Nuton horizontal multistage centrifugal pumps are engineered to perfection with utmost care and stringent quality control at all stages to ensure

a trouble free service.

DESCRIPTION

Nuton horizontal multistage centrifugal pumps are axial suction and vertical radial delivery with threaded ports. The impellers, diffusers and

shaft of these pumps are made of stainless steel and designed to deliver the best possible hydraulic efficiency. This pump is a non-self priming

horizontal centrifugal pump with mechanical shaft seal and sealing is by means of a bellows mechanical seal.

These pumps are powered by at any enclosed fan cooled A.C. induction motor, suitable for continuous duty. Motor stator is made of low watt

loss steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration free and noise

free operations. Shaft is made of quality stainless steel. All single-phase pumps are incorporated with thermal over load protector. These

pumps require an adequate starter/motor protector control panel.

Applications

Industrial and domestic water pressure boosting and distribution

Small farms

Pumping of clean liquids in industry

Car washing

Hotels & Multistory Buildings

Salient Features

Fitted with motor protector

SS304 Impellers and stage casings

Designed for wide voltage fluctuations

Aluminum body for better the heat dissipation

Higher working pressure

Sturdy and compact

Pumped Liquids

Thin, clean, non-aggressive and non-explosive liquids without solid particles or fibers

IMPORTANT NOTES

Pump should not be operated dry. Install dry run prevent to protect the pumpset from dry running. Use appropriated size, good quality cable

and starter / protection devices. Use low fiction good quality pipes. The pipe diameters must never be smaller than the pump connections.

Install pump according to our recommended Head range. Reduce number of ends, elbows, T-bends as much as possible in the pipe line. Pump

should be run for few minutes at least once in 2 days to prevent from seizing. Use frictionless quality foot valve for Horizontal Multistage

Centrifugal Pumps. Avoid fatal electrical shock injury by disconnection power before working on or around the pumping system. Only

technically qualified personnel must perform the works complying with local electricity rules and regulations. To reduce the risk of electrical

shock operation, an appropriate earthing is mandatory. The performance data and curves are at rated voltage and only indicative. Pipe sizes

mentioned in inches are nominal pipe sizes and are nearest conversion of mm. All pumps are only suitable for pumping clear, cold, fresh, non-

aggressive, non-explosive water without abrasives, solid particles or fibers.

The conditions below apply to the curves shown on the following pages.

Ÿ Curve tolerance are according to ISO 9906, Annex-A.

Ÿ The performance are taken at rated voltage & rated frequency.

Ÿ Actual discharge depends on availability of water in Well / Tank, height of water column form the suction pipe end.

Ÿ The measurements were made with airless water at 20°C. When pumping liquids with a higher density than of

water, motor with correspondingly higher outputs must be used.

Ÿ Pipe fiction losses have not been included in the performance curves & performance tables.

Ÿ The pipe connection threads are given as per BSP standard.

Ÿ The given performance are for specific materials of constructions.

3Ÿ The main scales of the Performance curves are meter and m /h which have been given for head and flow

respectively.
