The Tsurumi BZ-series pumps are heavy-duty, submersible sewage and wastewater pumps that are designed with a shrouded single / two-channel impeller and wide passages of over 3 inches (76.2 mm) in diameter to minimize trouble due to clogged solids. In addition, as mid to large sized pumps with 22 – 75 kW of drive power, they raise the already high pump efficiency standard of predecessor sewage and wastewater pumps of the Tsurumi brand with even better energy efficiency.

The BZ-series offers a wide lineup of discharge bores ranging from 80 – 350 mm and motor outputs of 1.5 – 75 kW. Moreover, the pumps can be used with Tsurumi’s guide rail fitting device that facilitates installation and maintenance.
The BZ-series pumps come packed with a number of original technologies developed and honed over years of service including an anti-wicking cable, motor protector, dual inside mechanical seals with silicon carbide faces and Oil Lifter.

Highly reliable and durable, Tsurumi BZ-series pumps are designed and built for sound quality and continuous duty that can help you keep your systems — whether for wastewater drainage, pumping or flood control — running stably and greatly reduce your maintenance costs. As an option, the pumps can be adapted for seawater, high temperature liquids or other special application, paving the way for their use at shipyards and power plants for
