WHW2115N | 5.55 GPM 2200 PSI Hot Water Pump 1450 RPM Duty Use

WHW2115N Hot Water Industrial Pressure Washer Pump – 5.55 GPM, 2200 PSI

• The AR North America WHW2115N is a high-performance hot water pressure pump engineered for
  continuous-duty cleaning where thermal stability and long service life are critical.
• Delivers 5.55 GPM at 2200 PSI while operating at 1450 RPM, providing balanced flow
  and consistent pressure for demanding commercial and industrial environments.
• Built around a triplex ceramic plunger design, forged brass manifold, and
  thermal-resistant seals to thrive in hot-water systems where standard cold-water pumps quickly wear out.
• Optimized for hot-duty applications such as fleet maintenance, food and beverage sanitation,
  heavy equipment cleaning, agricultural washdown, and industrial surface prep.
• Designed for continuous-duty hot water operation with slow-speed 1450-RPM performance for reduced
  mechanical stress, cooler running, and extended pump life.

Hot-Water-Optimized Design of WHW2115N

• Thermal-resistant seals and high-temperature valve components engineered to withstand hot water and
  detergent exposure over thousands of operating hours.
• Forged brass manifold maintains dimensional stability under repeated thermal expansion and contraction,
  preventing distortion and leaks.
• Ceramic plungers help dissipate heat and reduce friction, maintaining volumetric efficiency in hot-duty cycles.
• Capable of handling high inlet temperatures (up to approx. 185°F, application and configuration dependent)
  where hot water dramatically improves cleaning speed and reduces chemical use.

Construction & Durability

• Triplex plunger architecture with three solid ceramic plungers for smooth, low-pulsation output and
  reduced stress on hoses and accessories.
• Forged brass manifold delivers superior strength, corrosion resistance, and long-term sealing integrity.
• Oversized connecting rods and high-strength bearings maintain shaft alignment and absorb heavy loads
  during continuous-duty operation.
• Die-cast aluminum crankcase offers mechanical rigidity and enhanced heat dissipation for internal components.
• Stainless steel valves resist scaling, mineral buildup, and chemical attack in hot water and detergent service.
• Heavy-duty sealing system preserves compression and volumetric efficiency, even under high temperature and long run times.

Performance & Operation – WHW2115N

• Balanced 5.55 GPM / 2200 PSI duty point ideal for degreasing, rinsing, and high-volume washdown in hot-water systems.
• Slow-speed 1450-RPM operation reduces mechanical stress, vibration, and heat generation, extending pump and drive life.
• Crankshaft-driven design ensures smooth, quiet running with carefully balanced rotating components.
• Oil-bath lubrication continuously protects bearings and moving parts, stabilizing temperature and minimizing friction.
• Integrated sight glass and vented fill cap make oil checks and service quick and straightforward.
• Factory-tested for flow rate, pressure stability, and thermal performance to confirm reliable hot water operation.

Typical Applications

• Fleet maintenance: Hot water cleaning of trucks, buses, trailers, and heavy road equipment.
• Food & beverage sanitation: Washdown of processing lines, conveyors, and plant surfaces where heat and hygiene matter.
• Heavy equipment cleaning: Excavators, loaders, agricultural machinery, and mining equipment.
• Agricultural washdown: Barns, milking parlors, livestock areas, and equipment in high-soil environments.
• Industrial surface prep: Removal of oils, greases, and residues prior to coating, painting, or repair.
• Commercial & municipal wash bays: Hot-water systems in facilities that require frequent, high-efficiency cleaning.

Maintenance & Serviceability

• Straightforward routine care: Monitor oil level via sight glass, check inlet filters, and rinse out detergents after use.
• Easy seal and valve access for scheduled maintenance, reducing downtime and service labor.
• Flush-after-use practice helps prevent scaling, corrosion, and detergent residue buildup inside the pump.
• Heavy-duty ceramic plungers and brass manifold resist abrasive and thermal wear, extending service intervals.
• Balanced crankshaft and vibration-minimized design reduce long-term stress on bearings, seals, and drive couplings.
