HYD-RTX50.300P RTX50 Pump Motor Package | Direct Drive

HYD-RTX50.300P | Hydraulic Drive Pump | 13.2 GPM 4350 PSI | 300 Bar RTX

HYD-RTX50.300P puts high flow and cutting-class pressure in one compact hydraulic drive unit: Annovi Reverberi’s RTX 50.300 triplex plunger pump, rated at 13.2 GPM (50 L/min) and up to 4350 PSI (300 bar) at 1450 RPM, with AR’s published 38 HP power rating and direct hydraulic drive via a hollow 13-tooth splined shaft. Few pumps carry this duty point at this size — roughly 72 pounds on AR’s 366-series frame — which makes it the choice where hydro-excavation-class performance has to fit a compact skid, a crowded truck deck, or a weight budget that a 143-pound industrial frame would blow.

Thirteen gallons a minute moves spoil, flushes lines, and rinses acreage; 4350 PSI cuts compacted soil, strips coatings, and breaks baked material loose. The HYD-RTX50.300P delivers both simultaneously for compact hydrovac and potholing units, trailer jetters, heavy equipment stripping rigs, and OEM systems where the spec sheet demands numbers the standard 2900 PSI RTX packages cannot reach.

Hydraulic Supply Requirements

Annovi Reverberi publishes two factory motor pairings for the RTX 50.300 platform, both landing near 46 hydraulic horsepower: a gear 90cc motor drawing 142 L/min (37.5 GPM) of oil at 146 bar (2,117 PSI) — the fit for high-flow, moderate-pressure hydraulic systems — or a piston 64cc motor drawing 102 L/min (26.9 GPM) at 203 bar (2,944 PSI) for circuits with less flow and more pressure headroom. Either way this is dedicated-power territory: a purpose-built power unit or a truck’s engineered hydraulic system, not an auxiliary circuit. For any other motor, target 1450 RPM via RPM ≈ 231 × hydraulic GPM ÷ displacement (in³), verify torque at working pressure, cap the circuit with a relief protecting the motor, and engineer reservoir, return filtration, and cooling for continuous duty. Call WSHPWR with your system’s flow, pressure, and cooling details and we will spec the motor and confirm the match.

Compact Frame, Industrial Numbers

The natural comparison is AR’s RTD 80.300 class, which trades up to 21 GPM at the same 300 bar on a 1000 RPM frame at twice the weight. The HYD-RTX50.300P is the answer when the build cannot carry that: half the mass, a tighter envelope, and the same working pressure, at 13.2 GPM and 1450 RPM. Compact potholing units, trailer-mounted systems, and weight-rated truck bodies get genuine 300-bar capability without surrendering the payload or deck space the big frame demands. Fleets running both classes share the same hydraulic design discipline — only the duty-cycle math differs.

Direct-Drive Architecture

The hollow 13T splined shaft accepts a male-splined SAE B hydraulic motor directly at the F56 flange — no coupler, no belt, no field alignment. Motor and pump rotate on one centerline, sparing bearings and seal packs from side loading, and either component dismounts independently at the flange when service requires. The result installs as one tight package and stays aligned for its service life.

Installation & Operation Notes

Verify motor spline and mount before ordering — 13T SAE B for this pump; 14T SAE C motors from RTD-class systems will not engage. Mount horizontally, confirm rotation at commissioning, and feed the 1″ inlets from a flooded, filtered supply: at 13.2 GPM and this pressure, suction restriction converts directly into cavitation damage. Fit an unloader plus a safety relief rated for the working pressure, keep every downstream component — hose, gun, lance, nozzles — rated for 4350 PSI with margin, size orifices to the 13.2 GPM duty point, and hold speed at or below 1450 RPM. Winterize thoroughly before cold-weather storage.

Quality Assurance & Maintenance

Every HYD-RTX50.300P ships factory-tested for flow rate, pressure stability, and vibration. Service follows the RTX family pattern — scheduled crankcase oil changes, seal inspection, and valve checks with AR repair kits, all serviceable in place — with seal condition watched closely at the 300-bar duty point.

HYD-RTX50.300P Key Features & Applications

• 13.2 GPM at 4350 PSI (300 bar), 1450 RPM — industrial numbers on a 72-pound compact frame.
• AR-published 38 HP rating with two factory motor pairings: gear 90cc (37.5 GPM oil) or piston 64cc (26.9 GPM oil), ~46 hydraulic HP either way.
• Hollow 13T splined shaft direct-drives from an SAE B hydraulic motor — no coupler or alignment.
• Half the weight of the 300-bar RTD class — for compact skids, trailers, and weight-limited builds.
• Ceramic plungers and serviceable-in-place valves on AR’s 366-series frame.
• Ideal for compact hydro-excavation and potholing units, trailer jetters, coating and surface stripping, and OEM high-pressure systems with tight envelopes.
