HYD-RK1520A Hydraulic Motor Pump Package | RK1520A
- HYD-RK1520A is a compact hydraulic motor–driven pump assembly
built around the proven Annovi Reverberi RK1520A triplex platform. - Direct hydraulic drive replaces belts and pulleys to shrink footprint, lower
vibration, and keep motor and pump on the same centerline so bearings and seal
packs live longer. - A rigid shared base preserves alignment through transport and daily use, while
the layout leaves clear access to the coupling, oil sight, dipstick, and
perimeter fasteners for single-tech preventive maintenance. - RK-series construction—durable crankcases, oversized bearings, forged
connecting rods, and quality seals—turns clean inlet conditions into smooth,
repeatable output for equipment washdown, facility care, vehicle cleaning, and
light industrial sanitation.
Quick Specs & Form Factor
- Drive: direct hydraulic motor to RK1520A triplex pump.
- Form factor: low-profile, rigid base to preserve alignment and
simplify mounting. - Service access: open sight to oil level, dipstick, coupling,
and perimeter hardware. - Intended use: mobile wash skids, service bodies, vans, plant
carts, and fixed cleaning stations.
Why Hydraulic Direct Drive
- Leverages an existing hydraulic circuit on the host machine, eliminating belts,
pulleys, and large guards. - Coaxial alignment cuts runout for calmer trigger feel, smoother operation, and
quieter jobsites. - Smooth torque application reduces hose whip, pressure oscillation, and
premature component wear. - Compact package improves safety and working access near tanks, filtration, and
hose reels. - Speed control through hydraulics lets you match flow and pressure to the job
without over-speeding the pump.
HYD-RK1520A Installer-Friendly Layout
- Suction runs are short and direct to protect inlet conditions and reduce
cavitation risk. - Perimeter room supports an unloader block, glycerin-filled gauge, and a short,
low-restriction bypass line back to tank. - Pressure and bypass lines route without tight radii that create heat and
friction losses. - Base deck offers clear mounting land, guard standoffs, and accessible fasteners
so first builds and fleet repeats follow a consistent pattern.
HYD-RK1520A What Is Included
- RK1520A triplex pump mated to a compact hydraulic motor on a shared, rigid
base. - Coupling, guard standoffs, and matched mounting hardware for a tidy,
professional assembly. - Concise startup checklist and torque guidance to standardize first installs and
future repeats.
What the Installer Provides
- Hydraulic power source and hoses sized for required flow, pressure, cooling,
and filtration. - Correctly rated unloader and secondary relief components for the chosen
working pressure. - Inlet strainer, supply hose, discharge hose, spray gun, wand, and nozzle set;
optional hose reel, surface cleaner, and chemical injection as needed. - Bypass return routed short and unrestricted to tank or suitable drain, below
fluid level to limit aeration.

Integration Checklist
- Size motor displacement to reach target pump RPM at available hydraulic flow:
RPM ≈ 231 × hydraulic GPM ÷ motor displacement (in³). - Confirm motor rotation and coupling engagement before opening the water supply.
- Set upstream hydraulic reliefs correctly and document final operating pressure
on the equipment decal. - Keep suction plumbing short, straight, and generously sized; avoid elbows at
the pump inlet and maintain a flooded suction whenever possible. - Provide a case drain if the motor requires it and route the line above
reservoir oil level. - Respect hose bend radii and clamp placement to avoid restriction, excess heat,
and premature hose fatigue. - Mount on flat structure, torque hardware in a cross pattern, and recheck
fasteners after the first hour of run time.
HYD-RK1520A Maintenance Routine
- Change pump oil on schedule; keep hydraulic oil clean, properly filtered, and
within temperature limits. - Inspect coupling wear surfaces, guard clearance, and base fasteners regularly;
re-torque after initial run-in. - Replace inlet screens and any high-pressure filters on a defined PM calendar.
- If performance fades, verify nozzle size, unloader setting, and suction supply
before opening the pump. - Rinse chemical lines at day’s end and never run the pump dry.
- For cold-weather storage, winterize with pump-safe antifreeze and tag the unit.
- Record service dates and pressure settings to standardize fleet maintenance
practices.
Operator Tips & Safety
- Choose nozzle orifice to hold working pressure under flow; oversize tips reduce
cleaning action and increase cycle time. - Use approved detergents at proper dilution, then flush with clean water to
protect valves and seals. - Keep suction airtight and as short as practical; starved inlets shorten seal
life and raise noise. - Stage reels and accessories so service access around the pump and motor remains
clear and safe. - Wear eye, hand, and hearing protection; purge air from lines, avoid deadheading
the pump, and pressure test after installation. - Log relief and unloader settings with date and technician initials to support
future diagnostics.
