The KOSHIN PGH-50DHR is a heavy-duty diesel-driven thermoplastic centrifugal pump designed for corrosive liquids, seawater and chemical transfer. Built for reliability in marine, agricultural and industrial dewatering applications, this self-priming 2" (50 mm) pump pairs Koshin corrosion-resistant PET pump end construction with a robust Hatz diesel engine for long life in harsh conditions.

• Engine: Hatz 1B20 diesel (compact, durable diesel power for continuous field use).
• Construction: PET (Polyethylene Terephthalate) thermoplastic casing, impeller and volute for chemical and saltwater resistance.
• Seals: Carbon-ceramic mechanical seal with EPDM components for chemical compatibility.
• Connections: 2" BSP female inlet and outlet (50 mm).
• Performance: flow approximately 480–500 L/min with total head up to ~25–26 m and max suction lift ≈ 8 m (model-dependent).
• Portability: rugged framed design; diesel model weight around 57 kg.

Specifications and performance may vary by configuration; diesel PGH-50 variants commonly feature electric or recoil start options and are supplied with hose nipples, strainer and fittings for fast deployment on irrigation, flood response, pool maintenance, marine bilge work, fertilizer transfer and general water/chemical pumping.

Why choose the PGH-50DHR: proven Hatz diesel reliability, PET thermoplastic wet end for chemical resistance, carbon-ceramic seal durability and 2" ports for standard hose compatibility—making it a versatile, corrosion-resistant solution for demanding transfer, dewatering and seawater applications.
