General Information
D type pumps are single suction multistage segmental centrifugal pumps which adopt energy efficient hydraulic model,with wide performance range,high efficiency,reasonable structure,safe and steady operation,low noise,long life performance and easy installation and maintenance.
Application
D type pump apply to mining,factory and city water supply and drain,and are used for transporting clear water without solid particles, abrader and suspended substance or other liquids that their physical and chemical properties are similar to clear water

Structural 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
Pump body:suction casing,stage casing,discharge casing and diffuser are linked 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
Parts of bearing:they consist of shaft box,bearing and bearing cover.except 600-80,800-80 type pump adopt sliding bearing and oil lubrication,other pumps adopt rolling bearing and grease lubrication
Sealing parts usually adopt packing seal,mechanical seal as well
Drive: pump is driven directly by motor through flexible coupling,viewed from the motor end, the rotating direction of pump is clockwise.
Ordering Instructions
The necessary parameters: Pump type or capacity, head at required operating point,suction pressure,density,temperature,viscosity and causticity of pumped medium etc,type of shaft sealing,motor power,voltage,insulation class,level of protection,cooling system.
