HYD-RTX70 | Hydraulic Motor Pump Package | 18.5 GPM 2200 PSI | RTX Series

HYD-RTX70 is the volume mover of Annovi Reverberi’s RTX hydraulic drive family — an RTX70 solid-shaft triplex plunger pump rated at 18.5 GPM (70 L/min) and up to 2200 PSI (150 bar) at 1450 RPM, coupled to a Sauer Danfoss hydraulic motor through the F50 flange and delivered on rigid mounting rails as one factory-aligned drive unit. When the job is measured in surface covered, tonnage rinsed, or dust knocked down — rather than coatings stripped — flow is the spec that matters, and 18.5 gallons a minute is where washdown starts feeling like a fire hose.

That volume, powered silently off a machine’s hydraulic circuit, serves the work that big flow was made for: washing down crushers, screens, and conveyors in aggregate and mining operations; rinsing mixer drums, tankers, and ag equipment where mud comes off in sheets; dust suppression on demolition and material handling sites; wash bays and fleet yards clearing trucks at pace; and hydrovac support duty where tools and tanks need rinsing all shift. The HYD-RTX70 delivers 2200 PSI of genuine commercial pressure behind every one of those gallons.

Hydraulic Supply Requirements

Full 18.5 GPM at 2200 PSI performance calls for approximately 18.5 GPM (70 L/min) of continuous oil flow at working pressure up to the Danfoss motor’s 2,610 PSI (180 bar) rating — roughly 28 hydraulic horsepower. That envelope suits high-flow skid steer auxiliaries, truck hydraulic systems, and machine circuits on the stronger end of standard; verify both your continuous flow and your relief setting, since a relief protecting the motor at or below 2,610 PSI is mandatory on circuits that relieve higher. 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 oil available, the HYD-RTX70 runs proportionally slower — 14 GPM of oil still delivers roughly 14 GPM of water — while full water pressure always requires full supply 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.

Flow Does This Work

Cleaning power multiplies flow and pressure, but the jobs split by which one leads. Rinsing a mixer drum, flushing a crusher deck, or suppressing dust is a volume problem: more gallons per minute means more material moved per pass and fewer passes per job. At 18.5 GPM, the HYD-RTX70 finishes rinse work in roughly 60% of the time a 13 GPM unit needs and less than half the time of the 8 GPM class — and on a wash bay or support truck billing by the vehicle or the hole, those minutes are the product. Buyers whose work leans toward stripping and cutting should look instead at the pressure-led end of the family; WSHPWR stocks both and will match the duty point to the actual work.

Direct-Drive Advantages

Motor and pump share one centerline through the F50 flange — no belts, pulleys, guards, or field alignment — and the factory rails hold the assembly true through transport and years of deck vibration. Side loading on bearings and seals stays minimal, output is independent of the host machine’s engine speed, and motor or pump dismounts independently at the flange when service calls. The package installs as one unit: bolt down, plumb, wash.

RTX 366-Series Construction

The RTX frame brings ceramic plungers, a robust crankcase with sight-glass oil monitoring, and valves accessed in place through the head — no dismounting the HYD-RTX70 from its rails for routine inspection. Repair kits and procedures are shared across the RTX family, keeping one parts shelf serving mixed fleets.

Installation & Operation Notes

Mount the rails horizontal and confirm motor rotation at commissioning. Respect the suction math: 18.5 GPM is the highest inlet demand in the standard package family, and restricted plumbing means cavitation — feed the dual 1″ inlets from a flooded, filtered supply through full-size lines. Fit an unloader against your working pressure, verify the hydraulic relief against the motor’s 2,610 PSI ceiling, size nozzle orifices to the 18.5 GPM duty point — undersized nozzles from smaller machines will spike pressure and drive constant bypass — and never exceed 1450 RPM. Winterize thoroughly before cold-weather storage.

Quality Assurance & Maintenance

Every HYD-RTX70 ships factory-tested for flow rate, pressure stability, and vibration. Maintenance follows the RTX schedule — crankcase oil changes, seal inspection, periodic valve checks with AR repair kits — and the moderate 2200 PSI duty point keeps seal and valve wear on the gentle side of the family curve.

HYD-RTX70 Key Features & Applications

• 18.5 GPM at 2200 PSI, 1450 RPM — the volume workhorse of the RTX package family.
• Complete drive unit: AR RTX70 pump, Sauer Danfoss motor, F50 flange, and mounting rails, factory-aligned.
• Requires approximately 18.5 GPM of hydraulic flow at up to 2,610 PSI (~28 hydraulic HP); protecting relief mandatory.
• Rinse work finishes in roughly 60% of the time a 13 GPM unit needs.
• Ceramic plungers and in-place valve service on the shared RTX parts platform.
• Ideal for aggregate and mining washdown, mixer and tanker rinsing, dust suppression, wash bays and fleet yards, agricultural cleaning, and hydrovac support duty.
