Structural features

The pump is a single-stage, double-suction, double-vortex-chamber centrifugal pump.

The entire rotor is supported by radial bearings at both ends; the impeller is designed for anti-cavitation performance, and the constant axial force generated by the impeller, start/stop, and instantaneous axial force generated by load changes are borne by double-sided Mitchell thrust bearings.

The pump is resistant to thermal shock (38 ℃ to 186 ℃).

The pump set is equipped with a container-type mechanical seal to effectively prevent medium leakage, and the flushing scheme PLAN23.

In order to facilitate rapid maintenance, the internal components of the pump are designed as an integral core package structure, and can realize the interchangeability of all parts in the same type of pump core package.

The coupling adopts a diaphragm coupling with an intermediate section to ensure that the mechanical seal is replaced without disassembling the motor.

The pump set has the advantages of simple structure, quick disassembly and assembly, convenient maintenance, and the design life is more than 60 years.
