Single and Multi Stage Ammonia Refrigeration Original Hermetic Pumpen Canned Motor Pump

Product Description

Product DescriptionSingle and Multi Stage Ammonia Refrigeration Original Hermetic Pumpen Canned Motor Pump
Hermetic refrigeration 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 Hermetic pumps sealless completely. When the pump is operating, the axial force is balanced automatically and hydraulically.
The stator can is imported from Germany, that is formed by rolling in a special process to have a high precision, a good quality free from wedling defects, that ensures sufficiently the canned motor pump to operate reliably and stably.
The slide bearing is in FH82A to have such advantages as high strength, good wear resistance, etc, and a service life 10 times more than resin impregnated graphite bearing.
Hermetic refrigeration pump consists of CNF series and CAM/CAM2 series, in which CNF series is in a horizontal single-stage structure and CAM1/CAM2 in a horizontal multi-stage structure, and both are in the form of axial suction, radial discharge.
Refrigeration Pump Series CAM1/CAM2
Structural characteristics:
Series CAM1/CAM2 refrigeration pump is one with multi-stage and in a high pressure intermal circultation 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. Refrigeration Pump Series CNF
Structural characteristics: Series CNF refrigeration pump is one with a single stage and in a high pressure internal circulation mode. Part of medium is diverted from the high pressure zone at the impeller outlet, and capacity through a filter net into the shaft central hole, where it is further pressurized by the auxiliary impeller before coming into the rotor chamber of the canned motor, and finally, it returns to the high-pressure zone at the impeller outlet. 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
