ZA, ZE petrochemical process pump

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:

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, radial discharge;

According to the conditions of use, the front and rear sealing rings and balance holes are used for hydraulic balance;

The stuffing box has cooling or heating pipe connections. 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.

The rated pressure rating of the suction and discharge pipe flanges is the same.

The bearings are lubricated with clean No. 22 machine oil.

Rotation direction of the pump: viewed from the prime mover side, it rotates clockwise.
