Construction
Sewage pump with integrated turbulator (twister function), open multi-channel impeller and vertical threaded connection. Pump housing, strainer and impeller made of composite material. 1~ motor (jacket cooling) with integrated operating capacitor and self-switching thermal motor monitoring. Stainless steel motor housing. Oil-filled sealing chamber with double sealing: a rotary shaft seal is installed on the motor side, a mechanical seal on the pump side. Connection cable with float switch and fitted plug (type G, British BS 1363).
The twister function guarantees permanent turbulence within the pump’s intake area. The turbulence prevents the settling sediments from sinking and settling. This ensures a clean pump sump and reduces the build-up of odours.
