Product Description

D,DG high pressure multistage centrifugal pump

Brief description :

D,DG high pressure multistage centrifugal pump consists of two or more impellers. They are used in pumping services of moderate-to-high TDHs (total dynamic head). Each stage is essentially a separate pump.

All the stages are within the same housing and installed on the same shaft. Eight or more stages can be installed on a single horizontal shaft. Each stage increases the head by approximately the same amount. Multistage pumps can be either single or double suction on the first impeller.

Pump Applications( Centrifugal sewage pump for wastewater ):
water supply,booster systems,irrigation,fire fighting,snow making,boiler feed,condensate,
district heating,osmosis and ultra filtration,spray water system,cleaning systems,mining.

Handled liquids( Centrifugal sewage pump for wastewater ):
Pure as well as slightly contaminated media
such as cold and hot water (temperature
up to 120 degree Celsius.) ,condensate, oil 
suspensions ,acids as well as their watery solutions
caustic solutions and brine

CONSTRUCTION :
1. Stator: The main parts are suction casing, stage casing, discharge casing and diffuser, they are screw up by poles,
to become a working house. The suction direction of type D pump is horizontal, and the discharge direction is upward.

2. Rotor: It is consist of shaft, impellers, balance disc and shaft sleeve etc. Shaft supplied power to impeller; The axial force is balanced by balance disc; The sleeve mounted on shaft to protect shaft.

3. Bearing parts: It is consist of bearing body, bearing and bearing cover etc. The bearing of type 85-67, 155-67, 600-60 pump is sliding bearing, lubricated by diluted oil, the other pump bearing is rolling bearing, lubricated by grease.

4. Shaft seal: It is usually adopted soft packing seal,consist of sealing house on suction casing,packing,blocking water ring, the sealing house have some pressure water,to cool,lubricate and seal pump.The pressure water of Type D pump comes from pump itself.

Drive: The pump is driven directly by motor through elastic coupling. The rotation of pump is clockwise looking from motor to pump.
