HYDBK2 | Hydraulic Motor Pump Base Kit 2 with Mounting Hardware

HYDBK2 Adjustable Hydraulic Pump & Motor Mounting Kit

System Overview

• Enhanced mounting system designed to hold a hydraulic drive motor and an Annovi Reverberi triplex plunger pump on a shared rigid plane.
• Incorporates slide-adjust motor mounts for precise centerline and coupling alignment.
• Thicker base resists flex to maintain alignment stability under load.
• Reduces bearing and seal side-loading while lowering vibration.
• Layout supports short suction runs and clean pressure and bypass routing.
• Preserves access to oil sight glass, vented dipstick, and fasteners for single-technician service.

Hydraulic Motor Compatibility

Motor Fitment & Ports

• Accepts common LSHT hydraulic motors.
• Compatible with external-gear, gerotor, and geroler motor designs.
• Common motor brands include Marzocchi, Parker, and Danfoss.
• Typical pressure and return ports are SAE-12 ORB (3/4″).
• Auxiliary SAE-8 ORB (1/2″) case drain used when required by motor design.
• Slide mounts provide adjustment travel to set coupling depth and restore alignment after service.

HYDBK2 Hydraulic Porting & Routing

Connection Guidelines

• Observe A/B port orientation to ensure correct motor rotation.
• Route case drain above reservoir oil level to prevent aeration.
• Size hose IDs generously and maintain proper bend radii.
• Avoid restrictions near unloader and relief components.

Pump Manufacturer & Origin

AR Pump Standards

• Water end is always Annovi Reverberi.
• Pumps engineered and built in Modena, Italy.
• Ships with factory crankcase oil.
• Includes vented dipstick and easy-view sight glass.

Pump Porting & Warranty

Manifold Sizes & Coverage

• Small-frame RK and RK21xx pumps use 1/2″ F-BSPP inlet and 3/8″ F-BSPP outlet.
• Mid-frame XWL and RTX pumps use 1″ F-BSPP inlet and 1/2″ F-BSPP outlet.
• Adapters to NPT readily available.
• AR pumps covered by a 5-year limited, conditional warranty.
• Coverage requires proper installation, filtration, lubrication, and operation.
• Seals and valves are treated as normal wear items.

HYDBK2 Included Components

Kit Contents

• Heavy base plate.
• Adjustable motor slide set.
• Pump and motor mounting hardware.
• Shim pack for parallel and height correction.
• Coupling-guard standoffs and fasteners.
• Bench-ready kit for repeatable OEM and fleet builds.

Installation Notes

Alignment Procedure

• Set motor and pump on a shared centerline.
• Verify face runout and coupling engagement depth and gap.
• Snug slides, test-run, recheck alignment, then final-torque fasteners.
• Re-torque base and coupling hardware after initial run-up.

Integration Checklist

Engineering Verification

• Define required nozzle result and work backward to flow, pressure, and pump speed.
• Match motor displacement and hydraulic supply to target pump speed.
• RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³).
• Torque ≈ displacement (in³) × PSI ÷ 6.283.
• Hydraulic horsepower ≈ GPM × PSI ÷ 1714 with efficiency applied.
• Set upstream reliefs for duty pressure.
• Specify 10–25 micron return filtration with appropriate beta rating.
• Size reservoir at 2–3× total system flow.
• Add oil cooling for hot climates, prolonged bypass, or continuous duty.
• Include case drain when required and keep return plumbing unrestricted.
• Install adjustable unloader, high-pressure relief, glycerin-filled gauge, and thermal relief valve.
• Never overspeed the pump or run it dry.

HYDBK2 Typical Applications

Use Environments

• Mobile wash skids and service trucks.
• Enclosed van systems and plant carts.
• Municipal, DOT, rental, industrial, and contractor platforms.
• Food and beverage sanitation lines observing local standards.
• Marine and tug-boat washdown.
• Agriculture, ranch, equipment-yard, and plant maintenance systems.

Why Choose HYDBK2
