HYD-RTX50-DD Hydraulic Motor Pump | 13 GPM 4350 PSI

HYD-RTX50-DD Hydraulic Motor Pump | 13 GPM 4350 PSI

• HYD-RTX50-DD is a compact, belt-free hydraulic drive package that directly couples a
  low-speed/high-torque (LSHT) hydraulic motor to an Annovi Reverberi RTX50 high-pressure
  triplex plunger pump on a rigid, alignment-stable base.
• Delivers serious cleaning power in tight spaces while keeping shaft centerlines true, protecting bearings
  and seal packs and reducing vibration.
• RTX50 water end is sized for approximately 13 GPM (≈50 L/min) at 4350 PSI (≈300 bar) near 1450 RPM,
  giving strong impact with smooth, controllable torque for single- or dual-gun washdown and process rinse duty.
• Manufactured in Modena, Italy by Annovi Reverberi, an industry leader in high-pressure
  pump quality since 1958.
• Assembly ships service-ready with factory oil fill, vented dipstick, and clear sight glass so a single
  technician can perform pre-start checks and routine PM quickly.

Hydraulic Motor & Circuit

• Uses a displacement-matched LSHT gerotor/geroler-type hydraulic motor (brand may vary)
  sized to reach the target RTX50 RPM and torque at pressure.
• Integrates into mobile or plant hydraulic circuits via pressure and return ports typically specified
  at SAE-12 (3/4″ ORB), with an auxiliary case-drain port commonly
  SAE-8 (1/2″ ORB) when required by the motor.
• Observe A/B port orientation for correct rotation and route the case drain above reservoir oil level
  to prevent aeration.
• Size hoses generously, respect bend radii, and avoid tight clamps or restrictions that create heat and
  pressure drop.
• Protect the circuit with upstream reliefs suitable for 300-bar service and provide
  10–25 μm return filtration with an adequate β-rating.
• Size the reservoir for heat rejection using a practical rule of 2–3× total system flow
  and add an oil cooler for hot climates, prolonged bypass, or continuous duty.

HYD-RTX50-DD Pump Ports & Water-Side Plumbing

• RTX50 manifolds are typically 1″ F BSPP on the inlet and
  1/2″ F BSPP on the discharge; adapters to NPT are readily available.
• Keep the suction run short, straight, and oversize from a flooded supply to protect inlet vacuum and
  volumetric efficiency.
• Add a coarse inlet strainer and use anti-collapse suction hose to help prevent cavitation and premature wear.
• Use an adjustable unloader matched to HYD-RTX50-DD RTX duty class to maintain working pressure while safely bypassing
  flow to tank.
• Include a high-pressure relief 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 or bypass operation.

HYD-RTX50-DD Integration Checklist

• Match motor displacement and available hydraulic flow to achieve ≈1450 RPM at the required working pressure.
• Verify upstream hydraulic relief settings are appropriate for 300-bar (4350 PSI) service.
• Include a case drain if specified by the selected motor and route it above tank oil level.
• Select nozzle orifices to achieve the desired 13 GPM @ 4350 PSI duty point and never overspeed
  the pump.
• Plan a low-pressure recirculation/bypass path to tank for prolonged trigger-off periods.
• Confirm seal and O-ring compatibility when detergents or process fluids are used and observe published
  temperature limits.
• Document final relief, unloader, and nozzle settings on the equipment decal for future diagnostics.

HYD-RTX50-DD Why Direct Drive

• Smooth torque transfer for stable pressure, calmer trigger cycling, and reduced hose whip.
• Cleaner than belt systems: no belt dust, no tensioning, fewer guarded rotating parts, and less bulk.
• Alignment-stable geometry reduces side-load on bearings, extending seal and bearing life.
• Compact footprint with predictable hose routing supports repeatable OEM builds and easy retrofits.
• Open service access makes single-tech preventive maintenance fast and repeatable.

Typical Applications HYD-RTX50-DD

• Tug-boat and dock washdown in marine and port environments.
• Aquaculture pens and marina sanitation systems.
• Food & beverage sanitation lines and packaging rooms
  (always observe local hygienic standards and materials compatibility).
• Agriculture and ranch equipment wash bays and barn cleanup stations.
• Heavy-equipment yards and rental return lines for construction and industrial fleets.
• Municipal fleet and sanitation vehicles, street and infrastructure cleaning rigs.
• Conveyor and parts-cleaning cells and plant maintenance carts.
• Contractor rigs that already carry hydraulic power on trucks, trailers, or skids.

Ownership & Key Details at a Glance

• Pump manufactured by Annovi Reverberi, Modena, Italy and covered by a
  5-year limited, conditional warranty when installed and operated within published limits.
• Warranty requires proper hydraulic and water installation, adequate filtration, correct lubrication,
  and operation within rated pressure, speed, and temperature.
• Normal wear items such as seals and valves are treated as consumables; seal kits and valve kits are widely
  available.
• Every AR pump ships with oil in the crankcase and includes a vented dipstick and sight glass for proper fill
  and breathing under thermal expansion.
• Performance target: ≈13 GPM (≈50 L/min) @ ≈4350 PSI (≈300 bar) near 1450 RPM in a compact,
  belt-free hydraulic package.
• Benefits summary: compact geometry, smooth torque, reduced vibration, predictable service access, and
  proven RTX50 durability for demanding washdown and process-cleaning work.
