RC

The Grundfos RC pumps are used for circulation of liquid refrigerants in refrigeration systems.

RC pumps have been designed and optimised for use with CO₂ as refrigerant but are also applicable to NH₃ (Ammonia) and selected HFCs.

The NPSH required is low and reduces the need for the traditional loss generating protective devices can help system designers in reducing the dimensions and cost of the system. The RC pumps have an innovative design in stainless steel which makes specially suited for use with high pressure refrigerants (CO₂) – the pump has only one seal between the refrigerant side and the ambient. A version with welding connections eliminates the use of counter flanges and possible leakages in flange connections.

Applications
