IntroductionD 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.ApplicationD 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 waterPerformance

formMachinery SealStructural characteristicsThe 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 sealPump body:suction
casing,stage casing,discharge casing and diffuser are linked by
bolts to form a working houseRotor: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 casingBalanced
construction:it consists of gimbals,balancing sleeve,balanced
pipelineParts 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
lubricationSealing parts usually adopt packing seal,mechanical seal
as wellDrive: pump is driven directly by motor through flexible
coupling,viewed from the motor end, the rotating direction of pump
is clockwise.Ordering instructionsThe 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.FAQ1. Q:Are you a
