Multi Stage Refrigeration Canned Motor Pump - China

The refrigeration canned motor pump is a combination unit of centrifugal pump and 3-phase AC motor, with the hydraulic section connecting directly with the motor drive shaft to constitute the rotor component jointly.

The stator can is embedded on the inner side of the stator to isolate both the rotor chamber and stator chamber, that makes the pump sealless completely.

Work Scope：

Capacity：0.5~10.5m³ /h

Head : max.

80m

Operating temp: -50~+40℃

Rated Pressure: PN25*/PN40*

Applicable Medium: Ammonia, Freon, CO2, etc.

Product Characteristics

The CLMA refrigeration pump is one with multi-stage and in a high-pressure internal circulation mode.

Part of medium is diverted from the high-pressure zone at the impeller outlet in the final stage, and capacitys through the filter net into the rotor chamber of canned motor, and returns through the shaft central hole to the hypo-high-pressure impeller zone in the next final stage.

This kind of high-pressure internal circulation mode ensures sufficiently the pressure in the rotor chamber of the canned motor to keep media from vaporizing in the pump.

That diversion also has a function of cooling the canned motor, lubricating the slide bearing.

When the pump is operating, the axial force is balanced automatically and hydraulically.

The NPSHr is very low, and when the capacity is as high as 10m3/h, it is only 0.8m for the pump.
