HYD5530-2 Hydraulic Motor Pump Kit | Triplex

HYD5530-2 Hydraulic Drive Kit

System Overview

• Purpose-built hydraulic motor drive kit coupling an LSHT (gerotor/geroler-type) motor directly to an Annovi Reverberi triplex plunger pump.
• Rigid, alignment-stable mounting eliminates belts and external drive components.
• Compact, belt-free solution for trailers, service trucks, enclosed vans, and plant-floor carts.
• Coaxial motor and pump share a common centerline to reduce bearing and seal side-loads.
• Eliminates belt dust, retensioning, and bulky guard requirements.
• Repeatable geometry supports OEM builds and fleet standardization.

Service & Maintenance Access

Technician Visibility

• Clear access to coupling, oil sight glass, vented dipstick, and mounting fasteners.
• Single-technician preventive maintenance supported.
• Slot-ready mounting patterns simplify inspection and pump replacement.
• Perimeter clearance supports clean routing of suction, pressure, and bypass lines.

Hydraulic Motor Interface

Motor Specification

• LSHT hydraulic motor with displacement matched to pump rated RPM and torque.
• Motor brand varies by build to meet duty requirements.
• Pressure and return ports typically SAE-12 ORB (3/4″).
• Auxiliary case drain commonly SAE-8 ORB (1/2″) when required.

Hydraulic Circuit Requirements

Plumbing & Protection

• Observe A/B port orientation to ensure correct motor rotation.
• Route case drain above reservoir oil level to prevent aeration.
• Use generously sized hoses and maintain proper bend radii.
• Set upstream relief valves to working pressure.
• Install 10–25 micron return filtration with appropriate beta rating.
• Size reservoir at 2–3× total system flow for heat rejection.
• Add oil cooling for hot climates, extended bypass, or continuous duty.

Hydraulic Sizing Reference

Engineering Formulas

• RPM ≈ 231 × hydraulic GPM ÷ motor displacement (cid).
• Torque (lb-in) ≈ displacement (cid) × system PSI ÷ 6.283.
• Hydraulic horsepower ≈ GPM × PSI ÷ 1714.
• Apply realistic efficiency factors to confirm available shaft power.

Water-Side Plumbing

Pump Connections

• Annovi Reverberi triplex plunger pumps engineered and built in Modena, Italy.
• Pumps ship with oil installed, vented dipstick, and sight glass.
• Compatible with multiple AR pump models; confirm exact porting by pump.
• Common inlet/outlet configurations include:
• 1/2″ F BSPP inlet with 3/8″ F BSPP discharge.
• 1″ F BSPP inlet with 1/2″ F BSPP discharge.
• Adapters to NPT available where required.

Water-Side Best Practices

Flow Management

• Keep suction lines short, straight, and oversized from a flooded supply.
• Use anti-collapse suction hose and coarse inlet strainer.
• Install adjustable unloader sized to selected AR duty class.
• Include high-pressure relief valve for system protection.
• Install glycerin-filled pressure gauge for commissioning and diagnostics.
• Add thermal relief valve on bypass loop for seal protection.

Installation Checklist

Commissioning Requirements

• Match motor displacement to pump rated speed under load.
• Verify hydraulic supply flow and pressure margin.
• Confirm relief settings, filtration, reservoir volume, and cooling capacity.
• Include case drain when specified by motor design.
• Avoid inlet restriction and pump overspeed.
• Select nozzle orifice to achieve target flow and pressure.
• Maintain clean hydraulic oil and follow AR lubricant intervals.
• Verify coupling engagement and fastener torque at startup.
