AR XHW Hot Water Pumps

When cold water isn’t enough, the AR XHW Hot Water Pump Series delivers the power, reliability, and heat resistance needed for the toughest cleaning jobs. Designed by Annovi Reverberi (AR)—a name trusted worldwide in pump technology—the XHW family is engineered to perform in high-temperature environments where grease, oil, and stubborn residues demand more than just cold water.
With continuous operation at inlet temperatures up to 180°F, these pumps provide the perfect combination of high pressure, moderate flow, and durability. They are a proven choice for industries ranging from food processing and farming to fleet maintenance, restaurants, and industrial workshops.

Why Hot Water Pumps Matter
Hot water pressure washing has a significant edge over cold water:

Breaks down grease and oil faster.
Kills bacteria in food and agriculture environments.
Cuts cleaning time by loosening stubborn residues.
Reduces detergent use, lowering costs and environmental impact.

But not every pump is built to handle hot water. Standard cold-water pumps often fail prematurely when exposed to elevated temperatures. The AR XHW Series, however, is purpose-built with materials and design features that ensure reliable long-term performance in hot water applications.

Key Engineering Features
Each XHW model is precision-engineered with components designed to withstand high temperatures and continuous-duty operation:

Maximum Inlet Temperature: 180°F for true hot water cleaning.
Pump Head: Nickel-plated brass for corrosion resistance.
Connecting Rods: Aluminum, providing strength and balanced weight.
Plungers: Stainless steel, built for long service life under abrasive conditions.
Sealing System: Specialized water and oil seals rated for sustained heat.
Crankcase: 32 oz. oil capacity for consistent cooling and lubrication.
Ports: 3/4” F Inlet, 3/8” F Discharge for reliable hose and system connections.

Just like AR’s larger industrial triplex pumps, the XHW line is fully rebuildable, with readily available service kits to extend lifespan and reduce cost of ownership.

Model Lineup
The XHW Series includes two primary models, offering flexibility for different system sizes and cleaning needs.
XHW08.15N

Flow: 2.1 GPM
Pressure: 2,200 PSI
Horsepower (ebhp): 3.2 HP
Speed: 1450 RPM
Bore/Stroke: 14 mm × 15 mm
Weight: ~10.6 lbs

This compact model is ideal for light-to-medium duty hot water systems. Applications include:

Commercial kitchens
Compact cabinet washers
Small workshops
Facilities with limited space but high-pressure needs

XHW11.17N

Flow: 3.0 GPM
Pressure: 2,500 PSI
Horsepower (ebhp): 5.0 HP
Speed: 1450 RPM
Bore/Stroke: 14 mm × 15 mm
Weight: ~15.4 lbs

The XHW11.17N is the workhorse of the lineup, offering higher flow and pressure for continuous-duty use. Applications include:

Truck wash stations
Food and beverage processing plants
Agricultural sanitation systems
Industrial equipment cleaning

With more flow and horsepower, this model is perfect for contractors and facility managers who need consistent hot water performance on larger surfaces and heavier soils.

Replacement Parts & Service Kits
One of the biggest advantages of AR pumps is their serviceability. The XHW series has dedicated rebuild kits that make maintenance straightforward:

Valves (AR2331): Stainless steel kits for proper flow and pressure.
Pistons (AR2544): Hard-coated for long life in high-temp environments.
Water Seals (AR2332): Specialized seals rated for 180°F.
Oil Seals (AR2786): Protect the crankcase against heat-related wear.
Support Rings (AR2740): Reinforcement parts to maintain pump performance.

This ensures that operators can keep pumps running for years without the downtime or expense of replacing entire units.

Applications for the XHW Pump Series
The AR XHW line is trusted in industries where hot water is essential:

Food & Beverage Processing – Sanitation of floors, equipment, and washdown stations; compliance with USDA and FDA hygiene standards.
Fleet & Transportation – Degreasing truck bays, removing winter salt, and cleaning diesel residue from vehicles.
Agriculture & Farming – Hot water sanitation in hog barns, dairy operations, and for cleaning tractors and implements.
Hospitality & Restaurants – Grease and oil removal in kitchens, hoods, and duct systems.
Manufacturing & Workshops – Cleaning machinery coated with oil, cutting fluids, or industrial grime.

These pumps provide heat, pressure, and reliability where cold water systems fall short.

Why Choose the XHW Series?
There are many triplex pumps on the market, but the XHW Series stands apart with features tailored for hot water performance:

Compact but Powerful – 2.1–3.0 GPM at 2,200–2,500 PSI covers a wide range of cleaning needs.
Hot Water Ready – Factory-rated for continuous operation with 180°F inlet water.
Durable Construction – Nickel-plated brass, stainless steel plungers, and high-grade seals.
Service Friendly – Easy access to rebuild kits lowers long-term costs.
Proven AR Engineering – Backed by Italian design and worldwide parts availability.

For contractors, municipalities, and industrial users, the XHW series is the ideal balance of size, performance, and durability.

The Bottom Line
The AR XHW Hot Water Pump Series is designed for professionals who need more than cold water cleaning. With flow rates between 2.1 and 3.0 GPM and pressures from 2,200 to 2,500 PSI, these pumps deliver powerful cleaning action with the added advantage of hot water capability.
Whether you’re operating a restaurant sanitation system, farm wash bay, fleet wash station, or industrial plant, AR’s XHW line gives you:
