HYD-RTX50WC Hydraulic Motor Pump

HYD-RTX50WC Hydraulic Motor Pump | RTX50WC Series

• HYD-RTX50WC is a compact, belt-free hydraulic drive package that directly couples a
  low-speed/high-torque (LSHT) hydraulic motor to an Annovi Reverberi RTX50WC high-pressure
  triplex plunger pump on a rigid, alignment-stable mounting plane.
• Delivers industrial cleaning power in a footprint that fits trailers, service bodies, vans, and plant carts
  while keeping shaft centerlines true to protect bearings and seal packs.
• RTX50WC water end is sized for approximately 50 L/min (≈13.2 GPM) at up to 300 bar (≈4350 PSI)
  when operated near 1450 RPM; choose nozzle orifices for the exact working point and never
  overspeed the pump.
• Motor and pump are coaxially mounted to eliminate belts, bulky guards, alignment drift, and belt dust,
  producing smoother torque transfer, steadier pressure, and longer seal life in continuous-duty fleets.
• Manufactured in Modena, Italy by Annovi Reverberi, a global leader in high-pressure pump
  quality since 1958.

Hydraulic Motor & Circuit

• Uses a displacement-matched LSHT gerotor/geroler-type hydraulic motor (brand may vary)
  sized to reach the required RTX50WC RPM and torque at pressure.
• Connects to standard mobile or plant circuits via pressure and return ports typically specified around
  SAE-12 (3/4″ ORB), with an auxiliary case-drain port commonly
  SAE-8 (1/2″ ORB) when required by the 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.
• Protect the circuit with upstream reliefs appropriate for 300-bar service and specify
  10–25 μm return filtration with an adequate β-rating.
• Size the hydraulic reservoir for heat rejection (practical rule of 2–3× total system flow)
  and add an oil cooler for hot climates, prolonged bypass, or continuous-duty cycles.
• Quick sizing checks:
  • RPM ≈ 231 × hydraulic GPM ÷ motor displacement (cid)
  • Torque (lb-in) ≈ displacement (cid) × PSI ÷ 6.283
  • Hydraulic HP ≈ GPM × PSI ÷ 1714 (apply realistic efficiencies)

Pump Ports & Water-Side Plumbing

• RTX manifolds are straightforward to plumb, with typical ports of a
  1″ female BSPP inlet and a 1/2″ female BSPP discharge;
  adapters to NPT are readily available.
• Keep the suction run short, straight, and oversize; use a coarse inlet strainer and
  anti-collapse suction hose to preserve volumetric efficiency and prevent cavitation.
• Use a correctly sized unloader matched to RTX duty class to maintain working pressure while safely
  bypassing flow to tank.
• Add a high-pressure relief and a glycerin-filled gauge for commissioning and diagnostics.
• Include a thermal relief valve on the bypass loop to protect seals during extended gun-closed or bypass
  operation.
• Base geometry anticipates real-world hose routing—short, direct suction, tidy pressure and bypass lines,
  and perimeter room for an unloader block without tight bends—so installs look professional and PM stays
  predictable.

Service Access & Maintenance HYD-RTX50WC

• Service access is intentionally open: clear line of sight to the coupling, fasteners, oil sight glass,
  and vented dipstick so routine checks and oil changes can be done quickly by a single technician.
• Every pump HYD-RTX50WC ships from the factory with oil in the crankcase plus an easy-view sight glass and
  vented dipstick for proper fill and breathing under thermal expansion.
• Follow Annovi Reverberi’s lubricant recommendations and service intervals; maintain inlet screening and
  schedule periodic torque checks on head, manifold, and coupling fasteners.
• Confirm seal and O-ring compatibility when using detergents or process fluids and observe published
  temperature limits.

HYD-RTX50WC Typical Applications

• Mobile wash skids on service trucks and trailers.
• Municipal fleet and sanitation vehicles requiring continuous-duty washdown.
• Equipment-yard rinse stations for construction and rental fleets.
• Conveyor and parts-cleaning cells and general plant maintenance carts.
• Food & beverage sanitation and processing cleanup
  (observe local hygienic standards and materials compatibility).
• Marine and dock washdown on tug and work boats, plus aquaculture facilities.
• Agriculture and ranch equipment wash bays and barn cleanup systems.
• Contractor rigs that already carry hydraulic power on trucks, vans, or trailers.
