Product Description

Product Description

MD TYPE pump is a horizontal self-balancing centrifugal pump, divided into single suction multistage structure and double suction multistage structure according to the suction form. The typical characteristics of this type of pump in the structure of the balance disk system completely cancel the balance of axial force, using the impeller symmetrical automatic distribution balance axial force, this innovation makes the multistage pump in the allowed with high efficiency and energy saving, stable and reliable, less wear, reduce costs and other advantages.
 

It can be used to transport clean water WITHOUT solid particles (abrasives), CLEAN water without suspended matter or other liquids with physical and chemical properties similar to clean water. It is also possible to change the material of the pump (or the material of the pump flow parts), seal the form and increase the cooling system for conveying hot water, oil, corrosive and abrasive media, etc.
 

Model significance:

Such as MD450-60 x9 (P)

MD------ denotes wear-resistant horizontal multistage centrifugal pump for mining

450------- indicates that the design point flow is 450m3/h

60--------- indicates that the design point head is 60

9---------- indicates 9 pump levels

 

Scope of performance:

Pump suction and discharge caliber 40-350mm.

Flow rate Q = 3.75 ~ 1360 m3 / h.

Lift H = 92 ~ 1433 m.

Motor power N=7.5 to 4000KW.

It is used to transport neutral mine water and other similar sewage with particle size less than or equal to 105%, particle size less than or equal to 1.3mm and temperature of -20~80 degrees.
