MD type wearable centrifugal mine water pump is used to transport the clean water and pit water with solids ≦1.5%. Solids diameter<0.5mm. The temperature of the liquid is not over 80℃. 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.
Performance Ranges
Capacity(Q) 25~840m³/hr
Heead(H) 60~1798m
Structure
Model MD pumps consist of four parts: stator, rotor, bearing and shaft seal:
Stator: mainly include suction casing, stage casingm discharge casing and diffuser. They are screw up by poles, to beome a working housing. The suction direction of type MD pump is horizonal and discharge direction is vertical.
Rotor: mainly include shaft, impeller, balance disc and bearing cover etc.
Bearing parts: mainly include bearing housing, bearing, and bearing cover etc. The lubrication type can be grease and oil.
Shaft seal: It is usually adopted soft packing seal, mechanical seal.
