HYD-RTXGZ Hydraulic Motor Pump | RTXGZ Series

HYD-RTXGZ Hydraulic Motor Pump | RTXGZ Series

• HYD-RTXGZ is a ready-to-integrate hydraulic drive package that couples a
  low-speed/high-torque hydraulic motor directly to the
  Annovi Reverberi RTXGZ high-pressure triplex plunger pump on a shared, rigid mounting plane.
• Built in Modena, Italy by Annovi Reverberi—industry leader in pump quality since 1958.
• Direct-coupled geometry eliminates belts and bulky guards, shrinking the footprint and keeping shaft
  centerlines true to minimize side loading on bearings and seal packs.
• Alignment-stable package helps the pump run smoother, vibrate less, and last longer in
  continuous-duty fleets.
• Assembly arrives service-friendly and installer-ready with clear access to the coupling, easy-view oil
  sight glass, and vented dipstick so one technician can perform routine checks and oil changes quickly.

Hydraulic Motor & Circuit

• Uses a displacement-matched LSHT (gerotor/geroler-type) hydraulic motor—brand may vary—
  selected to achieve the target pump RPM and torque at pressure.
• Integrates cleanly into standard mobile or industrial 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 bend radii to avoid restriction and unnecessary heat generation.
• Protect the circuit with upstream reliefs appropriate to RTX service (up to
  300 bar / 4350 PSI).
• Specify return filtration in the 10–25 μm range with an adequate β-rating and size the
  reservoir for heat rejection; add an oil cooler for hot climates, long bypass periods, or continuous
  operation.

Pump Ports & Water-Side Plumbing

• RTX HYD-RTXGZ manifolds are straightforward to plumb with typical ports of a
  1″ female BSPP inlet and a 1/2″ female BSPP discharge;
  adapters to NPT are readily available.
• Keep the suction run short, straight, and oversize with a coarse inlet strainer and anti-collapse
  suction hose to preserve volumetric efficiency and prevent cavitation.
• Use a correctly sized unloader 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.
• Include a thermal relief valve on the bypass loop to protect seals during extended
  gun-closed operation.
• Base geometry anticipates real plumbing with short, direct suction, tidy pressure and bypass routing,
  and perimeter room for an unloader block without tight bends so hose runs are predictable for
  repeatable OEM builds.

Integration Checklist HYD-RTXGZ

• Match hydraulic motor displacement and available flow to the required pump RPM at the intended working
  pressure.
• Verify upstream relief settings, return filtration spec, reservoir volume, and cooling capacity for the
  duty cycle.
• Provide a case drain if specified by the motor build and route it above tank oil level.
• Select nozzle orifices for the desired working point within the RTX series limits
  (up to 300 bar / 4350 PSI; flow depends on the specific RTXGZ model) and never
  overspeed the pump.
• Plan a low-pressure recirculation path for prolonged bypass and document final relief/unloader settings
  for future service.
• Schedule periodic torque checks on HYD-RTXGZ head, manifold, base, and coupling fasteners to maintain alignment
  and reliability.

Typical Applications HYD-RTXGZ

• Mobile wash skids on service trucks and trailers.
• Municipal fleet and sanitation vehicles and public-works rigs.
• Plant carts for conveyor and parts-cleaning cells and general maintenance.
• Marine and dock washdown on tug and work boats.
• Aquaculture, agriculture, and ranch equipment wash operations.
• Food & beverage sanitation support (observe local hygienic standards).
• Rental fleets and contractor systems that already carry hydraulic power.
