HYD-RTX30WC Hydraulic Motor Pump | RTX30WC Series

HYD-RTX30WC Hydraulic Drive Pump Package

The HYD-RTX30WC is a compact, belt-free hydraulic drive pressure washer pump package engineered for professional mobile, industrial, and OEM cleaning systems. This package directly couples a low-speed / high-torque (LSHT) hydraulic motor to the Annovi Reverberi RTX30WC triplex plunger pump on a rigid, coaxial mounting plane. By maintaining precise shaft alignment and eliminating intermediate drive components, the system delivers smooth torque transfer, stable operating pressure, and long-term mechanical reliability in demanding environments.

Manufactured in Modena, Italy by Annovi Reverberi—an industry leader in high-pressure pump engineering since 1958—the RTX30WC platform is designed for continuous-duty operation. The pump produces approximately 30 liters per minute (8.0 GPM) at pressures up to 300 bar (4,350 PSI) when operated near 1,450 RPM. This performance envelope makes the HYD-RTX30WC well suited for applications that demand strong cutting power, consistent flow, and predictable service intervals within a compact footprint.

The direct-drive hydraulic configuration eliminates belts, pulleys, guards, and tensioning hardware. This reduces vibration, prevents belt dust contamination, improves safety, and simplifies preventative maintenance for single-technician and fleet-maintained systems. The rigid mounting base ensures long-term alignment stability, protecting bearings, seals, and couplings over extended operating hours.

HYD-RTX30WC Smart Service-Ready Design

• Coaxial mounting maintains true shaft centerlines to reduce bearing and seal wear.
• Open access to the coupling allows fast visual inspection during routine service checks.
• Integrated oil sight glass provides instant crankcase oil level verification.
• Vented dipstick supports proper crankcase breathing and simplified oil changes.
• Rigid base construction minimizes alignment drift under vibration and thermal cycling.
• Designed to support repeatable OEM layouts and simplified plumbing configurations.

Hydraulic Motor Interface

• Low-speed / high-torque (LSHT) hydraulic motor using gerotor or geroler architecture.
• Motor displacement is matched to achieve target pump speed, flow, and pressure.
• Pressure and Return Ports: Typically SAE-12 (3/4″ ORB), verify per motor supplier.
• Case Drain: Typically SAE-8 (1/2″ ORB) when required by motor design.
• Correct A/B port orientation ensures proper pump rotation and performance.
• Case drain should be routed above reservoir oil level to prevent seal damage and aeration.
• Proper hose sizing and bend radius reduce restriction and hydraulic heat buildup.

Hydraulic Circuit Protection

• System relief valves rated for 300-bar operating class protect motor and HYD-RTX30WC pump.
• Return-line filtration in the 10–25 micron range with high beta ratings is recommended.
• Hydraulic reservoir sized at 2–3 times total system flow for thermal stability.
• Oil cooler recommended for high ambient temperatures or extended bypass operation.
• Proper filtration and cooling significantly extend motor and pump service life.

Water-Side Plumbing

• Inlet Connection: 1″ female BSPP (NPT adapters available as required).
• Discharge Connection: 1/2″ female BSPP.
• Short, straight suction plumbing using reinforced anti-collapse hose.
• Coarse inlet strainer protects pump efficiency and valve life.
• Unloader valve must be correctly sized and rated for RTX30WC output.
• High-pressure relief valve and glycerin-filled gauge recommended for diagnostics.
• Thermal relief valve recommended to protect pump during bypass conditions.

Maintenance & Service

• Pump HYD-RTX30WC ships with factory-filled crankcase oil.
• Oil sight glass and vented dipstick included as standard.
• Service intervals should follow Annovi Reverberi published guidelines.
• Oil changes, seal inspection, and inlet strainer cleaning form the core maintenance routine.
• Chemical or detergent use requires confirmation of seal compatibility.
• Proper nozzle orifice selection is critical to avoid over-speeding the pump.

Typical Applications

• Mobile wash skids and service truck installations.
• Municipal fleet maintenance and sanitation vehicles.
• Rental yards and heavy-equipment rinse stations.
• Conveyor-based parts washing and industrial cleaning cells.
• Food and beverage plant sanitation support systems.
• Marine, dock, and port washdown operations.
• Agricultural and ranch machinery cleaning.
• Contractor rigs utilizing existing hydraulic power sources.

Warranty & Ownership

• Manufactured by Annovi Reverberi in Modena, Italy.
• Covered by a 5-year limited, conditional pump warranty.
• Proper hydraulic and water-side installation required for warranty coverage.
• Seals and valves classified as normal wear components.
