HYD-RTX30.500A Hydraulic Motor Pump | RTX30 Series

HYD-RTX30.500A | Ultra High Pressure Hydraulic Motor Pump | 7.9 GPM 7250 PSI

HYD-RTX30.500A is the ultra-high-pressure member of Annovi Reverberi’s RTX hydraulic drive family — a 366-series triplex plunger pump delivering 7.9 GPM (30 L/min) at up to 7250 PSI (500 bar) at 1450 RPM, built for direct hydraulic drive. This is the pressure class where water stops cleaning and starts cutting: surface preparation to bare substrate, coating and paint removal, concrete scarification and laitance removal, tube and heat-exchanger cleaning, and industrial blasting duty that conventional 3000 PSI-class washers cannot touch.

Hydraulic drive is the natural power source at this pressure. The motor delivers smooth, high-torque rotation without the vibration and footprint of an engine drive, and the HYD-RTX30.500A integrates cleanly into blast trailers, containerized units, and plant installations where hydraulic power already exists — or where a dedicated power unit beats housing a 40+ HP engine next to the operator.

Hydraulic Supply Requirements

Annovi Reverberi’s published pairing for the RTX 30.500 platform is a piston 64cc motor drawing 102 L/min (26.9 GPM) of oil at 203 bar (2,944 PSI) — roughly 46 hydraulic horsepower delivered continuously. That magnitude comes from a dedicated hydraulic power unit or a truck’s purpose-built system, not an auxiliary circuit. If you are specifying a different motor, size displacement to reach 1450 RPM at your available flow — RPM ≈ 231 × hydraulic GPM ÷ displacement (in³) — verify torque at working pressure, protect the motor with a correctly set relief, and engineer reservoir capacity, return filtration, and oil cooling for continuous duty at this power level. Call WSHPWR with your system’s flow, pressure, and cooling details and we will spec the motor and confirm the match before you commit.

Engineering for 7250 PSI

Ultra high pressure is a system discipline, not just a pump rating. Every downstream component — hose, fittings, gun, lance, nozzles, relief — must carry a genuine UHP rating for the working pressure with appropriate safety margin; 4000 PSI-class hardware has no place anywhere in the circuit. Nozzle orifices at this duty point are small and unforgiving of debris, so inlet filtration matters doubly, and operators need UHP-specific training and PPE. The HYD-RTX30.500A holds its side of that bargain with a 366-series frame engineered for the load: ceramic plungers, a pressure-rated head and valve architecture, and the same serviceable-in-place valve access that keeps the rest of the RTX family field-maintainable.

Direct-Drive Advantages

The HYD-RTX30.500A’s hollow 13T splined shaft slides directly onto a male-splined SAE B hydraulic motor — no coupler, no belt, no alignment procedure. Motor and pump share one centerline inside the rigid flange interface, protecting bearings and seal packs from side loading while keeping the installed package compact enough for trailers and containment cells. Cleaning performance stays independent of host engine speed, and either component swaps independently at the flange when service calls for it.

Installation & Operation Notes

Confirm your hydraulic motor’s spline count and mount before ordering — this pump takes a 13T SAE B motor; 14T SAE C motors from RTD-class systems will not interchange. Mount horizontally, verify motor rotation at commissioning, and feed the 1″ inlets from a flooded, filtered supply — cavitation at 7250 PSI destroys valves and plungers faster than at any lower pressure class. Fit a certified safety relief in addition to the regulation device, pressure-test the complete circuit per UHP practice before first operation, size nozzles to the 7.9 GPM duty point, and never operate above 1450 RPM. Winterize thoroughly; freeze damage at this wall thickness is not a repairable event.

Quality Assurance & Maintenance

Every HYD-RTX30.500A is factory-tested for flow rate, pressure stability, and vibration before shipment. Maintenance follows the RTX pattern — scheduled crankcase oil changes, seal inspection, and valve checks with AR repair kits — on intervals appropriate to UHP duty, where seal condition is a safety item as much as a performance item. Log hours and pressure-test after every seal service.
