MD Multistage Pump Introduction:
Multistage Pump is single-suction,multistage,centrifugal pump,It is
widely used for water supply&drainage infields of factories
mines and cities.It is provided for delivering clear water without
solid particles or other liquid which is physically and chemically
similar to clear water. The temperature of the liquid is 0°C~80°C.
Permissible inlet pressure is 0.6MPa
MD Multistage Pump Features:
1. Stator: The main parts are suction casing, stage casing,
discharge casing and diffuser. They are screw up by poles, to
become a working house. It is horizontal, the discharge direction
is upward; The discharge and suction direction of them are both
upwards, and the suction direction is horizontal usually, also they
can be made upward according to user's requirement.
2. Rotor: It is consist of shaft, impellers, balance dic and shaft
sleeve etc. Shaft supplied power to impellers; The axial force is
balanced by balance disc; The sleeve mounted on shaft to protect
3. Bearing parts: It is consist of bearing body, bearing and
bearing cover etc. The bearing of type 85-67, 155-67, 600-60 pump
is sliding bearing, lubricated by diluted oil, the other pump
bearing is rolling bearing, lubricated by grease.
4. Shaft seal: It is usually adopted soft packing seal, consist of
sealing house on suction casing, packing, blocking water ring, the
sealing hose have some pressure water, to cool, lubricate and seal
pump. The pumps usually adopt mechanical seal.
5. Drive: The pump is driven directly by motor through elastic
coupling, the rotation of pump is clockwise looking from motor to
