HYD-RTX85-DD Hydraulic Motor Pump | 22.5 GPM 3000 PSI

HYD-RTX85-DD

• HYD-RTX85-DD is a compact, belt-free hydraulic drive package that couples a low-speed/high-torque (LSHT) hydraulic motor directly to the Annovi Reverberi RTX85 triplex plunger pump.
• Rigid, alignment-stable base delivers big-machine cleaning power with smooth, controllable torque in a footprint that fits trailers, service trucks, vans, and plant carts.
• Water end is selected for roughly 22.5 GPM (≈85 L/min) at 3000 PSI (≈207 bar) near 1450 RPM for multi-gun or large-tool washdown while keeping RPM modest for seal and bearing life.
• Direct-coupled layout eliminates belts and bulky guards, reduces vibration and alignment drift, and minimizes side loading on bearings and seal packs so the system runs cooler and lasts longer.
• Technician-friendly layout with clear access to the coupling, easy-view oil sight glass, vented dipstick, and key fasteners for quick single-tech preventive maintenance.

Hydraulic Motor & Circuit

• Uses a HYD-RTX85-DD displacement-matched LSHT gerotor/geroler-type hydraulic motor (manufacturer may vary) sized to reach the target pump RPM and torque at pressure.
• Integrates into standard mobile or plant hydraulic circuits via pressure and return ports typically specified at SAE-12 (3/4″ ORB).
• Auxiliary case-drain port commonly SAE-8 (1/2″ ORB) when required by the chosen motor build.
• Observe A/B port orientation for correct rotation; route the case drain above reservoir oil level to prevent aeration.
• Size hoses generously and respect bend radii to avoid restriction and heat buildup.
• Protect the circuit with upstream relief valves appropriate for the 3000-PSI duty class.
• Specify 10–25 μm return filtration with an adequate β-rating, and size the reservoir for heat rejection (practical rule is 2–3× total system flow).
• Add an oil cooler for hot climates, prolonged bypass, or continuous-duty operation.

Water-Side Plumbing

• RTX85 manifolds HYD-RTX85-DD are typically ported 1-1/4″ female BSPP inlet and 1/2″ female BSPP discharge; adapters to NPT are readily available.
• Keep the suction run short, straight, and oversize to protect volumetric efficiency and prevent cavitation.
• Add a coarse inlet strainer and use anti-collapse suction hose on the inlet line.
• Use an adjustable unloader matched to the RTX duty class to maintain working pressure while safely bypassing flow to tank.
• Add a high-pressure relief valve and a glycerin-filled gauge for commissioning and diagnostics.
• Include a thermal relief on the bypass loop to protect seals during extended gun-closed operation.

Integration Checklist

• Match motor displacement and available hydraulic flow to the required pump speed under load.
• Verify upstream relief settings and confirm return filtration, reservoir volume, and cooling capacity for the duty cycle.
• Provide a case drain if the motor build specifies it and route above tank oil level.
• Select nozzle orifice for the desired flow and pressure; never overspeed the pump.
• Plan a low-pressure recirculation path for prolonged bypass operation.
• Schedule periodic torque checks on head, manifold, base, and coupling fasteners.

HYD-RTX85-DD Where It Excels

• Mobile wash skids on service trucks and trailers.
• Municipal fleet and sanitation vehicles.
• Equipment-yard rinse stations and rental turn-backs.
• Food & beverage sanitation and packaging rooms (observe local hygienic standards).
• Marine and dock washdown on tug and work boats.

Ownership, Warranty & Support

• AR pumps HYD-RTX85-DD ship with oil in the crankcase and include a vented dipstick and sight glass for proper fill and breathing under thermal expansion.
• Follow Annovi Reverberi’s lubricant recommendations and service intervals, maintain inlet screening, and keep the shaft/seal area clean during service.
• Pump is covered by a 5-year limited, conditional warranty from Annovi Reverberi.
• Proper installation (hydraulic and water), filtration, lubrication, and operation within published limits are required for coverage.
• Normal wear items such as seals and valves are treated as consumables.
