HYD-XWL50.09 Hydraulic Motor Pump | XWL50.09 Series

HYD-XWL50.09 | Hydraulic Motor Pump Drive Unit | 13.2 GPM 1300 PSI | High Flow Rinse

HYD-XWL50.09 solves a problem most of this category ignores: moving serious water gently. Built on Annovi Reverberi’s XWL frame, this hydraulic drive unit delivers 13.2 GPM (50 L/min) at up to 1300 PSI (90 bar) at 1450 RPM per AR North America’s published specifications — fire-hose rinse volume at a working pressure that painted panels, vinyl graphics, gaskets, and delicate surfaces tolerate all day. Where the rest of the range asks how hard water can hit, the HYD-XWL50.09 asks how much water can flow without damage — and answers with the highest flow-to-pressure ratio in AR’s hydraulic line.

That balance targets the washing nobody should do at 3000 PSI: fleet and transit rinsing over wraps, decals, and lettering; bus and trailer wash lanes; agricultural rinse-down where high pressure drives water past seals; livestock and barn washdown; produce and food-plant rinse duty; solar array and signage cleaning; and high-volume rinse arches and manifold systems. Wherever the failure mode is “the washer damaged it,” this drive unit is the correct specification.

Hydraulic Supply Requirements

Full 13.2 GPM output runs on modest power for its water volume: approximately 14 hydraulic horsepower. AR’s published pairings for the XWL 50.09 platform are a 22cc gear motor drawing 37 L/min (9.8 GPM) of oil at 170 bar (2,465 PSI) — matching the drive unit’s 9.5 GPM-class motor — or a 17cc gear motor drawing 27 L/min (7.1 GPM) at 231 bar (3,350 PSI) for flow-tight circuits. Either envelope fits standard skid steer auxiliaries, tractor remotes, and truck systems without strain; this is one of the easiest big-water units in the range to power. Protect the motor with a relief at its rating, run return oil short and filtered to tank, and provide cooling for continuous rinse duty. Call WSHPWR with your machine’s flow and pressure and we will confirm the pairing.

Why Low Pressure Is the Feature

Pressure damage is a real cost: stripped decals and wraps re-applied at hundreds of dollars a panel, water driven past shaft seals into bearings, chipped paint that becomes a corrosion claim, produce bruised and surfaces etched. The industry answer is usually “stand farther back with a big machine” — imprecise and operator-dependent. The HYD-XWL50.09 makes gentleness a specification instead of a technique: 1300 PSI at the nozzle is rinse-safe on the surfaces above by design, while 13.2 GPM supplies the sheeting action that actually carries soil away. Rinsing is a volume process; this unit is built like it.

Direct-Drive Simplicity

The gear motor mounts to the pump through AR’s F38 close-couple interface — one centerline, no belts, pulleys, guards, or field alignment, minimal side loading on bearings and seals, and output independent of the host machine’s engine speed. Motor or pump dismounts independently at the flange for service, and the whole unit installs as a bolt-down package on trucks, wash lanes, and skids.

194-Series Construction

The XWL frame carries a brass head with one-piece ceramic plungers, a die-cast crankcase with oil monitoring, and valve access through the head for inspection without dismounting the HYD-XWL50.09 from its mount. The moderate 90-bar duty point is the gentlest continuous service a 194-series wet end can see — seal and valve intervals stretch accordingly, and AR repair kits keep the eventual service path standard.

Installation & Operation Notes

Mount horizontally and confirm motor rotation at commissioning. Respect the inlet: 13.2 GPM through the 3/4″ port demands flooded, filtered, unrestricted suction plumbing — buffer-tank feed is good practice at this flow. Pair the discharge with an unloader set against working pressure, and size nozzles, arches, or manifolds to the full 13.2 GPM — undersized orifices raise pressure and defeat the surface-safe purpose. Hold 1450 RPM as the ceiling and winterize before cold-weather storage.

Quality Assurance & Maintenance

Every HYD-XWL50.09 ships factory-tested for flow rate, pressure stability, and vibration. Maintenance follows AR’s standard schedule — crankcase oil changes, seal inspection, periodic valve checks with AR repair kits — and the low-pressure duty point makes this among the longest-interval pumps in the entire hydraulic range.

HYD-XWL50.09 Key Features & Applications

• 13.2 GPM at 1300 PSI, 1450 RPM — the highest flow-to-pressure ratio in AR’s hydraulic line.
• Surface-safe by specification: rinse volume that protects wraps, decals, paint, seals, and produce.
• Complete drive unit: XWL pump close-coupled to a gear motor on the F38 interface.
• Runs on ~9.8 GPM of oil (~14 hydraulic HP) — one of the easiest big-water units to power.
• Gentle duty point stretches seal and valve intervals; standard AR repair kits when service comes.
• Ideal for fleet and transit rinse lanes, wrapped and lettered vehicles, agricultural and livestock washdown, food-plant rinse duty, solar and signage cleaning, and rinse-arch systems.
