Petrochemical Pumps

ZA, ZE petrochemical process pump

ZA, ZE petrochemical pumps are single-stage, horizontal, volute casing pumps. The pump body is supported by feet and has a single-suction impeller. Axial suction and radial discharge; front and rear sealing rings and balance holes are used for hydraulic balance according to the conditions of use; the stuffing box has cooling or heating pipe joints. The shaft seal adopts packing seal, and can also adopt single-end or double-end mechanical seal. Equipped with cooling, flushing or sealing fluid systems.Consult now

ZA, ZE petrochemical pump overview:

ZA, ZE petrochemical pumps are single-stage single-suction cantilever centrifugal pumps, which are mainly used in petroleum, chemical, synthetic fiber, fertilizer, power station, metallurgy, food and medicine and other industrial sectors to transport clean or particle-containing liquid, low temperature or high temperature liquid

For neutral or corrosive liquids, the temperature of the conveying medium is generally -45 ℃ -180 ℃.

ZA, ZE petrochemical process pumps are designed according to API160 and VDMA24297 (light/medium) specifications.

ZA, ZE petrochemical pump product features:
