• High-grade seals and valves for leak-free operation under high pressure.
• Maintenance-ready layout with accessible components for servicing.
• Factory-tested performance to ensure quality and reliability right out of the box.

How the Pump Works

• Belt-drive triplex plunger system transfers power efficiently from the engine or motor while reducing strain on internal components.
• Operating at 1,750 RPM, the pump runs cooler and with less vibration than many direct-drive models.
• Precision plungers pressurize water through stainless steel valves to produce a steady 4.0 GPM at 4,000 PSI.
• Balanced flow and pressure make the pump well-suited for heavy-duty cleaning tasks and frequent use.
• Belt-drive configuration reduces wear on both the pump and the power source, helping extend overall system life.
