HYD-RTX70WC Hydraulic Motor Pump | RTX70WC Series

HYD-RTX70WC Hydraulic Motor Pump

• HYD-RTX70WC is a compact, belt-free hydraulic drive package that directly couples a
  low-speed/high-torque (LSHT) hydraulic motor to an Annovi Reverberi RTX70WC triplex plunger
  pump on a rigid, alignment-stable base.
• Delivers big-machine cleaning power in a footprint that fits trailers, service bodies, vans, and plant carts.
• Selected for approximately 70 L/min (≈18.5 GPM) at up to 300 bar (≈4350 PSI) when operated
  near 1450 RPM.
• Provides smooth torque, steady pressure, and dependable performance for industrial washdown and process
  rinse duty.
• Shared motor/pump mounting plane keeps shaft centerlines true, reducing side load on bearings and seal packs
  and helping the assembly run cooler and longer than belt-drive systems.
• Ships service-ready with clear access to the coupling, fasteners, oil sight glass, and a vented dipstick so a
  single technician can handle checks, oil changes, and torque verification with common tools.

Hydraulic Motor & Circuit

• Uses a displacement-matched LSHT gerotor/geroler-type hydraulic motor (manufacturer may
  vary) sized to reach target HYD-RTX70WC 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 selected 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 restriction, pressure loss, and heat build-up.
• Protect the circuit with upstream relief valves suitable for 300-bar service.
• Specify return filtration in the 10–25 μm range with an adequate β-rating to protect the
  motor and valve stack.
• Size the reservoir for heat rejection (practical rule: 2–3× total system flow) and add an
  oil cooler for hot climates, prolonged bypass, or continuous-duty operation.

HYD-RTX70WC Pump Ports & Water-Side Plumbing

• HYD-RTX70WC Hydraulic Motor Pump  manifolds are easy to connect, 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 protect inlet vacuum and volumetric efficiency.
• Include a coarse inlet strainer and use anti-collapse suction hose to prevent cavitation.
• Use a correctly sized unloader matched to RTX duty class to maintain working pressure while
  safely bypassing flow.
• Add a high-pressure relief valve and a glycerin-filled pressure gauge for
  commissioning and ongoing diagnostics.
• Include a thermal relief valve on the bypass loop to protect seals during extended
  gun-closed or bypass operation.

Integration Checklist

• Confirm the prime mover and valve stack can supply the hydraulic flow and pressure required to spin the pump
  to target RPM with margin for other actuators.
• Match motor displacement and available hydraulic flow to the desired pump speed at your chosen working
  pressure—never overspeed the pump.
• Verify upstream relief settings, return filtration spec, reservoir volume, and cooling capacity against the
  expected duty cycle.
• Include a case drain if specified by the motor manufacturer and route it above reservoir oil level.
• Select nozzle orifices for the required flow/pressure point (≈18.5 GPM up to 300 bar).
• If detergents or process fluids are used, confirm seal and O-ring compatibility and observe published
  temperature limits.

HYD-RTX70WC Typical Applications

• Mobile wash skids on service trucks and trailers.
• Municipal fleet and sanitation vehicles and public-works rigs.
• Equipment-yard rinse stations and rental-fleet wash bays.
• Conveyor and parts-cleaning cells and general plant maintenance carts.
• Food & beverage sanitation and packaging lines (follow 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 need compact, high-duty output.

• Manufacturer & origin: Annovi Reverberi, Modena, Italy—leader in high-pressure pump
  quality since 1958.
• Water performance: ≈70 L/min (≈18.5 GPM) @ up to 300 bar (≈4350 PSI) near 1450 RPM.
• Hydraulic motor: LSHT style, displacement-matched; hydraulic ports typically SAE-12
  pressure/return with SAE-8 case drain (verify on selected motor).
• Pump ports: typically 1-1/4″ F-BSPP inlet and 1/2″ F-BSPP outlet; adapt to NPT as
  required.
• Service & reliability features: alignment-stable base, compact footprint, no belts to
  tension, predictable hose routing, and quick single-tech preventive maintenance.
• Ships with: factory oil fill, easy-view sight glass, and vented dipstick for proper fill and
  breathing under thermal expansion.
• Warranty: 5-year limited, conditional coverage from Annovi Reverberi—proper installation
  (hydraulic and water), filtration, lubrication, and operation within published limits are required; seals
  and valves are considered consumable wear items.
