PSFW Series - Submersible Wastewater Pumps

The Tsurumi PSFW Series is the auto-alternation variant of the PSF resin-made high-head wastewater pump. Designed for paired operation with a PSFA automatic pump, the system alternates pump operation according to changing water levels without requiring a separate control panel.

The PSFW incorporates three float switches for automatic level control, enabling the paired pumps to share operating duty while providing automatic wastewater pumping. The two published PSFW models span 2.2–3.7 kW, providing a compact solution for higher-head wastewater applications requiring automatic alternating operation.
