HRP
Hermetic refrigerant pump
It delivers liquid refrigerant where it is needed. Safe and reliable.
The type HRP refrigerant pump is hermetically sealed thanks to its integrated canned motor, and it delivers up to 66m³/h or to 65m height. It is suitable for almost all refrigerants and it can be used for high operating pressures of up to 90 bar. This is particularly important when using CO2.
Since the HRP was introduced for the first time it is constantly improved for an optimize operation within the industrial refrigeration.
Thanks to its design, the HRP offers constant, reliable refrigerant delivery – even with varying pressures that occur when compressors are changing loads.
If the installation instructions are followed, the HRP is completely maintenance-free and long-lasting.
