The KOSHIN SERH-50BDHR is a commercial-grade, high-pressure self-priming centrifugal pump engineered for demanding applications such as firefighting, overhead irrigation, industrial washdown and emergency water transfer. Built for durability and portability, this diesel-driven SERH model delivers exceptional head performance and reliable operation in remote or heavy‑use environments.

Key Features & Benefits

• Diesel power: compact Hatz diesel engine option (HATZ 1B20) for robust torque and extended runtime in diesel-only fleets.
• High-pressure, self-priming centrifugal design ideal for long‑range, high‑head pumping and jet-washing tasks.
• Heavy-duty construction: cast iron impeller and volute with aluminum pump housing and stainless steel shaft for corrosion resistance and long service life.
• Portable frame and moderate weight make it suitable for rapid deployment by fire services, contractors and agricultural crews.

Performance & Technical Highlights

The SERH-50BDHR offers high flow at elevated heads (examples from manufacturer tests include over 20,400 L/h at a 10 m head with progressively lower flows at increasing head), self-priming suction capability, and a compact fuel tank for extended operations. These specs make it a strong choice when high head (pressure) and reliability are required.

Who Should Choose the SERH-50BDHR

Select this Koshin pump if you need a rugged, high‑pressure diesel pump for firefighting standby, commercial irrigation, industrial cleaning or any application demanding sustained pressure, self-priming performance and corrosion‑resistant pump components.
