Working Condition：
Size: 25-400mm
Capacity: up to 2600m³/h
Head: up to 250m
Speed:450-2950r/min
Operating pressures:up to 2.5MPa
Working Temperature:-80℃~ +450℃
The flow parts of petrochemical process pump are made of stainless steel 304,304L, 316,316L, CD-4MCu, 904,904L, hastelloy alloy, etc.
Design features:
The SZA series petrochemical process pump is a single-stage single-suction cantilever type rear door structure, so it is not necessary to remove the suction and discharge pipeline when the pump is repaired. After the pump cover is removed, the suspension can be pulled out together with the rotor components from the pump body, so it’s very convenient to check and repair. The rear cover plate of the impeller has a sealing ring, which can basically balance the axial force, and the residual unbalance force is borne by the thrust bearing. When the working temperature is below 250 °c, the suspension does not need to be cooled. When the working temperature is above 250 °C ~ 450 °C, the suspension is air-cooled or water-cooled. According to different conditions, part of the pump is double volute structure, the rest is single volute. Shaft seal can use packing seal, can also use single-sided or double-sided mechanical seal, and equipped with cooling, flushing or sealing fluid system. It is driven directly by electric motor and connected with electric motor by coupling.
