Non-self-priming, single-stage volute casing pump in a vertical close-coupled design. The back-pressure design allows for easy replacement of the drive unit without disassembling the piping. The low speed ensures quiet operation and low wear. The pump is equipped with replaceable, corrosion-resistant wear rings. The closed, balanced impeller can be individually adapted to the specific operating conditions. Balancing is carried out to grade class 6.3 according to DIN ISO 1940. This ensures optimal smooth operation and a long service life of the entire pump.
