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.
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
Motors for other voltages can be supplied according to the requirement.
Single phase motors with 0.37~2.2KW are available.

Following conditions are suitable for the performance curves shown bellow:
1. All curves are based on the measured values of 50Hz: Constant motor speed 2900rpm or 2950rpm
2. Curve tolerance in conformity with ISO9906 Annex A.
3. Measurement is done with 20C air-free water, kinematic viscosity of 1mm ²/sec.
4. The operation of pump shall refer to the performance region indicately by the thickned curve to prevent overheating due to too small flow rate or overload of motor due to too large flow rate.
