Refrigeration Pump Series CAM1/CAM2

Structural characteristics:

Series CAM1/CAM2 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 capacity 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.
