HYD-RTD-HW80.300HN-DD Hydraulic Pump | Hot Water 21 GPM 4350 PSI

HYD-RTD-HW80.300HN-DD Hydraulic Pump | Hot Water 21 GPM 4350 PSI

• HYD-RTD-HW80.300HN-DD is a ready-to-integrate hydraulic drive package that directly couples a
  low-speed, high-torque hydraulic motor to an Annovi Reverberi RTD HW80.300HN triplex plunger pump
  on a rigid, alignment-stable base.
• Delivers approximately 21 GPM (80 L/min) at 4350 PSI (300 bar) at 1000 RPM with no belts, pulleys,
  or daily retensioning.
• Built in Modena, Italy by Annovi Reverberi—the global leader in high-pressure pump quality since
  1958.
• HW/HN configuration: PTFE (polytetrafluoroethylene) high-temperature seal pack and nickel-plated
  brass head for elevated durability in hot, wet, or chemically aggressive environments where standard brass may not
  be sufficient.
• Direct-drive (DD) coaxial coupling keeps shaft centerlines true, reducing side loading on bearings and seal packs so
  the pump runs smoother, vibrates less, and enjoys longer service life.
• Compact footprint and service-friendly layout: clear access to coupling hardware, oil sight glass, and vented
  dipstick; base geometry anticipates real plumbing with short, direct suction and tidy pressure/bypass routing.

Hydraulic Interface & Circuit Design

• Uses a common LSHT hydraulic motor (gerotor/geroler style; manufacturer may vary) sized to achieve
  rated pump speed and torque at pressure.
• Typical hydraulic ports: SAE-12 (3/4″ ORB) pressure/return plus an auxiliary
  SAE-8 (1/2″ ORB) case-drain—verify exact porting on the selected motor build.
• Observe correct A/B port orientation for rotation; route the case drain above reservoir oil level to prevent
  aeration and foaming.
• Size hoses for expected flow with generous IDs and bend radii that avoid restriction, heat, and pressure loss.
• Protect the circuit with upstream relief valves suitable for 300 bar service and specify
  10–25 μm return filtration with an adequate β-rating to safeguard motor and valve life.
• Size the hydraulic reservoir for heat rejection (rule of thumb: 2–3× total system flow) and add an
  oil cooler for hot climates, prolonged bypass, or continuous-duty applications.

Water-Side Plumbing & Hot-Water Capability

• RTD series porting: HYD-RTD-HW80.300HN-DD typical configuration is a 1-1/2″ female inlet and
  1″ female discharge (BSP-F); adapters to NPT are readily available.
• Keep the suction run short, straight, and oversize; add a coarse inlet strainer and use anti-collapse suction hose
  to preserve volumetric efficiency and prevent cavitation.
• Install a correctly sized unloader valve to maintain working pressure while safely bypassing flow
  to tank; add a high-pressure relief valve and a glycerin-filled gauge for
  commissioning and diagnostics.
• As a “HW” hot-water-rated pump, it is suited for elevated water temperatures within Annovi
  Reverberi’s published limits—verify seal and O-ring compatibility where detergents or process fluids are used.

HYD-RTD-HW80.300HN-DD Integration Checklist

• Size motor displacement to reach 1000 RPM under load at the target working pressure.
• Confirm the prime mover and valve stack can supply the required hydraulic flow with margin for other actuators on
  the circuit.
• Set hydraulic reliefs accurately; verify reservoir capacity, filtration, and cooling are appropriate for the duty
  cycle.
• Include a thermal relief valve on the water bypass loop to protect seals during extended
  gun-closed or recirculation operation.
• Verify nozzle sizing at the chosen working pressure/flow; never overspeed the pump or exceed published limits.
• Schedule periodic torque checks on pump head, manifold, base, and coupling fasteners as part of preventive
  maintenance.

Typical Applications

• Tug-boat and dock washdown; marina and aquaculture sanitation.
• Food & beverage sanitation and packaging lines (observe local hygienic and regulatory standards).
• Municipal fleet and sanitation trucks; vacuum and jetter support skids.
• Agriculture and ranch equipment wash, fertilizer and barn cleanup.
• Heavy-equipment yards and rental fleets; conveyor and plant maintenance cells in industrial facilities.
• Contractor and mobile wash rigs that already carry hydraulic power.
