HYD-RTX70WC Hydraulic Motor Pump | RTX70WC Series

HYD-RTX70WC | Hydraulic Washdown & Dust Suppression Unit | 18.5 GPM 2200 PSI

HYD-RTX70WC delivers site-scale water capacity from a machine’s hydraulic circuit: an Annovi Reverberi RTX70 solid-shaft triplex pump producing 18.5 GPM (70 L/min) at up to 2200 PSI (150 bar), driven at 1450 RPM by a Sauer Danfoss hydraulic motor through the F50 flange, factory-aligned on mounting rails. No engine, no fuel, no exhaust — just 18.5 gallons a minute of working water wherever the host machine’s hydraulics go, which is exactly what dust control, high-throughput washdown, and site sanitation operations run on.

Dust suppression alone justifies the unit on many sites. Respirable silica rules have made water-at-the-source a compliance matter on demolition, crushing, cutting, and material-handling operations — and effective suppression is a volume game, wetting material continuously rather than misting it occasionally. The HYD-RTX70WC sustains that duty all shift from a loader, excavator, or water truck’s hydraulic system, then converts to washdown mode for equipment, decks, and haul roads with 2200 PSI behind the same flow.

What the Host Machine Must Supply

Budget approximately 18.5 GPM (70 L/min) of continuous hydraulic oil at working pressure up to the Danfoss motor’s 2,610 PSI (180 bar) rating — about 28 hydraulic horsepower for the full water duty point. High-flow skid steer auxiliaries, wheel loader circuits, and truck hydraulic systems carry this; standard compact-machine circuits may run the unit at reduced output, which for suppression duty is often still useful water. The non-negotiable: protect the Danfoss with a relief at or below 2,610 PSI on any circuit that relieves higher. Route return oil short and unrestricted to tank with filtration, and provide real oil cooling — suppression and washdown are trigger-on-for-hours duties, not bursts. WSHPWR verifies host-machine specs against the requirement daily; call with your flow, pressure, and relief numbers before ordering.

Volume Duty, All Shift

Continuous-duty flow work is its own discipline. Dust suppression may run the HYD-RTX70WC hours at a time; wash bays cycle it truck after truck. The package is built for it — ceramic plungers managing heat, a 366-series crankcase sized for sustained load, and the moderate 2200 PSI duty point keeping seal and valve wear on the gentle end — but the installation must match: oil cooling sized for hours not minutes, suction plumbing that never starves 18.5 GPM, and nozzle or spray-bar orifices sized to the full flow so the unloader isn’t living in bypass. Set up correctly, this duty profile is among the kindest a high-pressure pump can run.

One Unit, Two Jobs

Sites that need suppression usually need washdown, and vice versa. Plumb the HYD-RTX70WC with a selector or quick-disconnect between a spray-bar circuit and a gun-and-wand circuit and one hydraulic package covers both: wet the crusher feed through the morning, rinse the excavator and the haul road at day’s end. That dual duty is the economic case against dedicated single-purpose units — one pump, one motor, one maintenance schedule, both compliance and cleanliness handled.

Package Simplicity

Motor and pump share one centerline through the F50 flange with the rails holding factory alignment through years of deck vibration — no belts, couplers, guards, or field alignment, and independent motor/pump service at the flange. Installation is bolt-down, plumb, and run.

Installation & Operation Notes

Mount the rails horizontal and confirm motor rotation at commissioning. Feed the dual 1″ inlets from a flooded, filtered supply through full-size lines — 18.5 GPM forgives no suction restriction, and suppression water sources (tanks, ponds) demand honest filtration. Fit an unloader against working pressure, verify the hydraulic relief against the 2,610 PSI motor ceiling, size spray bars or nozzles to 18.5 GPM, hold 1450 RPM, and winterize thoroughly — suppression units parked outdoors are the fleet’s most freeze-exposed equipment.

Quality Assurance & Maintenance

Every HYD-RTX70WC ships factory-tested for flow rate, pressure stability, and vibration. Maintenance runs the shared RTX schedule — crankcase oil changes, seal inspection, in-place valve checks with common AR repair kits — with filtration checks added when drawing from tanks or open sources.

HYD-RTX70WC Key Features & Applications

• 18.5 GPM at 2200 PSI, 1450 RPM — site-scale water from the host machine’s hydraulic circuit.
• Sustains continuous dust-suppression duty for silica-compliance water-at-the-source programs.
• Complete factory-aligned package: AR RTX70 pump, Danfoss motor, F50 flange, mounting rails.
• Requires ~18.5 GPM of oil at up to 2,610 PSI (~28 hydraulic HP); protecting relief mandatory.
• Dual-duty economics: one unit plumbs to both spray-bar suppression and gun-and-wand washdown.
• Ideal for crushing and screening plants, demolition dust control, wash bays, haul-road and equipment washdown, and water-truck upfits.
