Description:

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.

Features:
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 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.
Parts of bearing: they consist of shaft box, bearing and bearing cover. Except 85-67,155-67,600-80,800-80 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.

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.
DM type pump apply to drainage works in steel  works  and  mine,  it  is  intended  to deliver mine  drainage  and  other  sewage whose solid content is not exceed 2% and particle is not exceed 0.5 mm.
DF pump,can transport any medium which is do not contains solids and corrosive liquid,can also used for bolier feed water pump;
DY pump,can transport any medium do not contains solids ,viscosity less than 120cp oil-like or petrol liquid.

Characteristics
 

Description
 
MD type wearable centrifugal mine water pump is used to transport the clear water and the neutral liquid of pit water with solid grain ≤1.5%. Granularity < 0.5mm. The temperature of the liquid is not over 80ºC. The pumps are suitable for water supply and drainage in mines, factories and cities. Note: When the situation is in the coal mine, explosion proof type motor shall be used.
