HYD-XWL50.09 Hydraulic Motor Pump | XWL50.09 Series

HYD-XWL50.09 Hydraulic Motor Pump | XWL50.09 Series

• HYD-XWL50.09 is a compact hydraulic motor–driven pump assembly built around the proven Annovi Reverberi XWL50.09 triplex platform.
• Engineered for crews who need dependable daily performance in a tidy, service-friendly package without the complexity of belts and pulleys.
• Direct hydraulic drive shrinks footprint and lowers vibration while keeping motor and pump on a shared centerline so bearings and seal packs live longer.
• A rigid, shared base preserves alignment through transport and routine use and leaves clear access to coupling, oil sight glass, dipstick, and fasteners for single-tech maintenance.
• XWL crankcase, forged connecting rods, oversized bearings, and quality sealing elements deliver smooth, repeatable output with clean water and calm inlet conditions.

Why Hydraulic Direct Drive

• Leverages an existing hydraulic circuit on the host machine—no separate engine or electric drive required.
• Eliminates belt dust, re-tensioning tasks, and bulky guards.
• Coaxial alignment cuts runout for calmer trigger feel and quieter operation.
• Smooth torque application reduces hose whip and pressure oscillation.
• Compact geometry improves safety and access near tanks, filters, and hose reels.

Installer-Friendly Design

• Short, direct suction path to protect inlet conditions and reduce cavitation risk.
• Perimeter room for an unloader block and glycerin-filled gauge.
• Short, low-restriction bypass routing back to tank.
• Predictable mounting land with guard standoffs and accessible fasteners for repeatable OEM builds.

What’s Included HYD-XWL50.09

• XWL50.09 triplex pump mated to a displacement-matched hydraulic motor on a shared rigid base.
• Coupling, guard standoffs, and matched mounting hardware.
• Concise startup checklist and torque guidance to standardize first installs and future repeats.

What the Installer Provides

• Hydraulic power source and hoses sized for the duty cycle with adequate filtration and cooling.
• Correctly rated unloader valve and secondary relief 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 system as needed.
• Short, unrestricted bypass return routed to tank or suitable drain.

HYD-XWL50.09 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.
• Set upstream hydraulic reliefs correctly and document final pressure on the equipment decal.
• Keep suction plumbing straight and generously sized; avoid elbows at the pump inlet and maintain a flooded suction whenever possible.
• 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 fasteners in a cross pattern, and recheck after the first hour of run time.

Maintenance Routine HYD-XWL50.09

• Change pump oil on schedule; keep hydraulic oil clean, filtered, and within temperature limits.
• Inspect coupling wear surfaces, guard clearance, and base hardware during each PM cycle.
• Replace inlet screens and any high-pressure filters on a defined calendar.
• If performance fades, verify nozzle size, unloader setting, and suction supply before opening the pump.
• Rinse chemical lines after use 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

• Match nozzle orifice to hold working pressure under flow; oversize tips reduce cleaning action and increase cycle time.
• 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 protect seal life and reduce noise.
• Stage reels and accessories so service access remains clear; avoid cantilever mounting that can induce vibration.
• Bring pressure up gradually after purging air and confirm unloader function.
• Monitor bypass temperature during extended trigger-off periods.

Applications That Benefit HYD-XWL50.09

• Fleet and equipment wash at depots, rental return lines, agricultural yards, and construction sites.
• Facilities maintenance for docks, shop floors, waste 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 (apply efficiency factor to estimate shaft power).
• Verify inlet vacuum remains within pump limits—restrictive suction lines are common performance killers.
• Document relief and unloader settings after commissioning for faster future diagnostics.

Safety Reminders

• Wear appropriate eye, hand, and hearing protection.
• Verify thread sealant compatibility with water and hydraulic fluids.
• Purge air from water lines before loading the system.
• Never deadhead the pump; always provide a safe bypass path.
• Pressure-test after installation and log results with date and technician initials.
