Multistage canned motor pump CAMR 2 3(HERMETIC-Pumpen GmbH)

General
The CAM and CAMR range of HERMETIC pumps are completely closed. They operate using the canned motor principle which removes the need for any shaft seal. The CAM and CAMR ranges have been developed especially for the refrigeration applications, their features include:

Low NPSH values
Pump built in two to five stages to suit the application
Able to pump 14 m3/h with a suction head of only 1,0 m
Suitable for pumping ammonia, freons and other refrigerants
The machines were examined by several classification companies and also have approval for use on ships.

The CAMR range is a special version of the CAM 2 range designed for compact plants with small collecting vessels.

The design enables:

Space saving by mounting the pump directly under the vessel
Escaping of gas through the suction port, allowing shorter re-starting times
The hydraulic data and NPSH value are identical to the CAM 2

Design
The pumps use multistage impeller mounted directly on an integral induction motor.

Operating range

Capacity Q: max. 35 m3/h
Head H: max. 130 m.c.l.

Application sector
Liquid gases as e.g. R 717 (NH3), R 22 (Frigen), CO2, R 134a, R 404a, R 11, R 12, baysilone (M3, M5), methanol, silicon oil KT3, syltherm, lithium bromide. In principle the refrigeration pumps are suitable for use with all refrigerant liquids. Please consult for any fluids not listed above.

Attitudes towards environmental awareness as well as social responsibility have steadily grown in the refrigeration industry. As an essential feature refrigeration plants must operate in a hermetically sealed way and thus, the importance of tightness has become more and more important for engineering, ecological and economical reasons. Therefore, both safety in plants as well as environmental protection play an important role in business strategy. Not only ice-cream and frozen foods need to be cooled, but almost every food. Typical application ranges include rail vehicles, toboggan-runs, bob runs, breweries, etc. in which HERMETIC pumps have been successfully used for reliable cooling of plants and production processes. HERMETIC has been dedicated to the development and production of hermetically sealed pumps for a period of 60 years. HERMETIC pumps are designed for applications in the chemical and petrochemical industry, as well as for process technologies. The refrigeration industry also benefits from this experience made in these industries. There are more than 90.000 HERMETIC pumps installed in refrigeration plants worldwide.
