Water pump 2.4.2

with electric motorself-primingcentrifugal

This pump is a centrifugal pump with single-stage, double-suction and double volute. The entire rotor is supported by transverse bearings at two ends; the impeller is designed with anti-cavitation performance with the constant axial force, start/stop as well as transient axial force generated with the change of load sustained by a double-faced Michell thrust bearing. The pump is designed with heat shock resistance (38°C-186°C). The pump set is equipped with a cartridge mechanical seal to effectively prevent medium leakage with the flushing plan of PLAN23. For facilitating rapid overhaul, the internal components of the pump are designed as an integral cartridge structure and can realize interchangeability of all components inside the pump set cartridge of the same model. Diaphragm coupling is adopted as the coupling with a middle section which can ensure replacement of mechanical seal without detaching the motor. With simple structure, quick disassembly and assembly, convenient maintenance ,this pump set* s design life is more than 60 years.
