TSURUMI Submersible pump BZ sewage
The BZ sewage pumps are of cast iron construction and are fitted with shrouded single-channel impellers. This design provides substantial flows and enables the pump to pass 80mm solid particles without clogging, and provides reliable operation in pumping stations, sewage works and effluent processing. Pumping capacity exceeds many other pump brands of a similar design. These pumps have 4 pole motors to give improved longevity and wear resistance.
The 11kW versions feature star-delta starting. Available in three-phase only. The 403 (<3.7kW)/ 420 (>5.5kW) stainless steel shaft is fitted with an ultra hardwearing double mechanical seal (inboard: silicon carbide-silicon carbide), in an oil chamber. They are available free- standing or for fixed installations, when supplied with the guide rail
(auto-coupling) kit. The latter includes a pedestal, guide hook, top bracket and lifting chain, but not rails. Supplied with 10 metres of heavy duty rubber power cable.
