Hermetic-Pumpen

German company Hermetic-Pumpen is a leader in developing and producing secure hermetic centrifugal pumps for refrigerating, chemical, petroleum, nuclear , pharmaceutical and food industries.

HERMETIC refrigeration pump  also guarantee exceptional qualities such as long endurance, low operation costs, reduced spare parts usage and maintenance.

Hermetic product line is presented by pumps of CNF types(single stage pumps) and CAM (multistage pumps).

Pumps CNF type are partically well suited to applications where low delievery pressures up to 60 m3/h and higher fluid flow rates are required. This range of pumps has 1 rotor that has a diameter with a pitch of 1 mm.

Pumps CAM(R) type are partically well suited to applications where high delivery pressure up to 140 m3/h and lower fluid flow rates are required. This range of pumps has from 2 to 6 rotors, suction pipe performance can be axial or radial for compatibility with WITT pumps.

Cooltech is the only official distributor of pumping equipment for refrigerating industry in Russia. We organize drop shipments of Hermetic production to any place in the world and exclusively in Russia and CIS countries.

Operating range:
Capacity Q: max. 50 m3/h
Head Н: max. 57 m.c.l.

Application sector:
Liquid gases as e.g. R 717 (NH3), R 22 (Frigen), CO2, R 134a, R 404a, R11, R12, 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.
 
Temperature:
Application conditions -50 to +30 оC

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

Constant flow regulators are intended to be installed at the outlet of refrigerant liquid pumps. These regulators accurately control the flow rate and enable pumps to safely function in a range not normally available to pumps using discharge orifices.

Orifice Plates. It is possible to protect a HERMETIC-pump from extreme flow conditions by installing 2 orifice plates.

Constant flow regulators are intended to be installed at the outlet of refrigerant liquid pumps. These regulators accurately control the flow rate and enable pumps to safely function in a range not normally available to pumps using discharge orifices.
There is no need for regular maintenance of the constant flow regulator and no readjustment is required.
