Multi-Stage Hot Water Centrifugal Pump

. General
This serial pump is multi-stage sectional centrifugal pump; The hydraulic models are excellent, high efficiency, saving energy, wide performance range, operating safely and steadily, low noise and long period of operation etc; It's very convenient for installing and repairing. It can pump hot water, oil and corrosive medium and other medium containing solids etc, by changing material, seal type and adding cooling system.
1. Application
Type SKD pump can deliver clear water without solids or other liquids that their physical and chemical properties are similar to clear water. It is used for supplying and draining water in mine and city projects etc.
Type SKDG pump can deliver clear water without solids or other liquid that their physical and chemical properties are similar to clear water. It is used for supplying water for boiler, delivering hot water or medium similar to hot water.
Type SKMD pump can deliver neutral water that containing solids don't exceed 1.5% (particle-size is less than 0.5mm) or other sewage. It is used for draining water (sewage) in steel company and main etc.
Type SKDF pump can deliver corrosive liquids without solids.

. Design Feature
Type SKD, SKDG, SKMD, SKDF pump consists of stator, rotor, bearing and shaft seal.
Stator: Main parts are suction casing, stage casing, discharge casing and diffuser; They are screwed by poles to form a working house. The inlet of type SKD pump is horizontal, the outlet is upward; The inlet and outlet of type SKDG pump are upward; The outlet of SKMD, SKDF pump are upward, the inlet is horizontal normally, it can be upward according to user's requirement.
Rotor: It consists of shaft, impeller, balance disk and shaft sleeve etc. The shaft delivers the power to the impeller and makes it rotate; The axial force is balanced by balance disk; The shaft sleeve is mounted on shaft to protect shaft.
Bearing: It contains bearing body, bearing and bearing cover etc. The bearing type of 85-67, 155-67, 600-60 pump is sliding bearing, and lubricated by diluents oil; Type 85-67, 155-67 also can adopt roll bearing. The other pump bearing is roll bearing, and lubricated by grease.
Shaft seal: Normally, it adopts soft packing seal, consists of sealing casing, packing and water-blocking ring etc. There are some pressure water in the sealing chamber to seal, cool and lubricate pump. The sealing water for type SKD, SKDF pump is from pump (high pressure water), for type SKDG, SKMD pump is from exterior. Usually, the seal for type SKDG, SKMD, SKDF pump is mechanical seal.
Driving: The pump is driven directly by motor through flexible coupling. The rotating direction of pump is clockwise viewed from motor.
