HYD-XJS1114 Hydraulic Motor Pump | XJS1114 Series

HYD-XJS1114 Hydraulic Motor Pump | XJS1114 Series

• HYD-XJS1114 is a compact, belt-free hydraulic drive package that couples a
  low-speed/high-torque (LSHT) hydraulic motor directly to an
  Annovi Reverberi XJS1114 three-piston pump HYD-XJS1114 on a rigid, alignment-stable base.
• Delivers approximately 2.9 GPM (11 L/min) at about 2000 PSI (140 bar), providing strong
  brush and rinse feed plus stable single-gun washdown in a very small footprint.
• Ideal for trailers, service bodies, vans, and plant-floor carts where space is tight and reliability is critical.
• Built by Annovi Reverberi in Modena, Italy—leader in pump quality since 1958—with
  oil pre-filled in the crankcase, an easy-view sight glass, and a vented dipstick for fast pre-start checks.
• Common centerline between motor and pump minimizes side-loading on bearings and seal packs, lowering
  vibration and extending seal life compared with belt-driven systems.

Hydraulic Motor & Circuit

• Uses an LSHT gerotor/geroler-type hydraulic motor (brand varies by build) sized to
  deliver the torque and RPM required at working pressure.
• Typical hydraulic connections are SAE-12 ORB (3/4″) for pressure and return and
  SAE-8 ORB (1/2″) for the case drain when required by the motor build.
• Follow the motor data sheet for exact porting and observe A/B orientation for correct rotation.
• Route the case drain to tank above reservoir oil level to prevent aeration; size hoses generously and respect
  bend radii to avoid restriction and heat.
• Protect the circuit with upstream relief valves set appropriately for the XJS1114 working pressure.
• Specify 10–25 μm return filtration with an adequate β-rating and size the reservoir for
  heat rejection (practical rule: 2–3× total system flow); add an oil cooler for hot climates,
  prolonged bypass, or continuous-duty operation.
• Speed estimate for sizing:
  • RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³).

HYD-XJS1114 Pump Ports & Water-Side Plumbing

• In this flow class, AR manifolds are commonly
  1/2″ F BSPP inlet and 3/8″ F BSPP discharge;
  adapters to NPT are readily available.
• Keep the suction run short, straight, and oversized from a flooded source to protect volumetric efficiency and prevent cavitation.
• Include a coarse inlet strainer and use anti-collapse suction hose for reliable, air-free supply.
• Use an adjustable unloader matched to the XJS duty class to hold working pressure while safely bypassing flow to tank.
• Add a high-pressure relief valve and glycerin-filled gauge for commissioning and diagnostics.
• Install a thermal relief valve on the bypass loop to protect seals during extended gun-closed or low-flow operation.

Integration & Best Practices

• Size motor displacement and available hydraulic flow to achieve the target pump RPM at your chosen pressure,
  using the RPM formula above.
• Verify upstream relief settings, return filtration, reservoir volume, and cooling capacity for the duty cycle.
• Include a case drain whenever specified by the motor manufacturer and route it above tank oil level.
• Confirm seal and O-ring compatibility if detergents, saltwater, or other process fluids are used.
• Never overspeed the pump or run it dry; always operate within the published flow, pressure,
  and temperature limits.
• Plan a low-pressure recirculation path for prolonged bypass to prevent heat build-up in the pump head.
• Schedule periodic torque checks on head, manifold, base, and coupling fasteners—especially after initial run-in.

HYD-XJS1114 Why Direct Hydraulic Drive

• Smooth LSHT torque delivers stable pressure and calm trigger cycling.
• No belts to tension, no belt dust, and reduced guard bulk for cleaner layouts.
• Rigid alignment reduces bearing side-load and extends seal and bearing life.
• Predictable hose routing supports repeatable OEM builds and tidy skids.
• Compact footprint makes it easy to package HYD-XJS1114 in small trailers, vans, and enclosures.
