HERMETIC refrigeration pumps

HERMETIC canned motor pumps meet the highest requirements for quality, safety and flexibility, regardless of whether they are used in applications with NH₃, CO₂, water-glycol mixtures or synthetic oils. Safety and economy are not mutually exclusive. Our pumps have been used in various applications for decades around the world. With over 400 different pump variations, customer-specific adaptations from a quantity of 1 and our emergency pump warehouse, we are always at your side. We also support you with many different certificates such as for marine applications or the certificate C CSA US for the American and Canadian market.

CO₂ refrigeration pump PN 65

New

The new pump series for CO₂ impresses with a high pressure resistance of up to 65 bar in operation, which is tested with a pressure of 97.5 bar. The pumps are characterized by high energy efficiency, compactness and maintenance-free operation. The energy efficiency of the motor increased significantly without motor can. The compact design combined with exceptionally low NPSHR values also enable very compact designs of the refrigeration systems.
