HYD-RTX50 Hydraulic Motor Pump | RTX50 Series

HYD-RTX50 | Hydraulic Motor Pump Package | 13.2 GPM 2900 PSI | RTX Series

HYD-RTX50 is the balanced flagship of Annovi Reverberi’s RTX hydraulic drive family — an RTX50 solid-shaft triplex plunger pump rated at 13.2 GPM (50 L/min) and up to 2900 PSI (200 bar) at 1450 RPM, coupled to a Sauer Danfoss hydraulic motor through the F50 flange and delivered on rigid mounting rails as one aligned, ready-to-plumb drive unit. Where its siblings specialize — the RTX30 class trading flow for cutting pressure, the RTX70 and RTX85 trading pressure for volume — the HYD-RTX50 carries serious numbers on both sides at once, which is why it anchors so many hydrovac support systems, municipal washdown trucks, and heavy equipment cleaning rigs.

Thirteen gallons a minute rinses like a fire hose; 2900 PSI strips like a pressure washer twice its size. Together they cover the widest span of real work in the family: mud and clay off excavators and undercarriages, feed and manure washdown in agriculture, street and fleet equipment cleaning, jetting support, and dust suppression — all powered from the hydraulic circuit your machine already has, with no engine, fuel, or belts anywhere in the drive.

Hydraulic Supply Requirements

Full 13.2 GPM at 2900 PSI performance asks for approximately 18.5 GPM (70 L/min) of continuous oil flow at a working pressure around 2,100–2,300 PSI — roughly 25 hydraulic horsepower — which is exactly the envelope of a standard-flow skid steer auxiliary circuit or a well-built truck hydraulic system. One caution matters more than any other on the HYD-RTX50: the Danfoss motor’s ceiling is 2,320 PSI, and most machine circuits relieve at 3,000–3,500 PSI, so a relief protecting the motor at or below 2,320 PSI is mandatory — do not connect this package to an unregulated high-pressure circuit. Keep the return line short and low-restriction back to tank, specify return filtration, and provide oil cooling for continuous trigger-on duty. With less flow available, the HYD-RTX50 runs proportionally slower — 14 GPM of oil yields roughly 10 GPM of water — while reaching full water pressure still requires full oil pressure at the motor. Call WSHPWR with your machine’s auxiliary flow, pressure, and relief setting and we will confirm the match before you order.

Direct-Drive Advantages

Motor and pump share one centerline through the F50 flange interface — no belts, pulleys, guards, or field alignment — with the factory rails holding the assembly true through transport and daily service. Side loading on bearings and seals stays minimal, cleaning performance holds steady regardless of host engine speed, and either component swaps independently at the flange when service calls for it. The complete HYD-RTX50 package drops onto a truck deck, skid, or trailer as one unit, cutting installation to plumbing and hose runs.

RTX 366-Series Construction

The RTX frame is AR’s industrial mid-platform: ceramic plungers for heat dissipation and abrasion resistance, a robust crankcase with oil sight glass, and valve access serviceable in place so inspection and replacement happen without dismounting the HYD-RTX50 from its rails. Repair kits and procedures are shared across the RTX family, keeping the parts shelf simple for fleets running mixed RTX equipment.

Installation & Operation Notes

Mount the rail assembly horizontally and confirm motor rotation at commissioning. Feed the 1″ inlets from a flooded, filtered supply — at 13.2 GPM, restricted suction plumbing invites cavitation that destroys valves and plungers. Pair the discharge with a properly sized unloader set against your working pressure, verify the hydraulic-side relief against the motor’s 2,320 PSI ceiling before first start, size nozzle orifices to the 13.2 GPM duty point, and never operate above 1450 RPM. Winterize thoroughly before cold-weather storage.

Quality Assurance & Maintenance

Every HYD-RTX50 ships factory-tested for flow rate, pressure stability, and vibration. Maintenance follows the RTX pattern — scheduled crankcase oil changes, seal inspection, and periodic valve checks with AR repair kits — and the balanced duty point keeps wear rates moderate on both the pressure and flow sides of the equation.

HYD-RTX50 Key Features & Applications

• 13.2 GPM at 2900 PSI, 1450 RPM — the flow-and-pressure all-rounder of the RTX package family.
• Complete drive unit: AR RTX50 pump, Sauer Danfoss motor, F50 flange, and mounting rails, pre-aligned.
• Requires approximately 18.5 GPM of hydraulic flow at ~2,100–2,300 PSI — a standard-flow skid steer envelope.
• Motor rated 2,320 PSI maximum — a protecting relief on the hydraulic circuit is mandatory.
• Ceramic plungers and serviceable-in-place valves on AR’s 366-series industrial frame.
• Ideal for hydrovac support, municipal and fleet washdown, heavy equipment cleaning, agricultural washdown, jetting support, and dust suppression.
