ZE/ZF END SUCTION PUMP RANGE

Heavy-duty end suction pumps make light work of liquids

The ZE/ZF are ideal pumps for arduous industrial applications handling clean, cold or hot liquids, including hydrocarbons and light chemicals. The ZE/ZF pumps are industrial process pumps with a modular design to provide maximum interchangeability of spares.

Main benefits

Centerline mounted to ease thermal expansion without jeopardizing the shaft alignment
Wear rings and balance holes optimized to maximize seal and bearing life
Extra heavy-duty shaft for low shaft deflection and long life of seal and bearings
Cooling chamber easy to clean
Low noise fan for high ambient or operating temperatures

Main applications

Booster pumps for medium size boiler feed water units in conventional thermal and combined cycle power stations
Hot water circulation pumps in district heating plants and boiler circulation in industrial power generation
Auxiliary pumps in conventional and renewable thermal power stations
Main and auxiliary Heat Transfer Fluid (HTF) circulation in solar power stations
Feed pumps, second pass pumps and Energy Recovery Device (ERD) circulation pumps in desalination by reverse osmosis

Main design features

Enclosed impeller provided for lower Net Positive Suction Head Required (NPSHr)
Self venting, centerline discharge
Casing feet and baseplate designed to meet API 610 nozzle loads and moments and increased thermal expansion
API 682 seal chambers
Axial thrust bearings are back-to-back angular contact or taper roller for heavy-duty applications
