RW21HT | 5.5 GPM 3500 PSI Pump 1450 RPM Hot Water Rated

Annovi Reverberi RW21HT Hot-Water Industrial Pump

The RW21HT is a hot-water-rated industrial pressure washer pump built for commercial systems that require both high power and high-temperature resistance. Delivering 5.5 GPM at 3,500 PSI and running at 1,450 RPM, this pump is engineered for continuous-duty cleaning in car washes, dairy farms, food service, and municipal maintenance operations.

With ceramic plungers, oversized bearings, stainless steel valves, and heat-resistant seals, the RW21HT is designed to operate with inlet water temperatures up to 185°F. Its 24mm solid keyed shaft ensures broad compatibility, while features like the sight glass and pre-filled break-in oil simplify installation and service.

How It Works

The RW21HT uses a triplex plunger system, where three ceramic plungers operate in sequence to deliver smooth, consistent water flow. Ceramic plungers resist heat and abrasion, while stainless steel valves ensure precise intake and discharge regulation under high-pressure conditions.

The pump’s hot-water design allows it to safely handle inlet temperatures up to 185°F. Its forged manifold, heat-rated seals, and oversized bearings provide reliable long-term performance even in harsh, high-temperature commercial environments.

The 24mm solid keyed shaft ensures stable torque transfer in belt-drive or direct-drive installations.
