Pumpmaster SEH-50X 3.5HP HONDA GX120 Engine Driven FlowMate Transfer Pump (Max 600LPM/300kPa)

The Pumpmaster SEH-50X Engine Driven High-Flow Transfer Pump is a compact, robust petrol pump designed for applications requiring high water volume rather than high pressure. Built around the reliable Honda GX120 4-stroke petrol engine, the SEH-50X delivers strong flow performance in construction, industrial, irrigation, and general water transfer applications where mains power is unavailable.

Featuring a 2″ centrifugal pump design, the SEH-50X is capable of delivering flow rates of up to 600 litres per minute with a maximum head of approximately 30 metres (≈300kPa). This makes it ideal for rapid dewatering, tank transfer, and moving large volumes of water over short to moderate distances. 

The pump is built for durability, with cast iron impeller and volute components to ensure long service life under continuous operation. A die-cast aluminium pump casing keeps overall weight low without sacrificing strength, while the integrated steel roll cage and vibration isolators protect the pump during transport and operation. A low-oil shutdown sensor is fitted as standard to help protect the engine from damage.
