The ZA series single stage end suction overhung centrifugal pump are widely used to transfer petrochemical liquid, Chemical and Oil & Gas liquid. It is designed according to API610 standards.

The pump is constructed with single impeller, horizontal installed, centre-line mounted, and its "back pull-out " design makes the pump could be easy disassembly while maintenance and replacing the rotor parts.

"Back pull-out" design meets refineries' requirements for rapid dismantling and re-assembly and is therefore often used for process pumps. The main advantage of the "back pull-out" design is that the rotating parts including the bearings and shaft seals could be pulled out of the pump casing without removing the driven motor and pipeline (the motor should be decoupled and the connection flange unscrewed to avoid possible damage).
