HYD-WHWLSS4115 Hydraulic Pump | 10.8 GPM 2200 PSI SS

HYD-WHWLSS4115 Hydraulic Pump | 10.8 GPM 2200 PSI Stainless Steel

• HYD-WHWLSS4115 is a compact, belt-free hydraulic drive package that directly couples a
  low-speed/high-torque (LSHT) hydraulic motor to an Annovi Reverberi stainless-head triplex plunger pump.
• Delivers approximately 10.8 GPM @ 2200 PSI at up to 1450 RPM, providing steady
  cleaning power with cool running and long seal life.
• Built in Modena, Italy by Annovi Reverberi—recognized since 1958 as a leader in
  high-pressure pump quality.
• Stainless steel head resists corrosion in wet, wash-down, or chemical-adjacent environments where
  standard brass can tarnish or pit.
• Motor and pump HYD-WHWLSS4115 share a rigid mounting plane, keeping shaft centerlines true, reducing side-load on
  bearings and seal packs, and cutting vibration versus belt drives.
• Service-friendly layout with clear access to the coupling, easy-view oil sight glass, and vented
  dipstick; pump ships pre-filled with oil for quick pre-start checks.

HYD-WHWLSS4115 Hydraulic Motor & Circuit

• Uses a displacement-matched LSHT gerotor/geroler-type motor (brand may vary) sized to
  reach the target pump speed and torque at 2200 PSI.
• Connects to mobile or plant circuits via pressure and return ports typically
  SAE-12 (3/4″ ORB), with an auxiliary case-drain port commonly
  SAE-8 (1/2″ ORB) when required by the motor build.
• Observe A/B port orientation for correct rotation; route the case drain above reservoir oil level to
  prevent aeration.
• Size hoses generously and respect minimum bend radii to avoid restriction and added heat.
• Protect the circuit with upstream relief valves suited to 2200 PSI duty.
• Specify 10–25 μm return filtration with an adequate β-rating and a reservoir sized for
  heat rejection (practical rule: 2–3× total system flow); add an oil cooler for hot
  climates, prolonged bypass, or continuous-duty cycles.
• Quick sizing guides:
  • Hydraulic HP ≈ GPM × PSI ÷ 1714 → 10.8 × 2200 ÷ 1714 ≈ 13.9 HP.
  • Motor speed ≈ 231 × hydraulic GPM ÷ motor displacement (in³).
  • Torque (lb-in) ≈ displacement (in³) × PSI ÷ 6.283 (apply realistic efficiencies).

Pump Ports & Water-Side Plumbing

• HYD-WHWLSS4115 Mid-frame stainless AR triplex in this flow class is typically ported
  1″ F BSPP inlet and 1/2″ F BSPP discharge
  (NPT adapters readily available).
• Keep the suction run short, straight, and oversize to preserve volumetric efficiency and prevent
  cavitation.
• Use a coarse inlet strainer and anti-collapse suction hose for reliable flooded-suction supply.
• Fit an adjustable unloader sized for 2200 PSI service to hold working pressure while
  safely bypassing flow.
• Add a high-pressure relief valve and a glycerin-filled gauge for commissioning and troubleshooting.
• Include a thermal relief valve on the bypass loop to protect seals during extended gun-closed or low-flow
  operation.

Integration & Sizing Checklist HYD-WHWLSS4115

• Match motor displacement and available hydraulic flow to achieve the target pump speed at 2200 PSI.
• Verify upstream hydraulic relief settings and confirm return filtration, reservoir volume, and cooling
  capacity for the duty cycle.
• Provide a case drain if specified by the motor manufacturer and route it to tank above the oil level.
• Select nozzle orifices for the desired 10.8 GPM @ 2200 PSI operating point and never overspeed
  the pump.
• Plan a low-pressure recirculation path for prolonged bypass to avoid hot-soak in the pump head.
• Schedule periodic torque checks on head, manifold, base, and coupling fasteners—especially after initial
  run-in and at regular PM intervals.

HYD-WHWLSS4115 Typical Applications

• Mobile wash skids and service-truck bodies for contract cleaning and equipment washdown.
• Sanitation and food & beverage rinse zones (following local hygienic standards).
• Marine and dock washdown on tug and work boats, plus general pier and harbor cleaning.
• Municipal fleet and public-works rigs for refuse, street, and infrastructure cleaning.
• Equipment-yard rinse stations and rental fleets for quick turn-back of machines and vehicles.
• Agriculture and ranch equipment wash for tractors, implements, and livestock areas.
• Conveyor and parts-cleaning cells in industrial plants.
• Contractor systems that already carry hydraulic power (vac-trucks, jetters, combo units, etc.).

Ownership, Service & Warranty

• Pump is engineered and manufactured by Annovi Reverberi, Modena, Italy, and ships with
  oil in the crankcase plus a sight glass and vented dipstick for quick pre-start checks.
• Follow AR recommendations for oil grade, service intervals, inlet filtration, and periodic torque checks
  on head, manifold, and coupling hardware.
• Confirm seal and O-ring compatibility with the intended water quality, detergents, or process fluids and
  observe temperature limits.
• Pump is backed by a 5-year limited, conditional warranty; proper hydraulic and water
  installation, filtration, lubrication, and operation within published limits are required for coverage.
• Seals and valves are considered consumables, with service parts, seal kits, valve kits, unloaders, and
  accessories readily available.
