The SUMO range of submersible multistage centrifugal pumps are designed for pumping clean, non-aggressive water in various domestic and light duty applications. They are particularly suitable for wells and boreholes, though can also be used for water transfer from tanks, irrigation and pressure boosting applications as an alternative to a conventional dry mounted pump. A particular design feature is the jacketed motor arrangement which provides excellent motor cooling and allows the pump to work semi-submerged. Another innovative feature is double mechanical seals with an intermediate oil chamber for total motor protection.
Pump construction is 'Noryl' plastic impellers and diffusers and stainless steel pump casing. 20m drop cable and a low level floatswitch are provided as standard.
Enclosed and rewindable liquid cooled, non-overloading induction motor designed for continuous operation. Single phase motors incorporate a thermal cut-out in the winding to protect against overloading and the pump can be connected directly to the mains power supply through a 1 0amp fuse or MCB.
