The SERH-50Z is a compact, engine-driven high-pressure water pump built for demanding irrigation, sprinkler, firefighting and industrial water transfer applications. Designed around a 2" (50 mm) suction/discharge configuration, this self-priming centrifugal pump delivers exceptional head and sustained flow for moving water long distances and to greater heights.

Key Features

• High total head up to 90 m (≈295 ft) and flow up to ~480–500 L/min (≈132 GPM) for heavy-duty performance.
• Durable cast iron impeller and volute with die-cast aluminum pump housing for longevity and reduced weight.
• Engine options vary by region — commonly fitted with Honda GX200 or GX220 Hi‑Revolution series engines for reliable gasoline power and easy recoil start. (Regional specs may differ.)
• Self-priming capability (max suction lift ≈8 m / 26 ft) and three-way discharge flange for flexible hose/nozzle setups.
• Portable tubular frame, low noise operation, mechanical seal options for extended duty.
