HYDBK3 | Hydraulic Motor Pump Base Kit 3 with Mounting Hardware

HYDBK3 Long-Travel Adjustable Hydraulic Pump & Motor Mount

System Overview

• Top-tier mounting system for pairing a hydraulic drive motor with an Annovi Reverberi triplex plunger pump on a shared rigid plane.
• Long-travel slide adjustment and thicker base stock support precise centerline and coupling alignment.
• Smarter hole and slot layout simplifies initial installation and future service.
• Delivers cleaner builds, reduced vibration, and repeatable OEM geometry.
• Open layout preserves access to coupling, oil sight glass, vented dipstick, and fasteners.
• Perimeter space supports unloader blocks and clean suction, pressure, and bypass routing.

Hydraulic Motor Compatibility & Ports

• Accepts LSHT hydraulic motors including external-gear, gerotor, and geroler designs.
• Compatible motor brands include Marzocchi, Parker, and Danfoss.
• Long-travel slides with engraved index marks enable repeatable motor positioning.
• Typical pressure and return ports are SAE-12 ORB (3/4 in).
• Auxiliary SAE-8 ORB (1/2 in) case drain used when specified by the motor.
• A/B port orientation must be observed for correct rotation.
• Case drain routed above reservoir oil level to prevent aeration.

Pump Manufacturer, Oil & Warranty

• Water end is always Annovi Reverberi.
• Pumps engineered and manufactured in Modena, Italy.
• Ships with crankcase oil installed.
• Includes vented dipstick and easy-view sight glass.
• Covered by a 5-year limited, conditional warranty.
• Warranty requires proper hydraulic and water-side installation and operation within published limits.
• Seals and valves are treated as consumable wear items.

Typical Pump Inlet & Outlet Sizes

• Small-frame RK and RK21xx pumps use 1/2 in F-BSPP inlet and 3/8 in F-BSPP outlet.
• Mid-frame XWL and RTX pumps use 1 in F-BSPP inlet and 1/2 in F-BSPP outlet.
• Adapters to NPT readily available.
• Suction runs should be short, straight, and oversized from a flooded source.
• Anti-collapse suction hose and coarse inlet strainer recommended.

What’s Included

• Heavy base plate.
• Long-travel motor slide set with engraved index marks.
• Pump and motor mounting hardware.
• Shim pack for fine alignment.
• Coupling-guard standoffs and fasteners.
• Pre-slotted patterns with drill-to-fit landings for common motor pilots and AR pump feet.

Installation Notes

• Set motor and pump on a shared centerline.
• Verify face runout and coupling engagement depth.
• Snug slides, test-run, recheck alignment, then final-torque fasteners.
• Plan hose sweeps to avoid kinks near unloader and relief components.
• Recheck coupling and base fasteners after initial run-up.

System Integration Checklist

• 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 adequate 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.

Why HYDBK3

• Rigid, alignment-stable base reduces bearing and seal side-loading.
• Long-travel indexed slides speed setup and repeatable service alignment.
• Slot-ready patterns and drill-to-fit flexibility support fleet standardization.
• Compact footprint enables short suction and clean bypass routing.
• Supports professional, repeatable builds backed by AR pump quality and warranty.

Applications

• Mobile wash skids and service trucks.
• Enclosed vans and plant carts.
• Municipal and DOT fleets.
• Rental, industrial, and contractor systems.
• Food and beverage sanitation systems observing local hygienic standards.
• Marine, dock, agriculture, ranch, and equipment-yard washdown.
