The ZDG series boiler feed pump is horizontal multistage section centrifugal pump, with the features of high efficiency', wide performance range, steady and safety operation, low noise and easy installation.
It can deliver the clean water, hot water, corrosive liquid, seal water and oil liquid by selecting different mater of flow passage parts. It is widely applied to industrial water supply and discharge, high building water supply, fire fighting applications, mining water discharge, long distance water transmit, and boiler water feeding, etc.
The multistage pump is consisted of stator, rotor, bearing, shaft seal.
1. Stator: consisted of suction casing, discharge casing and diffuser. The casing are held together by external tie rod.
2. Rotor: consist of shaft, impellers, balance disc and shaft sleeve etc.
3. Bearing parts: consisted of bearing housing, bearing and bearing cover. It's generally rolling bearing lubricated by grease.
4. Shaft seal: packing seal or mechanical seal.
