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.

General
HERMETIC pumps are completely self-contained centrifugal pumps without any shaft sealing, driven electro-magnetically by the canned motor. The CNF model has been specially developed for pumping liquefied petroleum gas. This single-stage pump design now allows for the pumping of liquefied petroleum gases with an extremely steep vapour pressure diagram. There is no need for external re-circulation of the partial flow into the suction vessel and the separator.

Design
The pumps use a single-stage impeller mounted directly on an integral induction motor. The pump volute casings and impellers are derived from the standard chemical pumps as defined
by EN 22858; ISO 2858.

Operating range

• Capacity Q: max. 50 m3/h
• Head H: max. 57 m.c.l.
