WHW3220N | 7.9 GPM 2900 PSI Hot Water Pump 1450 RPM Use Rated

WHW3220N – High-Volume Hot Water Industrial Triplex Plunger Pump

Overview

The WHW3220N is a high-capacity commercial triplex plunger pump built for hot water applications and continuous-duty industrial cleaning systems. Delivering 7.9 GPM (up to 8.5 GPM under optimal output) at 2900 PSI and running a smooth 1450 RPM, it provides the high flow, strong pressure, and long-lasting reliability required for multi-gun wash bays, trailer systems, and high-throughput cleaning operations.

With bronze connecting rods, stainless steel valves, ceramic plungers, and a precision-machined brass head, this model is engineered for durability in demanding heat and pressure environments. A 24mm solid shaft ensures compatibility with belt-drive and direct-drive systems, while an integrated sight glass, vented dipstick, and pre-filled break-in oil simplify maintenance.

How the WHW3220N Works

The WHW3220N uses a triplex plunger system with three ceramic plungers cycling in sequence to produce a smooth, pulse-free high-pressure water flow. This design reduces seal stress, improves efficiency, and delivers stable output at 1450 RPM.

• Ceramic Plungers: High resistance to heat, abrasion, and impurities.
• Bronze Connecting Rods: Heavy-duty durability for long continuous run times.
• Stainless Steel Valves: Precise sealing and long-term corrosion resistance.
• Brass Head: Precision-machined for heat and chemical resistance.
• Oil Bath Lubrication: Sight glass and dipstick simplify condition checks.
