• Speed: 3,400 RPM matched to common residential gas engines.
• Delivers stable output for wands, surface cleaners, and fan nozzles in its class.
• Supports light to medium-duty cycles when used within recommended run times.

Key Specifications

Designed around a 3/4″ hollow shaft and compact axial mechanism, this model
aligns with the mechanical envelope of many consumer and pro-sumer pressure washer
frames. Construction emphasizes corrosion resistance and low installed weight while
preserving structural integrity.

• Model: RQV25G30D-EZ3/8 axial plunger pump.
• Shaft type: 3/4″ hollow shaft for direct engine mounting.
• Outlet: 3/8″ quick-connect discharge for rapid hose attachment.
• Housing: Lightweight aluminum body with corrosion-resistant components.
• Start system: EZ Start feature to reduce startup back pressure.

Pump Design & Construction

The RQV25G30D-EZ3/8 uses a swashplate-driven axial plunger arrangement that
balances cost, performance, and package size for residential duty. The internal
pistons draw and discharge water in a compact layout, keeping the overall pump
light and manageable while still providing strong outlet pressure.

• Axial plunger mechanism for compact, efficient hydraulic output.
• Aluminum housing to reduce overall machine weight and ease handling.
• Corrosion-resistant internal components to withstand repeated wet operation.
• Internal geometry optimized for steady flow and controlled pulsation.
• Engineered as a stable core for homeowner and light-duty frames.

EZ Start & Quick-Connect Interface

To simplify real-world use, the pump incorporates both EZ Start and a quick-connect
discharge. EZ Start temporarily relieves internal pressure during ignition, making
pull-start engines easier to start and reducing mechanical strain. The integrated
3/8″ quick-connect outlet shortens setup time and removes the need for threaded
adapters.

• EZ Start helps prevent static back pressure at engine startup.
• Reduces pull effort and improves startup consistency.
• 3/8″ quick-connect outlet for fast hose and accessory changes.
• Limits thread wear and leak points associated with repeated connections.
• Streamlines daily setup and breakdown for residential users.

Operation & User Experience

In service, the RQV25G30D-EZ3/8 is intended to provide straightforward, predictable
performance. Once mounted to a compatible engine and properly plumbed, the pump
delivers steady pressure with minimal adjustment, while the EZ Start and quick
connection help keep operation user-friendly for non-technical operators.

• Consistent output suitable for general exterior cleaning tasks.
• Designed to work with common residential hoses, guns, and nozzles.
• Simple control scheme—no complex settings or auxiliary controls required.
• Reduced startup resistance improves overall user experience.
• Clear documentation supports initial setup and occasional adjustments.

Installation & Compatibility

The pump is intended as a direct replacement for units built around 3/4″
gas engine shafts operating in the 3,400 RPM range. When basic alignment and
mounting practices are followed, installation can be completed quickly by
experienced users or service personnel.

• 3/4″ hollow shaft interface for broad compatibility with residential engines.
• Direct-drive configuration eliminates belts and pulleys.
• Quick-connect outlet simplifies integration with existing hose sets.
• Supplied manual and schematic assist with mounting and connections.
• Suitable for replacement of many factory-installed homeowner pumps.

Applications & Use Cases

While compact, the RQV25G30D-EZ3/8 is capable of covering a wide range of
property maintenance and cleaning tasks. It is built for homeowners and light
operators who require reliable waterjet performance without moving to an
industrial platform.

• Driveways, sidewalks, and patios where surface soil and mildew accumulate.
• Siding, fencing, and decks needing periodic washdown.
• Vehicles, trailers, boats, and recreational equipment cleaning.
• Outdoor furniture, hardscape, and general property upkeep.
• Light to medium-duty projects in garages, workshops, and small facilities.

Maintenance & Service Practices

Day-to-day care for the RQV25G30D-EZ3/8 is focused on proper water supply,
correct startup procedure, and post-use flushing. With the crankcase pre-filled
from the factory, operators can concentrate on protecting seals, valves, and
internal surfaces from dry running and chemical residue.

• Confirm 3/4″ shaft compatibility and proper RPM before installation.
• Always open the water supply and purge air before starting the engine.
• Use EZ Start to limit startup stress on the pump and engine.
• Flush with clean water after detergent use to protect seals and internals.
• Employ pump saver or antifreeze solutions for off-season or cold-climate storage.
