HYDB20 | Hydraulic Motor Pump Mounting Base Plate Heavy Duty

HYDB20 Heavy-Duty Hydraulic Pump & Motor Base

System Overview

• Heavy, drill-to-fit mounting base designed to hold a hydraulic drive motor and an Annovi Reverberi triplex plunger pump on a shared rigid plane.
• Shared centerline alignment reduces side loading on bearings and seal packs.
• Helps pumps operate cooler, quieter, and longer than improvised brackets or slotted frames.
• Designed to standardize fleet builds, OEM runs, and service upgrades on legacy equipment.

Base Dimensions & Construction

Physical Characteristics

• Overall footprint measures 12 × 18 inches.
• Plate thickness is 1-5/8 inches for high rigidity.
• Heavy plate resists flex during installation and preventive maintenance.
• Provides perimeter real estate for coupling guards, hose clamps, and unloader blocks.

Service & Access Maintenance Visibility

• Open layout preserves access to oil sight glass, vented dipstick, and fasteners.
• Supports single-technician coupling inspection and routine service.
• Clear working space simplifies re-torque checks and oil changes.

Hydraulic Motor Compatibility

Motor Fitment

• Designed for LSHT hydraulic motors.
• Compatible with external-gear, gerotor, and geroler motor designs.
• Common motor brands include Marzocchi, Parker, and Danfoss.
• Motor displacement selected to achieve target pump RPM under load.

Hydraulic Porting

Connection Standards

• Typical pressure and return ports are SAE-12 ORB (3/4″).
• Auxiliary SAE-8 ORB (1/2″) case drain common on many motors.
• A/B port orientation must be observed for correct rotation.
• Case drain routed above reservoir oil level to prevent aeration.

Pump Manufacturer & Origin

AR Pump Standards

• Water end is always Annovi Reverberi.
• Pumps engineered and manufactured in Modena, Italy.
• Factory-filled with crankcase oil.
• Equipped with easy-view sight glass and vented dipstick.

Pump Porting Guidance

Typical AR Connections

• RK and RK21xx mid-frame pumps use 1/2″ F-BSPP inlet and 3/8″ F-BSPP outlet.
• XWL and RTX mid-frame pumps use 1″ F-BSPP inlet and 1/2″ F-BSPP outlet.
• Adapters to NPT are readily available.
• Exact porting should be verified in current AR North America documentation.

Warranty & Quality HYDB20 | Hydraulic Motor Mounting Base Plate

Coverage Details

• AR pumps carry a 5-year limited, conditional warranty.
• Coverage requires proper hydraulic and water-side installation.
• Correct filtration, lubrication, and operation within published limits required.
• Seals and valves are treated as normal wear items.

Plumbing & Layout Advantages

System Routing

• Square geometry supports short, direct suction and tidy pressure and bypass routing.
• Suction lines should be oversized from a flooded source.
• Anti-collapse suction hose and coarse inlet strainer recommended.
• Adjustable unloader matched to AR duty class required.
• High-pressure relief valve and glycerin-filled gauge recommended.
• Thermal relief valve required for extended gun-closed operation.

HYDB20 Integration Checklist

Engineering Verification

• Match motor displacement and hydraulic supply to target pump RPM.
• RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³).
• Torque ≈ displacement (in³) × PSI ÷ 6.283.
• Hydraulic HP ≈ GPM × PSI ÷ 1714 with efficiency applied.
• Set upstream reliefs for duty class.
• Specify 10–25 micron return filtration with adequate beta rating.
• Size reservoir at 2–3× total system flow.
• Add oil cooling for hot climates or continuous duty.
• Verify coupling engagement, guard clearance, test-run, then final torque.
