HORIZONTAL CENTRIFUGAL CHEMICAL PROCESS PUMP IN FRP MOULDED CONSTRUCTION

CHEMTROL FRP Pump series in India’s FIRST standard pump design non-metallic construction i.e. FRP developed to replace conventional alloy steel, lined and plastic construction pumps.

The lower RPM advantage in our anticorrosive pumps are not there since maintenance is due to corrosion and not due to normal wear and tear.  Hence the FRP pumps on 2900 RPM are most economical as compared to other on 1440 RPM.  The wetted components of these pumps viz Casing, Casin Back Cover, Impeller, Impeller nut and Gland Pusher are of solid Moulded, Joint less, Composite structures of  Fiberglass Reinforce Polyester Resin which ensure excellent resistance to corrosion and abrasion, superior impact resistance and mechanical strength.

Amongst all non-metallic MOC, if we look at physical & mechanical properties, the resistance to corrosion, abrasion, temperature, mechanical strength, the superiority of FRP is proven.  Moreover FRP components at times can be repaired unlike any other plastics.  FRP is nothing but Fibreglass Reinforced Polyester Resin.  Polyester resin being used are of Vinylester grade.  Please note that polyester resin being thermo set type of plastic, these resin set permanently.  This particular parameter facilitates strength as well as durability to FRP moulded components being incorporated in our FRP moulded pumps.  We therefore strongly feel that FRP is the best corrosion resistant / reliable material amongst all plastics.  Moreover due reinforcement of Fiberglass, the mechanical strength is better than any other non-metallic material of construction. For your perusal we are enclosing herewith “Physical & Mechanical Properties” of FRP.

VERTICAL GLANDLESS PUMP SERIES

VSP SERIES PUMPS

’Chemtrol’ VSP series pumps features a cantilevered FRP sleeved  SS316 shaft with key-way in corporate with positive locked Impeller by nut boxed with single stage volute casing.  The unique characteristic of VSP series pumps are that the casing can be roated for the choice of discharge directions,  which adds to the flexibility of installation.  Also the suction length flexibility of 300mm & 450mm are available options.

Further the impeller with positive lock nut and embedded shaft sleeve does not allow the liquid vapors penetration towards shaft since the impeller nut en capsules the impeller by a step in corporate with PTFE (Teflon) Gasket.

A support FRP moulded Adaptor with Flange and a robust mounting plate having a thickness of 25 MM as a support columm to the IP-55 Chemical duty flange mounted motor coated with flange having enough out let passages offers Non-mettalic solution contact, does not allow the liquid to be handled towards mounting plate.  Further the vapor seal in between motor and a pump protects the motor from damage due to Liquid / vapors.

The cantilevered FRP sleeved shaft and Impeller nut do not require bearing or conventional stuffing box seals.  This facilitates dry running of pump without damage.
