HYD-RCHWSS1117 Hydraulic Pump Package | 2.9 GPM 2500 PSI

HYD-RCHWSS1117 Hydraulic Pump Package | 2.9 GPM 2500 PSI

• HYD-RCHWSS1117 is a stainless-head, hot-water-duty hydraulic drive
  package that couples a low-speed/high-torque (LSHT) hydraulic motor directly to an
  Annovi Reverberi RCHWSS1117 triplex plunger pump on a rigid,
  alignment-stable base.
• Delivers compact, belt-free performance for tight skids, service bodies, enclosed
  vans, and plant carts where reliability, footprint, and easy service access matter.
• Hot-water variant selected for about 2.9 GPM (11 L/min) at up to
  2500 PSI with a 1450 RPM max operating envelope; running
  slower promotes cooler operation and long seal life.
• Stainless steel pump head resists corrosion in wet, wash-down, or chemically
  aggressive environments.
• Assembly ships pre-filled with oil and includes an easy-view sight glass and
  vented dipstick so one technician can complete pre-start checks and routine PM
  quickly.

Hydraulic Motor & Circuit

• Uses an LSHT gerotor/geroler-style hydraulic motor (brand may
  vary) sized to reach target pump speed and torque at pressure.
• Typical hydraulic ports:
  SAE-12 ORB (3/4″) pressure and return, plus
  SAE-8 ORB (1/2″) case drain when the selected motor
  requires it.
• Observe A/B port orientation for correct rotation; route the case drain above
  reservoir oil level to prevent aeration.
• Size hose IDs generously and respect bend radii on all lines to avoid restriction
  and excess heat.
• Protect the circuit with upstream reliefs appropriate for 2500 PSI duty and
  specify 10–25 μm return filtration with an adequate β-rating.
• Size the reservoir for heat rejection using a practical rule of
  2–3× total system flow and add an oil cooler for hot climates,
  prolonged bypass, or continuous duty.

HYD-RCHWSS1117 Water-Side Plumbing & Hot-Water Duty

• 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 suction plumbing short, straight, and oversize from a flooded source; use
  an anti-collapse suction hose and a coarse inlet strainer to protect volumetric
  efficiency and prevent cavitation.
• Hot-water rating to approximately 180 °F; verify feed
  temperature and chemical compatibility for detergents and sanitizers.
• Use an adjustable unloader matched to the RCHWSS duty class to hold working
  pressure while safely bypassing flow.
• Add a correctly sized high-pressure relief, a glycerin-filled gauge for
  commissioning and diagnostics, and a thermal relief valve on the bypass loop to
  protect seals during extended gun-closed operation.
• When chemicals are used, confirm seal and O-ring compatibility and flush with
  fresh water after chemical exposure and at end of shift.

Sizing & Performance Checks

• Estimate motor speed with
  RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³).
• Estimate torque with
  Torque (lb-in) ≈ displacement (in³) × PSI ÷ 6.283.
• Estimate hydraulic horsepower with
  HP ≈ GPM × PSI ÷ 1714, then apply realistic efficiencies to
  confirm shaft power at the nozzle set.
• Target about 2.9 GPM at up to 2500 PSI with calm, controllable
  flow for precision cleaning and rinse work.
• Never overspeed the pump—select nozzle orifices to stay within the RCHWSS1117
  published limits.

HYD-RCHWSS1117 Direct-Drive Advantages

• No belts to tension, no belt dust, and less guard bulk compared with
  belt-driven systems.
• Shared rigid base keeps motor and pump centerlines true, reducing side-loading
  on bearings and seal packs for smoother operation and longer life.
• Predictable geometry leaves perimeter space for an unloader block without tight
  bends.
• Preserves clear access to coupling, sight glass, dipstick, and fasteners for
  fast service by a single technician.

Applications

• Food and beverage wash-down and sanitation lines
  (observe local hygienic standards).
• Marine and shipyard cleaning and dock washdown.
• Wastewater and environmental services and municipal/DOT fleet maintenance.
• Building services and facility maintenance, compact contractor rigs, and utility
  plant carts.
• Conveyor and parts-cleaning cells and other locations where hydraulic power is
  already available and hot-water compatibility is valuable.
• OEM and fleet builds that benefit from alignment-stable bases, predictable hose
  routing, compact layouts, and single-tech preventive maintenance.

HYD-RCHWSS1117 Ownership & Warranty

• Pump manufacturer:
  Annovi Reverberi (AR), leader in quality since 1958 with pumps
  engineered and built in Modena, Italy.
• Water end is covered by a 5-year limited, conditional warranty;
  proper hydraulic and water-side installation, correct filtration and
  lubrication, and operation within published limits are required for coverage.
• Normal wear items such as seals and valves are considered consumables.
• Includes factory oil fill, vented dipstick, and easy-view sight glass to
  simplify start-up and ongoing maintenance.
