Refrigerant Pumps |
| |
IDMC markets liquid refrigerant pumps designed and manufactured by Witt, Germany. Refrigerant pumps are required to deliver refrigerant to evaporators in industrial refrigerant plants. The heat transfer efficiency achieved with these system are exceptionally good. |
| |
GP Type Open Refrigerant Pumps
These are strong, open-type standard pumps driven by standard flanged or flame proof motor. These pumps have particularly favourable characteristics for NH3, since gas flows with the liquid, the pumps possess automatic "self-recovery" properties. A wide range of models are available with and without standard flange-mounted motor and accessories. The pumps supply evaporators with refrigerant from a central surge drum. The open type pumps are available in models GP 41,42, 51, 51A and 52. |

The easy distribution of the refrigerant to evaporators, including remote units, the simple regulation and the possibility of a convenient hot gas defrosting are compelling reasons to design a refrigeration plant as a pump circulation system.
Application on the high pressure side of the refrigeration plant serve the purpose to reduce the energy consumption of plants with expansion valves. |

HRP Type Hermetic Refrigerant Pumps
Wherever regulations require, a hermetic execution of the refrigerant system, Witt refrigerant pumps of the HRP series are the preferred choice. The pump is driven by a canned motor. The stator housing withstands the high nominal pressure of pumps giving unrivalled safety. The hermetic pumps are available in models HRP 10080, HRP 8050, HRP 5040 and HRP 3232.
The HRP 3232 is designed for all common refrigerants, CO2 refrigerant or brine. With these four sizes, a large range of application for industrial refrigeration is covered. |
