HYD-RTX70 Hydraulic Motor Pump | RTX70 Series

HYD-RTX70 Hydraulic Motor Pump | RTX70 Series

• HYD-RTX70 is a compact hydraulic motor–driven pump assembly built around the proven Annovi Reverberi RTX70 triplex platform.
• Engineered for crews who want dependable daily performance without the complexity of belts and pulleys.
• Displacement-matched hydraulic motor is coupled directly to the HYD-RTX70 to reduce footprint and vibration.
• Shared shaft centerline protects bearings and seal packs, extending pump life compared to belt drives.
• Rigid shared base preserves alignment through transport and routine use.
• Perimeter layout leaves clear access to the coupling, oil sight glass, dipstick, and fasteners so a single technician can complete PM with common tools.
• Plumbing layout anticipates mobile skids and plant carts: short, direct suction, tidy pressure and bypass routing, and a short, low-restriction return to tank.

Why HYD-RTX70 Hydraulic Direct Drive

• Leverages the host machine’s existing hydraulic power source.
• Eliminates belt dust, retensioning, sheaves, and large guards.
• Provides smooth torque that calms hose whip and pressure oscillation.
• Keeps geometry compact for clean hose paths around tanks, filters, reels, and guides.

What’s Included HYD-RTX70

• RTX70 triplex plunger pump and compact hydraulic motor on a shared rigid base.
• Matched coupling, guard standoffs, and installation hardware.
• Concise startup checklist and torque guidance to standardize first installs and fleet repeats.

What the Installer Provides

• Hydraulic power source and hoses sized for required flow, pressure, cooling, and filtration.
• Correctly rated unloader and secondary relief valve for the target working pressure.
• Inlet strainer, supply hose, discharge hose, spray gun, wand, and nozzle set.
• Optional hose reel, surface cleaner, and chemical injection as required.
• Bypass return routed short and unrestricted back to tank or suitable drain.

Integration Checklist

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

Maintenance Routine

• Change HYD-RTX70 pump oil on schedule; keep hydraulic oil clean, filtered, and within temperature limits.
• Inspect coupling wear surfaces, guard clearance, and base fasteners regularly; re-torque after initial run-in.
• Replace inlet screens and any high-pressure filters per a defined PM calendar.
• If performance fades, verify nozzle size, unloader setting, suction supply, and hose condition before opening the pump.
• Rinse chemical lines at day’s end and never run the pump dry.
• For cold storage, winterize with pump-safe antifreeze and tag the assembly.
• Record service dates and pressure settings to standardize fleet practices.

Operator Tips

• Choose nozzle orifice to hold working pressure under flow; avoid oversizing tips.
• Use approved detergents at proper dilution and flush with clean water to protect valves and seals.
• Keep suction airtight and as short as practical to prevent cavitation.
• Stage reels and accessories so service access to the pump remains clear.
• After purging air, bring pressure up gradually and verify unloader function.
• Monitor bypass temperature during extended trigger-off periods.
• Wear appropriate eye, hand, and hearing protection.
• Never deadhead the pump; pressure test after installation and log results with date and technician initials.

Applications

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

Planning Formulas & Quick Checks

• Estimated torque (lb-in) ≈ motor displacement (in³) × hydraulic PSI ÷ 6.283.
• Hydraulic horsepower ≈ 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 relief and unloader settings after commissioning for faster future diagnostics.
• In short, HYD-RTX70 wraps RTX-series durability in a clean hydraulic package that installs neatly, runs smoothly, and stays easy to service across fleets and OEM builds.
