HYD-RTX50WC Hydraulic Motor Pump

HYD-RTX50WC | Hydraulic Drive Washdown Unit | 13.2 GPM 2900 PSI | RTX50 Package

HYD-RTX50WC turns a truck’s hydraulic system into a serious washdown plant: an Annovi Reverberi RTX50 solid-shaft triplex pump producing 13.2 GPM (50 L/min) at up to 2900 PSI (200 bar), spun at 1450 RPM by a Sauer Danfoss hydraulic motor through the F50 flange, the whole assembly factory-aligned on mounting rails. Upfitters drop it onto a deck, run hydraulic and water plumbing, and the vehicle gains cleaning capability that would otherwise demand a dedicated 25-horsepower engine — with none of the fuel, noise, exhaust, or maintenance an engine brings to a work truck.

Support vehicles are where this unit earns its keep. Hydrovac and jetting support trucks rinsing tools, tanks, and booms between holes. Water trucks adding washdown duty to their tank capacity. Municipal and utility fleets that need to clean equipment at the job instead of hauling mud home. Agricultural operations washing planters, sprayers, and livestock trailers wherever they sit. The HYD-RTX50WC’s combination of fire-hose flow and commercial pressure handles all of it from the auxiliary hydraulics the vehicle already carries.

What Your Hydraulic Circuit Must Supply

Budget approximately 18.5 GPM (70 L/min) of continuous oil at 2,100–2,300 PSI working pressure — call it 25 hydraulic horsepower — for the full 13.2 GPM / 2900 PSI water duty point. That envelope matches standard-flow skid steer auxiliaries and well-specified truck hydraulic systems. The number that cannot be skipped: the Danfoss motor tops out at 2,320 PSI, while most vehicle circuits relieve at 3,000–3,500 PSI — install a relief that protects the motor at or below its ceiling before the first trigger pull. Return oil wants a short, generous line back to tank with filtration, and continuous washdown duty needs real oil cooling. Short on flow? The HYD-RTX50WC degrades gracefully — around 14 GPM of oil still yields roughly 10 GPM of water — though hitting full water pressure always requires full oil pressure at the motor. WSHPWR will verify your vehicle’s auxiliary specs against the requirement before you buy; call with flow, pressure, and relief setting.

Built for the Upfit

Everything about the package serves installation speed: the F50 flange fixes motor-to-pump alignment permanently at the factory, the rails bolt to deck or skid without fabrication, and the dual 1″ inlets and dual 1/2″ discharges give the plumber port options on both sides. There is no belt to guard, no coupler to gap, no alignment to check after the truck’s first thousand miles of washboard road. When service eventually calls, motor and pump separate at the flange independently — the repair path never requires pulling the whole unit.

RTX Platform Durability

Under the hood is AR’s 366-series industrial architecture: ceramic plungers that shrug off heat and abrasive water, a crankcase with sight-glass oil monitoring, and valves accessed through the head in place. The HYD-RTX50WC shares repair kits and procedures with every RTX-family unit, so fleets standardized on the platform stock one shelf of parts for all of it.

Installation & Operation Notes

Set the rails horizontal, confirm motor rotation before first start, and give the suction side respect: 13.2 GPM through restricted plumbing cavitates, and cavitation eats valves and plungers. Flooded suction from the tank, full-size lines, clean filtration. Fit an unloader against your working pressure, double-check the hydraulic relief against the motor’s 2,320 PSI limit, match nozzles to 13.2 GPM at target pressure, and cap speed at 1450 RPM. Winterize before the first hard freeze — a truck-mounted unit is the most exposed pump in the fleet.

Quality Assurance & Maintenance

Every HYD-RTX50WC ships factory-tested for flow, pressure stability, and vibration. Upkeep is the standard RTX schedule — crankcase oil changes, seal inspection, periodic valve checks with AR kits — and the balanced duty point keeps wear moderate on both sides of the pump.

HYD-RTX50WC Key Features & Applications

• Turns vehicle hydraulics into a 13.2 GPM / 2900 PSI washdown plant — no engine, fuel, or exhaust on deck.
• Factory-aligned package: AR RTX50 pump, Danfoss motor, F50 flange, and bolt-down rails.
• Runs on ~18.5 GPM of oil at 2,100–2,300 PSI (~25 hydraulic HP) — the standard-flow auxiliary envelope.
• Motor ceiling 2,320 PSI — a protecting relief on the vehicle circuit is mandatory.
• Ceramic plungers and in-place valve service on the shared RTX parts platform.
• Ideal for hydrovac and jetting support trucks, water trucks, municipal and utility fleets, and on-site agricultural washdown.
