HYD-RTX85WC Hydraulic Motor Pump | RTX85WC

HYD-RTX85WC Hydraulic Motor Pump | RTX85WC Series

• HYD-RTX85WC is a compact, belt-free hydraulic drive package that directly couples a
  low-speed/high-torque (LSHT) hydraulic motor to an
  Annovi Reverberi HYD-RTX85WC high-pressure triplex plunger pump on a shared, rigid mounting plane.
• Delivers big-equipment cleaning power in a footprint that fits trailers, service bodies, vans, and plant carts.
• Manufactured in Modena, Italy by Annovi Reverberi—industry leader in high-pressure pump
  quality since 1958.
• Performance target of approximately 85 L/min (≈22.5 GPM) at up to
  300 bar (≈4350 PSI) when operated near 1450 RPM; select nozzle orifices for
  your chosen working point and never overspeed the pump.
• Shared mounting plane keeps shaft centerlines true, minimizing side loading on bearings and seal packs so the
  pump runs smoother, vibrates less, and lasts longer than belt systems that drift with heat and tension.
• HYD-RTX85WC Installer-friendly layout with clear access to coupling, easy-view oil sight glass, vented dipstick, and
  fasteners so one technician can handle coupling checks, oil changes, and periodic torque verification.

Hydraulic Motor & Circuit

• Uses a displacement-matched LSHT gerotor/geroler-type hydraulic motor—manufacturer may vary—
  selected to achieve the target pump RPM and torque at pressure.
• Integrates into mobile or plant circuits via pressure and return ports typically
  SAE-12 (3/4″ ORB), with an auxiliary case-drain port commonly
  SAE-8 (1/2″ ORB) when the motor build requires it.
• 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 flow restriction, pressure drop, and unnecessary heat.
• Protect the circuit with upstream relief valves appropriate for 300-bar service.
• Specify return filtration in the 10–25 μm range with an adequate β-rating, and size the
  hydraulic reservoir for heat rejection (rule of thumb: 2–3× total system flow).
• Add an oil cooler for hot climates, prolonged bypass operation, or continuous-duty cycles.

Pump Ports & Water-Side Plumbing

• RTX85WC manifolds are straightforward to plumb with typical ports of a
  1-1/4″ female BSPP inlet and a 1/2″ female BSPP discharge;
  adapters to NPT are readily available.
• Keep the suction run short, straight, and oversize to preserve volumetric efficiency and prevent cavitation.
• Use a coarse inlet strainer and anti-collapse suction hose for reliable inlet conditions.
• Position the unloader where service access stays open for future adjustments and maintenance.
• Include a high-pressure relief valve and a glycerin-filled gauge for
  commissioning and diagnostics.
• Add a thermal relief valve on the bypass loop to protect seals during extended gun-closed
  operation.

HYD-RTX85WC Integration Checklist

• Match hydraulic motor displacement and available oil flow to the required pump speed at your chosen working
  pressure.
• Verify upstream relief settings, return filtration spec, reservoir volume, and cooling capacity for the
  expected duty cycle.
• Provide a case drain if specified by the motor build and route it above tank oil level.
• Select nozzle orifices for the desired flow/pressure and avoid over-speeding the pump.
• Plan a low-pressure recirculation path for prolonged bypass operation.
• Schedule periodic torque checks on head, manifold, base, and coupling fasteners to preserve alignment and
  reliability.

HYD-RTX85WC Typical Applications

• Mobile wash skids and work-truck bodies for industrial and contractor cleaning crews.
• Municipal fleet and sanitation vehicles, public-works and utility rigs.
• Equipment-yard rinse stations and rental fleets needing high-duty washdown.
• Conveyor and parts-cleaning cells and general plant maintenance carts.
• Food & beverage sanitation lines and packaging rooms (observe local hygienic standards).
• Marine and dock washdown on tug/work boats and aquaculture facilities.
• Agriculture and ranch equipment wash and barn/facility cleanup.
• Contractor rigs that already carry hydraulic power and require big-equipment cleaning capability.
