HYDB20 | Hydraulic Motor Pump Mounting Base Plate Heavy Duty

HYDB20 | Hydraulic Pump & Motor Base Plate | Painted Zinc-Plated Steel

HYDB20 is the harsh-environment member of Annovi Reverberi’s base plate line: a 10.9-gauge steel mounting plate finished in painted zinc plating — a duplex coating of paint over galvanic protection — and hole-punched for rubber isolation feet. Like its HYDB18 and HYDB19 siblings, it is the raw foundation of a pump-and-motor build: no pre-drilled pump pattern, no committed drive architecture, just factory-grade steel ready for the layout your components define. What sets the HYDB20 apart is the finish package, and on equipment that lives its whole life wet, finish is not cosmetic.

The duplex system works the way bridge and marine steel does: the zinc layer protects galvanically — sacrificing itself at any scratch before the steel corrodes — while the paint layer shields the zinc itself, multiplying the life of both. On a wash-system base, permanently splashed, chemically dosed, and bolted where nobody repaints it, that stacked protection is the difference between a plate that outlasts the pump above it and one that becomes the rust stain under it.

Where the HYDB20 Earns Its Finish

Every base plate in the line survives ordinary washdown duty; the HYDB20 is specified where the environment plays dirty. Marine and dock installations breathing salt air. Sanitation systems dosed daily with chlorinated chemistry. Agricultural rigs parked over fertilizer dust and manure wash. Municipal equipment brined every winter. Coastal fleets, softwash trailers, reclaimed-water systems — anywhere the deck around existing equipment already shows the environment winning, the duplex-finished plate is the foundation to build on.

Plate or Kit — the Same Honest Fork

Builders whose configuration matches a standard architecture should look first at the configured HYDBK kits — close-couple HYDBK1, flex-coupled HYDBK2, adjustable HYDBK3, heavy HYDBK4 — where the drive is solved and the holes are factory-drilled. The HYDB20, like its plate siblings, serves the builds those kits don’t: custom layouts, nonstandard motors, shop-standard patterns drilled in-house, and plate replacement under fielded assemblies whose original base lost its fight with the environment — the exact scenario this finish exists to prevent repeating. WSHPWR stocks the whole family and will route you honestly.

Build Notes

Lay out the pump-and-motor centerline before drilling — alignment is decided at the plate — and drill to the components’ actual foot dimensions rather than catalog nominals. Where the paint layer is cut for mounting holes, the zinc beneath continues protecting the exposed edge galvanically; touch up drilled edges anyway on the harshest installs. Fit the rubber feet before final installation, mount to flat structure, verify alignment after first run-up, and call WSHPWR for AR pump and HYDM motor pattern drawings so the HYDB20 gets drilled once, correctly.

HYDB20 Key Features & Applications

• Duplex painted-zinc finish — galvanic protection under a paint shield, the best corrosion package in the plate line.
• 10.9-gauge steel foundation, punched for rubber isolation feet; feet available separately.
• Undrilled pump/motor field — your pattern, your components, factory-grade blank.
• The replacement plate for bases the environment already beat once.
• Configured HYDBK kits available when a standard architecture fits — one family, honest routing.
• Ideal for marine and dock systems, sanitation and softwash rigs, agricultural and municipal fleets, coastal builds, and any wash assembly whose base must outlast the chemistry around it.
