Immersion Multi stage Centrifugal Pump

CRK is a kind of multifunctional products. It can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure. CRK type is applicable to conveying non-corrosive liquid, While CRK is suitable for slightly corrosive liquid. 
Water supply  Water filter and transport in Waterworks, boosting of main pipeline, boosting in high-rise buildings. 
Industrial boosting: Process flow water system,cleaning system, high-pressure washing system, fire fighting system Industrial liquid conveying:Cooling and air-conditioning system, boiler water supply and condensing system, machine-associated purpose, acids and alkali 
Water treatment: Ultrafiltration system, reverse osmosis system, distillation system, swimming pool, separator Irrigation: Farmland irrigation, spray irrigation, dripping irrigation.


CRK is used for conveying cooling liquid,lubricating liquid and condensation water of machine tools,industrial cleaning equipment or other cases that application of immerged pump is suitable,and is applicable to various temperature,flow and pressure ranges.CRK is applicable to low-corrosive liquid. 
Concretely,it is applicable to electric spark.,lathe,grinding machine,processing center,cooling devices,industrial cleaning equipment,filtering system etc. 

Operation conditions 
Thin,clean non-explosive liquid without solid grains and fibers;can be used for conveying of water,cooling water solution and cutting lubricating liquid. 
Liquid temperature:Normal temperature type :-15~+70 
Warm water type +70~120 

CRK is non-self priming multi-stage centrifugal pump installed with standard motor.The motor shaft is directly connected with the pump shaft through
coupling.According to the requirement,the pump can be equipped with intelligent protector,which effectively protects pump from dry rotation,phase lack,overload etc.In order to meet the requirement of installation depth of the water tank or vessel,it is possible to install cavity body for changing length of the pump.Length for different number of stages is shown in the dimensions & weight table and the table of products supplying scope. 

The motor is fully-sealed,air cooling standard motor 2 poles 
Protection class:IP55 
Insulation class:F 
Standard voltage,50HZ:1×220230/240V
Motors for other voltages can be supplied according to the requirement.
Single phase motors with 0.37~2.2KW are available.
