Centrifugal pump system with horizontal suction and vertical pressure port, consisting of:
Self-priming, single-stage jet pump with continuous motor pump shaft and direction of bidirectional mechanical seal. Directly flanged AC or three-phase motor with built-in thermal motor protection switch and condenser for AC version.
Pump control by means of control kit with diaphragm pressure vessel, pressure switch and pressure gauge (0 – 6 bar).
The pressure tank is equipped with a robust replaceable membrane made from the high performance material EPDM.
All parts that come into contact with the fluid are corrosion-proof.
Pump system ready for connection, pre-assembled and wired with 2 m cable and mains plug. Ideally suited for use in garden and hobby areas. Connection via terminal box for three-phase version.
