RK1828HNV | Heat-Safe Triplex Pump, 4.75 GPM 4000 PSI, Viton Seals

RK1828HNV | Heat-Safe Triplex Pump, 4.75 GPM 4000 PSI, Viton Seals

The RK1828HNV Pressure Washer Pump is an industrial-grade triplex plunger pump engineered for facilities and contractors who need reliable high pressure with excellent chemical and heat resistance. Delivering 4.75 GPM at 4,000 PSI at a smooth 1,450 RPM, it provides strong cleaning performance while reducing heat, vibration, and wear. A 24mm solid keyed shaft ensures easy integration with belt-drive or direct-drive systems, and the wet end features ceramic plungers, stainless steel valves, and a forged brass manifold for long-term durability.

The Viton (VX) seal pack sets this pump apart, offering superior elasticity and chemical resistance for hot water and detergent-heavy wash systems. With pre-filled oil, sight glass, and a vented dipstick, the RK1828HNV is designed for simple installation and predictable maintenance.

How the Pump Works

The RK1828HNV uses a triplex plunger system that delivers steady, high-pressure flow with minimal pulsation. Ceramic plungers reduce friction and wear, while Viton seals preserve packing integrity under heat and chemical load. Stainless steel inlet and discharge valves maintain flow stability, and the forged brass manifold ensures structural reliability during continuous duty. Its 1,450 RPM low-speed operation lowers heat and mechanical stress, extending the service life of bearings, packings, and oil.
