     "PEW" End Suction Pumps are non- self-priming single-stage, centrifugal volute pumps with axial suction port, centrally placed radial discharge port and horizontal shaft. Volute chamber and impellers are designed to give the best possible hydraulic efficiency and good suction lift characteristics. Most modern and highly sophisticated machinery and technology are engaged in manufacturing these pumpsets, using quality raw materials, dynamically balanced impellers and rotors to ensure long life.

     These pumpsets are powered by a totally enclosed, fan cooled, AC Induction, two pole motor suitable for continuous duty with main dimensions complying with IEC standards. Motor stator is made of low watt-loss, silicon steel laminations assembled under pressure and rigidly locked in the frame. The windings are of high-grade enamelled copper wire and are varnish impregnated. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the pumps.

 

Features:

• Self vented, foot mounted, centre suction volute casing & single stage, closed / semi open dynamically balanced non-clog impeller ensure unimpeded liquid flow.
• Supporting feet are cast integral with the casing along with suction and discharge nozzles.
• Flange drilling standards as per DIN 24255 / ISO 2858 or as per customer's requirement.
• Designed for 16 bar working pressure with optional casing for a working pressure of up to 20 bar.
• A robust and solid construction that guarantees long life even under high suction pressure conditions.
• Heavy-duty, deep-grooved closed ball bearings with minimum 50,000 hours operating life under normal conditions ensure no dirt intrusions. (Grease lubricated; oil lubrication available on request).
• Heavy-duty, stiff solid shaft design with low L3/D4 ratio ensures less than 0.05mm shaft deflection at the seal face in all operating conditions which extends seal life.
• Seal housing is constructed to accommodate different seal/gland designs, so as to meet severe heavy-duty requirements, if any.
• Excellent parts interchangeability reduces inventory levels for spare parts to a minimum.
• Special design for high temperature thermic fluid available on request.
• Motor or engine driven sets.
• Special monoblock versions available on request.
