HYD-RTX30.500P RTX30 Pump Motor Package | Direct Drive

HYD-RTX30.500P | UHP Hydraulic Drive Pump | 7250 PSI 7.9 GPM | 500 Bar Water Blasting

HYD-RTX30.500P brings Annovi Reverberi’s RTX 30.500 ultra-high-pressure platform to hydraulically powered blast systems: 7250 PSI (500 bar) working pressure at 7.9 GPM (30 L/min), turned at 1450 RPM by a direct-mounted hydraulic motor. At 500 bar, the water jet does work that pressure washing cannot — cutting coatings to bare metal, opening fouled exchanger tubes, milling laitance and failed surface off concrete — and this pump packages that capability for the trailers, containers, and plant cells where hydraulic power is the practical way to deliver 40+ horsepower to a wet environment.

Blast contractors and OEM system builders choose the hydraulic route for reasons an engine drive cannot match: the power source sits away from the operator, the pump cell stays quiet and fume-free, speed holds steady regardless of load, and the compact motor-on-pump package fits containment enclosures that would never swallow a diesel. The HYD-RTX30.500P is the wet end that architecture is built around.

Powering the HYD-RTX30.500P

AR’s factory pairing for this platform is a 64cc piston motor supplied with 102 L/min (26.9 GPM) of oil at 203 bar (2,944 PSI) — call it 46 hydraulic horsepower, continuously. Plan the power unit around that number: pump or PTO capacity with margin, reservoir sized for the duty cycle, return-line filtration, and a cooler specified for all-day blasting rather than intermittent triggering. Alternative motors work if the math works — target 1450 RPM via RPM ≈ 231 × hydraulic GPM ÷ displacement (in³), then check torque at your circuit pressure and cap the circuit with a relief set to protect the motor. WSHPWR will run the numbers with you: call with your power unit’s flow, pressure, and cooling capacity and we will confirm the motor spec before anything ships.

UHP Is a System, Not a Pump

At 500 bar the pump is only as safe as the weakest component downstream. Specify hose, lances, guns, nozzles, and relief hardware with genuine UHP ratings and proper margin — nothing from the 4000 PSI world belongs in this circuit. Filter the inlet water rigorously, because 500-bar orifices are small and a single grain of grit shows up as a pressure spike or a damaged seat. Train operators to UHP practice with the PPE to match. The HYD-RTX30.500P carries its share of the discipline in hardware: a 366-series frame and valve architecture engineered for the sustained load, ceramic plungers, and valve access serviceable in place so inspection habits are easy to keep.

Drive Architecture

The hollow 13T splined shaft accepts a male-splined SAE B hydraulic motor directly — the motor bolts to the F56 flange and the splines engage, with no coupler to align, no belt to tension, and no guard to fabricate. Pump and motor rotate on a single centerline, sparing bearings and seal packs the side loads that shorten life in offset drives, and either component comes off independently at the flange when service requires. The whole assembly stays compact enough for blast-trailer decks and containment cells measured in inches.

Installation & Operation Notes

Verify the motor spline before ordering — 13T SAE B for this pump; the 14T SAE C motors used on RTD-class equipment will not engage. Mount horizontally and confirm rotation at commissioning. Feed the 1″ inlets from a flooded, filtered supply: cavitation at this pressure class destroys valves and plungers faster than any other operating error. Install a certified safety relief in addition to primary regulation, pressure-test the complete assembly to UHP practice before first use, match nozzle orifices to 7.9 GPM at working pressure, and hold speed at or below 1450 RPM. Winterization is non-negotiable — freeze expansion inside a 500-bar head is a scrapped component, not a repair.

Quality Assurance & Maintenance

Every HYD-RTX30.500P ships factory-tested for flow, pressure stability, and vibration. Service follows AR’s RTX pattern on UHP-appropriate intervals: crankcase oil changes on schedule, seal inspection treated as a safety check rather than a courtesy, valve checks with AR repair kits, and a pressure test logged after every seal service. Fleet shops already running RTX-family equipment will find the parts and procedures familiar.

HYD-RTX30.500P Key Features & Applications

• Genuine 500-bar capability — 7.9 GPM at 7250 PSI on AR’s RTX 366-series frame.
• Direct hydraulic drive via hollow 13T spline and F56 flange — no coupler, belt, or alignment.
• Factory motor pairing published by AR: 64cc piston, 26.9 GPM at 2,944 PSI oil (~46 hydraulic HP).
• Quiet, fume-free, speed-stable power delivery for enclosed blast cells and trailers.
• Ceramic plungers with serviceable-in-place valve access for disciplined UHP maintenance.
• Ideal for coating and paint removal, surface preparation to bare substrate, concrete scarification, tube and heat-exchanger cleaning, and industrial water blasting systems.
