IN seriesCentrifugal pumps standardized to DIN-24255

2

The new standardized IN series are single-stage horizon-tal centrifugal pumps, with axial suction and radial dis-charge, buit to Standard DIN-24255, and evolved as a resultof the latest hydraulic and technological innovations applied tothe design and manufacture of the well-proven and well-known “Norma” Series of ITUR Pumps. Evolved in order tocover a wide variety of pumping requirements, they offer solu-tions and improvements with:

- High efficiency,- Sturdy design- Variety of materials, according to the liquid being pumped.- Sealed by mecanical seal or packing.- Amply-dimensioned bearings.- Standardized parts with high degree of intechangeability- Minimal and rapid maintenance.

Although these pumps are normally driven by an electricmotor, other power-drive sources may be used (diesel motor,steam turbine, hydraulic motor, ...).

The IN-Series of ITUR Pumps has been specially conceivedfor the pumping of liquids, generally clean or lightly contami-nated. The field of application of the series extends to all thepumping needs for the requirements of medium-duty services:

O Municipal or industrial water supplyO Water and oil channelling systemsO Supply of hot water to large buildingsO Climatization installationsO Constant-pressure water equipmentO Fire-protection equipmentO Irrigation

The IN-Series, standardized to DIN-24 255 comprises a totalof 47 different models, based on 34 pump sizes, where eachsize allows for one or two types of impeller (A or B).

Note.- With consultation, some of the standard construction limits laid down canbe exceeded. There are 13 larger models for flows of up to 1600 m3/h.(See catalogue for IN Series - complementary sizes).

The standard version of the electro-pump unit embodies thenormal semi-flexible coupling. Upon request, this coupling canbe supplied with a spacer. The use of the semi-flexible cou-pling with a spacer allows easy access to the pump interiorwithout the need to remove the pipes or the motor.

After removing the spacer, the assembly made up of the sup-port, cover and impeller is removed, the pump casing and themotor always remaining attached to the bed-plate. The suctionand discharges pipes remain connected.

In this way the maintenance tasks are made easier, especial-ly when dealing with a fixed installation with several pumps.

Pump Casing

With volute casing and support feet, it embodies the flangesfor the suction (axial) and discharge (radial upwards), andincorporates a wear ring. The casing-to-cover sealing iseffected by means of an embedded gasket.

Suction and discharge flanges

Integrally cast with the casing constructed to DIN-2501 crack-le-finished “RF” to DIN-2526 form C. Valid for connecting tocommercial flanges DIN PN10.

CONSTRUCTION

Auxiliary connections

The standard version comes with two connections: one forvent/primming or pressure gauge and other for drain purposes, bothdrilled and closed off with the corresponding covers.

Pump cover

Cast in one piece, of integral design, with the seal or the packing. Itincorporates the rear wear ring. It allows for connections for the sealcirculation by the liquid being pumped: plans API-01 (internal).

Wear rings

All models incorporate a forward wear ring in the casing and a rearwear ring in the cover, in order to avoid expensive repairs and toreduce their costs, through the natural loss of adjustment producedthrough time with the impeller.

Impeller

High efficiency closed impeller, cast in one piece, hydraulically anddynamically balanced. Hydraulically relieved by means of the axialthrust compensation drill holes, it is keyed to the shaft andlocked by means of two nuts.

Pump shaft

Well-dimensioned, the shaft is especially resistant to bending. It isprovided with a replaceable sleeve, sealed with the shaft itself bymeans of a O ring. Thus, changing the shaft can be avoided, in thecase of wear or abrasion in the sealing or packing area, in this wayachieving quick and cheap maintenance.

Bearing support

Of modern design, it incorporates two ball bearings, situated atboth ends of the support. Some pump sizes carry a double raw ballbearing on the pump side. It has a protective deflector against theingress of liquid.

The bearings have been calculated to give a minimum lifespan of12.000 hours, although most model exceed 18.000 hours. They aregrease-lubricated, the support incorporating greasers in its upperpart.

Standard sealing systems

By means of mechanical seal or packing. The standard versionembodies the API-01 plan of internal circulation.

• Simple mechanical DIN sealStandardized to DIN-24960. The material used in the contactingfaces and in the joints depends upon the liquid to be pumped.

PackingAsbestos-free, provided with the corresponding lantern.

The IN Series of ITUR Pumps has been studied in 6 differentversions of the highest quality Standardized Materials.

The aim of standardizing the materials is to seek Standardizedsolutions for the entire range of pumps in medium-duty ser-vice, in order to provide a fast, flexible Service for the normaldemand for this type of pumps.

Nevertheless, if the type of service for which the pumps aredestined requires it, upon request they can be manufactured inother classes of materials.

In such a case, consult the ITUR Pumps EngineeringDepartment, who will study and offer the most favourable solu-tion in each particular case.

STANDARDIZED MATERIALS

The Table below shows the seal diameters, and the size andnumber of packing rings corresponding to the IN Series ofpumps, in the sizes standardized to DIN-24255. The data iscross-referenced to the interchangeability Table on the follow-ing page, for pumps constructed of standardized materials andstandard parts.

Example: Pump IN-65/125B has a seal diameter (Group B onthe Interchangeability Table) of 28 mm, or in thecase of packing (Group A on the InterchangeabilityTable) incorporates 4 packing rings with eachsquare-sectioned of 8 mm.

The following Table shows the maximum rotational speed foreach size pump. These values have been calculated for nor-mal, continuous, pump operation, pumping clean water at20∫C, with a specific weight of 1 Kg/dm3.

For special cases, such as emergency pumps or others, withconsultation these limits can be exceeded.

The standardization of parts and materials of the IN-Series makespossible a high number of common and interchangeable partsbetween the different pump models.

This standardization infers an operational saving in costs, since itminimises the stock of parts required to guarantee the efficient main-tenance of many different models of pumps.

The components listed in the upper part of the table are standard andinterchangeable between the different types of pumps, provided thatthe same letter and colour are shown in the cross-reference box.

EXAMPLE

The pump shaft of model IN-32/125A is identical and inter-changeable, at the same material, with that of models:

» IN-32/125B» IN-40/125B» IN-32/160A» IN-32/160B

Since in the column “pump shaft” the letter A appears in all of them.

These diagrams make possible a rapid selection of the most suitable type of pump. These are occasions in which, once apump has been selected, it will also be possible to find another which may satisfy the task conditions with greater efficiencyor less NPSH required. In such cases, the final selection will be made, based on the particular curves for each pump.
