GeneralType D pump is single-suction, multi-stage, segmental centrifugal pump. It is widely used for water supply & drainage in fields of factory, mining and city. It is provided for delivering clear water without solid particles or other liquid which is physically and chemically similar to clear water. The temperature of the liquid is 0C~ 80C. Permissible maximum inlet pressure is 0.6Mpa.
GENERALTYPE D(D. DG. DY. DM. DF) pump belongs to single-suction, multi-stage segmental centrifugal pump.
Parameter ranges:
Capacity Q: 6~540m2/h
Head H: 33~1056m
 
the axial force gets balanced with the help of balance disc, Concerning lubrication system diluted oil is used for sliding bearing kind of TYPE 85-67\155-67\45-80\85-80\150-100 and grease for rolling bearing kind of all other pumps.
the pump rotates clockwise viewed from original drive and.
Pump is supplied together with motor and base of common or its own.
Type D serial pump can be divided to:
D: Used to deliver clear water without solid particles used to miner with the temperature range from 0C~80CThe inlet is horizontal direction.
DM: Used to deliver liquid with less solid particles or miner with the temperature range from 0C~+80C. the inlet is horizontal direction.
DG: Used to deliver clear water without solid particles or liquid similar to clear water physically and chemically with the temperature range form -20C~+150C. the inlet is perpendicularly direction.
DY: Used to deliver oil products without solid or liquid similar to water with the temperature range from-20C~+400C. the inlet is horizontal direction.
DF: Used to deliver corrosive liquid without solid with the temperature range from -20C~+150C. the inlet is horizontal direction.
the shaft of all kind type pump can be with soft packing or mechanical seal. the material through which liquid passes is made from cast iron or bronze or stainless steel and duplex stainless steel (316L)
