HYD-RTX85 | Hydraulic Motor Pump Package | 22.5 GPM 2200 PSI | RTX Series

HYD-RTX85 is the flow flagship of Annovi Reverberi’s RTX hydraulic drive family — an RTX85 solid-shaft triplex plunger pump rated at 22.5 GPM (85 L/min) and up to 2200 PSI (150 bar) at 1450 RPM, coupled to the strongest Sauer Danfoss motor in the package line through the F50 flange and delivered factory-aligned on mounting rails. Twenty-two and a half gallons a minute is the most water available in the standard RTX package format: past this point, AR’s catalog moves to the 1000 RPM RTD industrial frames at twice the weight and a different class of hydraulic supply.

That ceiling position defines its buyers: operations whose bottleneck is water on target. Hydrovac fleets rinsing tanks, booms, and tooling between holes without waiting. Aggregate, mining, and concrete plants flushing crushers, screens, mixers, and slump from equipment that never really stops. High-throughput wash bays clearing tractor-trailers at pace. Municipal and agricultural fleets where the mud is measured in inches. The HYD-RTX85 keeps 2200 PSI of commercial working pressure behind every one of those gallons.

Hydraulic Supply Requirements

Full 22.5 GPM at 2200 PSI performance calls for approximately 18.5 GPM (70 L/min) of continuous oil flow at working pressure approaching the Danfoss motor’s 3,265 PSI (225 bar) rating — roughly 32 to 35 hydraulic horsepower, the highest demand in the standard package family. This unit wants a strong host: high-flow skid steer auxiliaries at the top of their range, wheel loader circuits, and engineered truck hydraulic systems. Two verifications before ordering: that your circuit sustains the flow continuously (not just at spec-sheet peak), and that your relief protects the motor at or below 3,265 PSI. Route return oil short and unrestricted to tank with filtration, and size oil cooling for trigger-on hours. With less oil available the HYD-RTX85 runs proportionally slower — useful water still, at reduced rate — while full water pressure always requires full supply pressure at the motor. Call WSHPWR with your machine’s flow, pressure, and relief numbers and we will confirm the match first.

The Most Water Before the Platform Jump

Between the HYD-RTX85 and the next step up — the RTD 1000 RPM industrial class — sits a real decision: the RTD frames add flow and duty-cycle headroom, but at twice the mass, a bigger power bill, and dedicated-power-unit hydraulics. For fleets whose machines can host it, this package is the practical maximum: RTD-class rinse capacity from a 93.7-pound unit running on auxiliary hydraulics a strong machine already has. It out-rinses the RTX70 by 22% at identical pressure, and it means many operations never need the platform jump at all. WSHPWR stocks both sides of that line and will walk the duty-cycle math with you.

Direct-Drive Advantages

Motor and pump share one centerline through the F50 flange, with the rails preserving factory alignment through years of transport and deck vibration — no belts, pulleys, guards, or field alignment anywhere in the drive. Side loading on bearings and seals stays minimal, output holds steady regardless of host engine speed, and motor or pump dismounts independently at the flange when service calls. Installation is bolt-down, plumb, and wash.

RTX 366-Series Construction

The RTX frame carries ceramic plungers for heat and abrasion resistance, a crankcase with sight-glass oil monitoring, and valves accessed in place through the head — routine inspection without pulling the HYD-RTX85 from its rails. Repair kits and procedures interchange across the RTX family, so mixed fleets stock one shelf.

Installation & Operation Notes

Mount the rails horizontal and confirm motor rotation at commissioning. Treat suction as the critical path: 22.5 GPM is the highest inlet demand of any standard package, and any restriction cavitates — flooded supply, honest filtration, full-size lines into the dual 1″ inlets, every time. Fit an unloader against working pressure, verify the hydraulic relief against the motor’s 3,265 PSI ceiling, and size nozzles or spray bars to the full 22.5 GPM — orifices carried over from smaller machines will spike pressure and park the unloader in bypass. Hold 1450 RPM as the ceiling and winterize thoroughly before cold-weather storage.

Quality Assurance & Maintenance

Every HYD-RTX85 ships factory-tested for flow rate, pressure stability, and vibration. Maintenance follows the shared RTX schedule — crankcase oil changes, seal inspection, in-place valve checks with AR repair kits — and the moderate 2200 PSI duty point keeps wear rates gentle even at maximum family flow.

HYD-RTX85 Key Features & Applications

• 22.5 GPM at 2200 PSI, 1450 RPM — the most water in the standard RTX package format.
• Strongest Danfoss in the package line: 18.5 GPM at up to 3,265 PSI hydraulic supply (~32–35 hydraulic HP).
• Complete factory-aligned package: AR RTX85 pump, Danfoss motor, F50 flange, and mounting rails.
• 22% more rinse capacity than the RTX70 at identical pressure — often the alternative to an RTD platform jump.
• Ceramic plungers and in-place valve service on the shared RTX parts platform.
• Ideal for hydrovac fleet support, aggregate and concrete plant washdown, high-throughput wash bays, municipal fleets, and heavy agricultural cleaning.
