IN series. Centrifugal pumps standardized to DIN-24255

IN series Centrifugal pumps standardized to DIN-24255

DESCRIPTION The new standardized IN series are single-stage horizontal centrifugal pumps, with axial suction and radial discharge, buit to Standard DIN-24255, and evolved as a result of the latest hydraulic and technological innovations applied to the design and manufacture of the well-proven and wellknown Norma Series of ITUR Pumps. Evolved in order to cover a wide variety of pumping requirements, they offer solutions 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. EASE OF MAINTENANCE The standard version of the electro-pump unit embodies the normal semi-flexible coupling. Upon request, this coupling can be supplied with a spacer. The use of the semi-flexible coupling with a spacer allows easy access to the pump interior without the need to remove the pipes or the motor. After removing the spacer, the assembly made up of the support, cover and impeller is removed, the pump casing and the motor always remaining attached to the bed-plate. The suction and discharges pipes remain connected. In this way the maintenance tasks are made easier, especially when dealing with a fixed installation with several pumps. Although these pumps are normally driven by an electric motor, other power-drive sources may be used (diesel motor, steam turbine, hydraulic motor,...). APPLICATIONS The IN-Series of ITUR Pumps has been specially conceived for the pumping of liquids, generally clean or lightly contaminated. The field of application of the series extends to all the pumping needs for the requirements of medium-duty services: O Municipal or industrial water supply O Water and oil channelling systems O Supply of hot water to large buildings O Climatization installations O Constant-pressure water equipment O Fire-protection equipment O Irrigation PUMP DENOMINATION IN Series DN of discharge outlet, in mm Nominal diameter of impeller, in mm Impeller type IN-100/250 B RANGE OF THE SERIES The IN-Series, standardized to DIN-24 255 comprises a total of 47 different models, based on 34 pump sizes, where each size allows for one or two types of impeller (A or B). Service limits - Maximum flow:.....................600 m3/h - Maximum height differential...........105 m.c.a. - Maximum casing pressure (at 20 C).....10 kg/cm2. - Maximum suction pressure............5 Kg/ cm2. - Maximum speed....................3.600 rpm - Maximum temperature...............140 C - Maximum viscosity..................20 cst (2,9 E) Note.- With consultation, some of the standard construction limits laid down can be exceeded. There are 13 larger models for flows of up to 1600 m3/h. (See catalogue for IN Series - complementary sizes). CONSTRUCTION Pump Casing With volute casing and support feet, it embodies the flanges for the suction (axial) and discharge (radial upwards), and incorporates a wear ring. The casing-to-cover sealing is effected by means of an embedded gasket. Suction and discharge flanges Integrally cast with the casing constructed to DIN-2501 crackle-finished RF to DIN-2526 form C. Valid for connecting to commercial flanges DIN PN10. 2

Auxiliary connections The standard version comes with two connections: one for vent/primming or pressure gauge and other for drain purposes, both drilled and closed off with the corresponding covers. Pump cover Cast in one piece, of integral design, with the seal or the packing. It incorporates the rear wear ring. It allows for connections for the seal circulation by the liquid being pumped: plans API-01 (internal). Standard sealing systems By means of mechanical seal or packing. The standard version embodies the API-01 plan of internal circulation. Simple mechanical DIN seal Standardized to DIN-24960. The material used in the contacting faces and in the joints depends upon the liquid to be pumped. Wear rings All models incorporate a forward wear ring in the casing and a rear wear ring in the cover, in order to avoid expensive repairs and to reduce their costs, through the natural loss of adjustment produced through time with the impeller. Impeller High efficiency closed impeller, cast in one piece, hydraulically and dynamically balanced. Hydraulically relieved by means of the axial thrust compensation drill holes, it is keyed to the shaft and locked by means of two nuts. Pump shaft Well-dimensioned, the shaft is especially resistant to bending. It is provided with a replaceable sleeve, sealed with the shaft itself by means of a O ring. Thus, changing the shaft can be avoided, in the case of wear or abrasion in the sealing or packing area, in this way achieving quick and cheap maintenance. Detail of the mechanical seal with plan API-01 (internal) Packing Asbestos-free, provided with the corresponding lantern. Bearing support Of modern design, it incorporates two ball bearings, situated at both ends of the support. Some pump sizes carry a double raw ball bearing on the pump side. It has a protective deflector against the ingress of liquid. The bearings have been calculated to give a minimum lifespan of 12.000 hours, although most model exceed 18.000 hours. They are grease-lubricated, the support incorporating greasers in its upper part. Packing detail with plan API-01 (internal). 3

STANDARDIZED MATERIALS The IN Series of ITUR Pumps has been studied in 6 different versions of the highest quality Standardized Materials. The aim of standardizing the materials is to seek Standardized solutions for the entire range of pumps in medium-duty service, in order to provide a fast, flexible Service for the normal demand for this type of pumps. Nevertheless, if the type of service for which the pumps are destined requires it, upon request they can be manufactured in other classes of materials. In such a case, consult the ITUR Pumps Engineering Department, who will study and offer the most favourable solution in each particular case.

PARTS INTERCHANGEABILITY The standardization of parts and materials of the IN-Series makes possible a high number of common and interchangeable parts between the different pump models. This standardization infers an operational saving in costs, since it minimises the stock of parts required to guarantee the efficient maintenance of many different models of pumps. The components listed in the upper part of the table are standard and interchangeable between the different types of pumps, provided that the same letter and colour are shown in the cross-reference box. EXAMPLE The pump shaft of model IN-32/125A is identical and interchangeable, 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 are occasions in which, once a pump has been selected, it will also be possible to find another which may satisfy the task conditions with greater efficiency or less NPSH required. In such cases, the final selection will be made, based on the particular curves for each pump. Range coverage Complementary sizes 6
