Two stage liquid ring vacuum pumps series CDS and NP suitable for deep vacuum applications. CDS is a compact line designed to minimize the floor space requirements by offering short and integrated bearing brackets in combination with the motor supporting lantern option up to 15 kW size mainly dedicated to the OEM market. For capacity higher than 900 m3/h, the NP series is available with long bearing brackets in order to offer complete flexibility on the mechanical seal selection to meet any process requirements. On both series it is possible to axially adjust the rotor assembly from outside, thus perfectly centering it inside the pump and achieving best performance and reliability. Standard construction is cast iron with bronze or stainless steel impellers; alternatively, pumps are available completely in stainless steel execution. Special alloys are available upon request. They are widely used in the process industry and power generation for gas and vapour extraction, evaporation or impregnation. ATEX version available on request. The flexibility of the liquid ring technology opens the door to the definition of continuos new applications.
