Back Pull Out End Suction by Precision Engineering Works

Being a pioneer in the use of Submersible Borewell Pumps for Firefighting, "PEW" now offers Centrifugal Back pull-out Endsuction pumps for use in places where Submersible pumps are not permitted / connot be used. These pumps are non-selfpriming with axial suction port, radial discharge port and horizontal shaft. The back pull-out design enables removal of the motor, coupling, bearing bracket and impellar without disturbing the pump housing or pipework.

• Self vented, foot mounted, center 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 L 3/D 4 ratio ensures less than 0.05 mm 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 heavy-duty requirements, if any
• Excellent parts interchangeability reduces inventory levels for spare parts to a minimum
• Special design for high temperature thermal fluids available on request
• Motor or engine driven sets
• Special mono block versions available on request

• For pumping clear/turbid water / chemicals & volatile liquids
• Air conditioning plants, power station, mine drainage, sprinkler systems for fire fighting, and booster service Can be used for oils, brine, etc

• Delivery sizes up to 250 mm
• Capacity up to 990 m3/hr
• Head up to 120 m meters
• RPM 500 to 3600
• Temperature up to 90ºC
