 D multistage pump overview          

D、DM type  pumps are single suction multistage segmental centrifugal pumps which adopt energy-efficient hydraulic model,they conform to GB/T5675 (Centrifugal Pump  Technical Condition III),with wide performance range,high efficiency,reasonable structure,safe and steady operation,low noise,long life performance and easy installation and maintenance.

 D multistage pump feature             

The pump series is installed horizontally, the inlet is horizontal and the outlet is upward, they can be changed as required. The pump consists of pump body, rotor, balanced construction, bearing and seal.

inked by bolts to form a working house. Rotor: it consists of shaft, impeller, 
shaft sleeve, balance disk etc. The spare parts of shaft are rolled into one by 
straight supported by bearing at both ends keys and sleeve nuts, the rotor is in  pump casing.
Balanced construction: it consists of gimbals, balancing sleeve, balanced pipeline.
