AUTOADAPT pumps

Grundfos CIU unit

The Grundfos CIU unit (Communication Interface Unit) is used as a communication interface between a Grundfos product and a main network.

The CIU unit is used as an interface for the following:

• Configuration of pump parameters required for water level control.

• Online monitoring of pit and pump values.• Manual water level control (forced start/stop).• Obtaining of measured and logged data that is

valuable for pump service and pit optimisation.

The CIU unit is designed for use together with Grundfos SEG AUTOADAPT pumps. Communication can be established with the Grundfos GO remote control or by using the main network interface of the CIU unit.

Available CIU units:

• CIU 902 unit (without CIM module)• CIU 202 Modbus unit• CIU 252 GSM/GPRS unit• CIU 272 GRM unit (Grundfos Remote

Management).

The CIU unit incorporates one or two modules:

• Multi-purpose IO module with I/O functionality, IR communication interface and powerline communication.

• CIM 2XX module (optional).For further information about the CIM module fitted, see the installation and operating instructions for the relevant CIM module.

If a CIM module is fitted in the CIU unit, the sensors connected to the digital input of the IO module can be remotely monitored from a centrally located SCADA system.

Grundfos GO remote control

The Grundfos GO remote control is designed for wireless IR communication with Grundfos products.The GO can communicate with the SEG AUTOADAPT pumps via a CIU unit.

The GO is to be regarded as an ordinary service and measuring tool and is therefore designed to withstand wear and stress from everyday use.
