HYD-XWA8G35-F38 Hydraulic Motor Pump | XWA8G35 F38

HYD-XWA8G35-F38 Hydraulic Motor Pump | XWA8G35 F38

• HYD-XWA8G35-F38 pairs a compact hydraulic motor with the
  Annovi Reverberi XWA8G35 triplex pump through an F38 face mount
  to create a clean, belt-free drive for tight spaces that still demand reliable,
  controllable power.
• Direct coupling keeps the motor and pump on the same centerline, reducing vibration
  and side loading so bearings and seal packs last longer.
• A rigid base preserves alignment through transport and daily use, while the layout
  anticipates real plumbing and single-technician service with
  clear access to the oil sight, dipstick, and coupling.
• Perimeter space around the frame leaves room for an unloader block, gauge, and
  tidy hose routing on mobile rigs and plant carts.

HYD-XWA8G35-F38 Quick Spec Highlights

• Drive: direct hydraulic motor to XWA8G35 via F38 face mount.
• Form factor: low-profile, rigid base that resists flex for consistent alignment.
• Service access: open sight to critical service points and fasteners for fast PM.
• Use cases: wash skids, service bodies, trailers, vans, plant carts, and fixed wash stations.

Why Hydraulic Direct Drive

• Leverages an existing hydraulic circuit on the host machine—no belts,
  pulleys, or oversized guards required.
• Coaxial alignment cuts runout for calmer trigger feel, quieter operation,
  and less vibration.
• Smooth LSHT torque reduces hose whip, pressure oscillation, and premature wear
  on fittings and mounts.
• Compact package improves safety and access near tanks, filtration, reels, and hose guides.
• Hydraulic speed and flow control allow you to match flow and pressure to the job
  without overspeeding the pump.

HYD-XWA8G35-F38 Hydraulic Motor Pump | XWA8G35 F38

• XWA8G35 triplex plunger pump mated to a compact hydraulic motor on a shared, rigid base.
• Flexible coupling, guard standoffs, and matched mounting hardware for a tidy, professional assembly.
• Concise startup checklist and torque guidance to standardize first installs and fleet repeats.

What the Installer Provides HYD-XWA8G35-F38

• Hydraulic power source and hoses sized for required flow, pressure, cooling, and filtration.
• Correctly rated unloader valve and secondary pressure relief components
  for the chosen working pressure.
• Inlet strainer, supply hose, discharge hose, spray gun, wand, and nozzle set;
  optional hose reel and surface cleaner.
• Short, unrestricted bypass return routed to tank or a suitable drain.

Integration Checklist HYD-XWA8G35-F38

• Size motor displacement to achieve target pump RPM at available hydraulic flow
  (RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³)).
• Confirm rotation and coupling engagement before opening the water supply.
• Set upstream hydraulic reliefs correctly and document final pressures on the equipment decal.
• Keep suction plumbing short, straight, and generously sized;
  avoid elbows at the pump inlet and maintain a flooded suction whenever possible.
• Provide a case drain if the motor requires it and route it above reservoir oil level
  to prevent aeration.
• Respect hose bend radii and clamp positions to prevent restriction, heat, and hose fatigue.
• Mount on flat structure, torque fasteners in a cross pattern, and recheck hardware after
  the first hour of run time.

HYD-XWA8G35-F38 Maintenance Routine

• Change pump oil on schedule; keep hydraulic oil clean, filtered, and within temperature limits.
• Inspect coupling wear surfaces, guard clearance, and base hardware during preventive
  maintenance; re-torque as needed.
• Replace inlet screens and any high-pressure filters on a defined PM calendar.
• If performance fades, verify nozzle size, unloader setting, and suction supply
  before opening the pump.
• Rinse chemical inlets and lines after use; never run the pump dry.
• For cold weather, winterize with pump-safe antifreeze and tag the assembly
  before storage.
• Record service dates, pressure settings, and nozzle choices to standardize fleet practices.

Operator Tips for Productivity

• Match nozzle orifice to hold working pressure under flow—oversized nozzles reduce
  cleaning action and efficiency.
• Use approved detergents at proper dilution and flush with clean water to protect valves and seals.
• Keep suction airtight and as short as practical; starved inlets shorten seal life and
  increase noise.
• Stage reels, tanks, and accessories so service access to the pump, motor, and unloader
  remains clear.
• Train operators to bring pressure up gradually after purging air from the system.

Typical Applications

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

Planning Formulas & Checks

• Torque (lb-in) ≈ motor displacement (in³) × hydraulic PSI ÷ 6.283.
• Hydraulic horsepower ≈ hydraulic GPM × PSI ÷ 1714
  (then apply efficiency to estimate shaft power at the pump).
• 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 diagnostics later.

HYD-XWA8G35-F38 Safety Reminders

• Always wear appropriate eye, hand, and hearing protection around high-pressure
  wash systems.
• Never deadhead the pump; ensure bypass and relief paths are present and functional.
• Verify thread sealant compatibility with both water and hydraulic fluids.
• Purge air from water lines before loading the pump; pressure-test the system after
  installation and log results with date and technician initials.
