HYDBK1 | Hydraulic Motor Pump Base Kit 1 with Mounting Hardware

HYDBK1 Hydraulic Base Kit for Motor and AR Triplex Pump Mounting

Product Configuration

• HYDBK1 is a standardized hydraulic base kit that provides a clean, square, alignment-stable platform to mount a hydraulic drive motor and an Annovi Reverberi (AR) triplex plunger pump on the same rigid plane.
• Heavy base plate and matched hardware hold the motor and pump on a shared centerline, reducing side-loads on bearings and seal packs so pumps run cooler, quieter, and more predictably.
• Drill-to-fit design lets builders match common hydraulic motor pilots and bolt circles as well as AR pump feet without committing to a single footprint.
• Perimeter space accommodates a coupling guard, hose clamps, and an unloader block while preserving access to the oil sight glass, vented dipstick, and fasteners so one technician can complete routine PM quickly.

Hydraulic Motor Guidance

• Intended for low-speed/high-torque (LSHT) hydraulic motors—external-gear, gerotor, or geroler types—sized to turn the selected AR pump at target RPM under load.
• Compatible with common brands such as Marzocchi, Parker, Danfoss, etc.; typical ports are SAE-12 ORB (3/4 in) for pressure and return with an auxiliary SAE-8 ORB (1/2 in) case drain when required.
• Observe A/B port orientation for correct rotation and route any case drain above reservoir oil level to prevent aeration.
• Size hose IDs generously and respect minimum bend radii to avoid restriction and pressure loss.

Pump Manufacturer and Ports

• Water end is always Annovi Reverberi—Italian pump maker and industry leader in quality since 1958; pumps engineered and built in Modena, Italy.
• Pumps ship with crankcase oil installed and include an easy-view sight glass plus vented dipstick for quick pre-start checks.
• Typical AR manifold sizes in this class include RK / RK21xx frames with 1/2 in F-BSPP inlet and 3/8 in F-BSPP outlet.
• Typical AR manifold sizes in this class include XWL / RTX mid-frames with 1 in F-BSPP inlet and 1/2 in F-BSPP outlet.
• Adapters to NPT are readily available; always verify exact porting for the chosen model in the AR North America catalog or at ARNorthAmerica.com.

Plumbing Best Practices

• Plan a short, straight, oversize suction run from a flooded source using anti-collapse suction hose.
• Install a coarse inlet strainer to protect volumetric efficiency and prevent cavitation.
• Mount an adjustable unloader sized for the pump’s duty class and include a correctly sized high-pressure relief valve.
• Add a glycerin-filled pressure gauge for commissioning and diagnostics.
• Include a thermal relief valve on the bypass loop for extended gun-closed operation.
• Keep pressure and bypass sweeps tidy and free of tight bend radii; the base footprint leaves room to route hoses cleanly without blocking service access.

System Integration Checklist

• Match motor displacement and available hydraulic flow/pressure to target pump speed using Pump RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³).
• Confirm available torque using Torque (lb-in) ≈ motor displacement (in³) × PSI ÷ 6.283 for loaded operation.
• Estimate hydraulic power using Hydraulic HP ≈ GPM × PSI ÷ 1714 and apply realistic efficiencies for sizing.
• Set upstream hydraulic reliefs correctly for the intended duty.
• Specify 10–25 μm return filtration with an adequate β-rating.
• Size reservoir for heat rejection using 2–3× total system flow as a practical rule; add an oil cooler for hot climates, prolonged bypass, or continuous duty.
• Confirm hose IDs and bend radii across suction, pressure, and bypass runs.
• Never overspeed the pump—verify that nozzle selection and hydraulic settings keep RPM within AR’s published limits.

Warranty and Ownership

• AR water ends are covered by a 5-year limited, conditional warranty.
• Coverage requires proper hydraulic and water-side installation, correct filtration and lubrication, and operation within published limits; seals and valves are treated as consumables.
• HYDBK1’s predictable geometry helps OEMs and fleets document alignment and hose routing consistently, supporting warranty records and repeatable builds.

• Use HYDBK1 to speed first installs, standardize fleet builds, and create a professional, service-friendly foundation for any hydraulic-motor-driven Annovi Reverberi pump package.
• Maintain clear access to oil sight glass, vented dipstick, and mounting fasteners to support fast routine PM.
• Verify alignment after initial run-in and re-torque hardware to maintain a stable shared centerline over time.
• Confirm hose routing remains free of abrasion points and does not restrict service access to the pump or motor.
