HYD-RTX50 Hydraulic Motor Pump | RTX50 Series

HYD-RTX50 Hydraulic Motor Pump | RTX50 Series

• HYD-RTX50 is a compact hydraulic motor-driven pump assembly built around the proven
  Annovi Reverberi RTX50 triplex platform for crews that want reliable daily performance
  without the complexity of belt drives.
• A displacement-matched hydraulic motor is coupled directly to the RTX50, shrinking the footprint, lowering
  vibration, and keeping motor and pump on the same centerline so bearings and seal packs live longer.
• The rigid shared base preserves alignment through transport and hard use, while the layout leaves clear access
  to the coupling, oil sight glass, dipstick, and fasteners so one technician can complete preventive maintenance
  quickly with common tools.
• The RTX family is designed for high-pressure duty with a rigid crankcase, forged connecting rods, oversized
  bearings, and quality sealing elements that turn clean inlet conditions into smooth, repeatable output.
• Paired with hydraulic drive, HYD-RTX50 delivers a quiet, controllable package that installs neatly on mobile
  wash skids, vans, and plant carts where space and service access are at a premium.

Why Hydraulic Direct Drive

• Leverages the host machine’s existing hydraulic power instead of separate engines or electric motors.
• Eliminates belts, belt dust, re-tensioning, and large belt guards that add bulk and maintenance.
• Provides smooth torque delivery that calms hose whip and pressure oscillation for better operator comfort
  and component life.
• Keeps geometry compact so tanks, filters, hose reels, and guides can be plumbed tidily around the pump
  assembly.
• Alignment-stable form factor with predictable mounting lands and slot-friendly patterns supports repeatable
  OEM builds.

What’s Included

• RTX50 triplex plunger pump and a compact hydraulic motor mounted on a shared rigid base.
• Matched coupling, guard standoffs, and installation hardware.
• Concise startup checklist and torque guidance to standardize first installs and future fleet deployments.

What the Installer Provides

• Hydraulic power source and hoses sized for required flow, pressure, cooling capacity, and filtration quality.
• Correctly sized unloader and secondary relief valve appropriate to the working pressure.
• Inlet strainer, supply hose, discharge hose, gun, wand, and nozzle set sized for the desired duty point.
• Optional accessories: hose reel, surface cleaner, chemical injection hardware, and additional valving as
  required.
• Short, low-restriction bypass return routed back to tank or suitable drain below fluid level to limit aeration.

Integration Checklist

• Size motor displacement to reach target pump RPM at available hydraulic flow:
  rpm ≈ 231 × hydraulic gpm ÷ motor displacement (in³).
• Confirm motor rotation and coupling engagement before opening the water supply or applying system pressure.
• Set upstream hydraulic reliefs correctly and document final operating pressure on the equipment decal.
• Keep suction plumbing generously sized, airtight, and as straight/short as possible; maintain a flooded inlet
  whenever practical.
• Include a case drain if the motor requires it and route above reservoir oil level to prevent aeration.
• Respect hose bend radii and clamp placement to avoid restriction, heat generation, and premature hose fatigue.
• Mount on a flat structure, torque hardware in a cross pattern, and recheck fasteners after the first hour of
  run time.
• HYD-RTX50 Plan bypass routing back to tank below fluid level to reduce foaming and speed de-aeration.

HYD-RTX50 Maintenance Routine

• Change pump oil on the manufacturer’s schedule and use approved lubricants.
• Keep hydraulic oil clean, properly filtered, and within recommended temperature limits at all times.
• Inspect coupling wear surfaces, guard clearance, and base fasteners at regular intervals; re-torque after
  initial run-in.
• Replace inlet screens and any high-pressure filters on a defined preventive-maintenance calendar.
• If performance fades, verify nozzle size, unloader setting, and suction supply conditions before opening
  the pump.
• Rinse chemical lines at day’s end, never run the pump dry, and winterize with pump-safe antifreeze for
  cold storage.
• Record service dates and pressure settings to standardize fleet practices and speed diagnostics.

Operator Tips

• Choose nozzle orifice to hold working pressure under flow at the desired GPM, matching the system duty point.
• Use approved detergents at proper dilution and flush with clean water to protect valves and seals.
• Keep suction airtight, as short as practical, and free of sharp rises that can trap air.
• Bring pressure up gradually after purging air from the system and confirm unloader function before regular use.
• Monitor bypass line temperature during extended trigger-off periods and adjust operating practices or cooling
  if heat builds.

HYD-RTX50 Typical Applications

• Fleet and equipment wash at depots, rental return lines, agricultural yards, and construction sites.
• Facilities maintenance for docks, shop floors, waste areas, exterior hardscape, and loading zones.
• Municipal and campus cleaning for parks, transit shelters, benches, sidewalks, and building entries.
• Contractor and OEM rigs that need compact, reliable output with consistent alignment across vehicles
  and platforms.

Planning Formulas & Quick Checks

• Estimated torque in lb-in:
  Torque ≈ motor displacement (in³) × hydraulic psi ÷ 6.283.
• Hydraulic horsepower:
  HP ≈ hydraulic gpm × psi ÷ 1714, then apply efficiency to estimate shaft power.
• Verify inlet vacuum stays within pump limits—long or restrictive suction lines are common performance killers.
• Document final relief and unloader settings after commissioning for faster future troubleshooting.
