MD(S) type pump is a kind of mineral wear-resistant multistage centrifugal pump improved and designed based on D type pump.It is characterized by its wear-resistance,long service time,and it is used to transmit mine water whose solid particle content is less than 1.5%(particle diameter smaller than 0.5mm),and other similar liquids.Transmitted medium temperature is no more than 80℃.
Application Area
Specially applied for mineral drainage.
Structural Characteristics
The series of horizontal multistage centrifugal pump is supported by two ends.The casing part is sectional.The pump is driven by means of the connection of flexible coupling and motor.The pump rotates clockwise from the direction of drive end.(D580-70(1)、MD580-70(1) The pump rotates anticlockwise from the direction of drive end).
Stator part
It is mainly connected to be a whole part by suction section,middle section,discharge section stuffing box using tension bolts and bolts,and the discharge is vertically upwards and the suction is horizontal.
Rotor part
It is mainly made up of shaft,impeller,balance plate,shaft sleeve,etc.
Seal of pump
The stationary joint face between the suction section,middle section and discharge section is sealed with gaskets.
The choke flow seal is adopted between different stages of pump.
Packing seal is used for shaft seal of two sides of the pump.
The water deflector is used for preventing water from entering the bearing.
Bearing part
The whole rotor is supported by the roller bearing at the two sides of bearing.The grease lubrication is applied for the bearing.
