SRMW23G28-EZ 2.3 GPM 2800 PSI | 3400 RPM EZ-start vertical pump

SRMW23G28-EZ Reinforced Vertical Axial Cam Pump

The Annovi Reverberi SRMW23G28-EZ is a reinforced vertical-drive axial cam pump
engineered for gas-engine pressure washers that need reliable output and low
daily maintenance. Operating at 3,400 RPM, it delivers a steady
2.3 GPM at 2,800 PSI, providing strong cleaning power in a compact
package for residential, agricultural, and light commercial tasks.

• 2.3 GPM at 2,800 PSI for demanding medium-duty cleaning tasks.
• Reinforced SRMW heavy-duty design for extended service life.
• Vertical axial cam layout optimized for compact gas engine platforms.
• Maintenance-free synthetic oil crankcase for reduced service requirements.
• Integrated safety and control features to protect the pump and engine.

Performance & Duty Point

The SRMW23G28-EZ is sized for high-output homeowner units and light-duty contractor
machines that operate frequently but do not require full industrial triplex
architecture. The combination of 2.3 GPM and 2,800 PSI
produces strong jet energy for concrete, siding, and equipment cleaning while
keeping water consumption at a practical level for portable systems.

• Flow: 2.3 GPM for efficient rinsing and coverage.
• Pressure: 2,800 PSI for aggressive removal of typical soils.
• Speed: 3,400 RPM matched to common small gasoline engines.
• Duty range well suited to frequent seasonal use and light commercial workloads.
• Designed to support standard hose, gun, and nozzle sets on consumer and pro-sumer machines.

Vertical Architecture & EZ Start Interface

This model is configured with a 7/8″ vertical shaft for direct
mounting to compatible gas engines. The vertical axial cam layout keeps weight low
and simplifies cart and frame design. Integrated EZ Start technology
reduces resistance at startup by relieving static back pressure, making pull-start
engines easier to fire in real-world use.

• 7/8″ vertical shaft interface for direct engine mounting.
• Compact form factor for consumer carts and light commercial frames.
• Axial cam design for low weight and reduced packaging complexity.
• EZ Start feature to reduce pull effort during engine startup.
• Improved user experience when starting engines under load.

Engine & Frame Integration

The SRMW23G28-EZ is intended as a direct replacement or upgrade for vertical-shaft
portable pressure washers. Its mounting pattern and shaft specification align with
popular small-engine models, allowing service centers and OEMs to restore or build
units without redesigning frames or guards.

• Direct-fit solution for many vertical-shaft gas engine platforms.
• Reduces the need for adapters, spacers, or additional brackets.
• Helps maintain original equipment ergonomics and hose routing.
• Suitable for both replacement work and small production runs.

Integrated Protection & Controls

The SRMW23G28-EZ incorporates core control and protection functions directly into
the pump body. An integrated unloader manages system pressure and bypass flow, while
a factory-installed thermal relief valve (TRV) helps protect seals
and internal components during extended bypass operation. A built-in detergent
injector adds chemical capability without external proportioning hardware.

• Integrated unloader for regulating working pressure.
• Factory-installed TRV to relieve overheated water in bypass mode.
• Built-in soap injector for downstream detergent application.
• Reduced external fittings and components compared to stand-alone accessories.
• Protection and control functions engineered as part of the pump assembly.

Unloader, TRV & Detergent Injection

In operation, the unloader diverts flow back to bypass when the trigger gun is
closed, preventing dangerous dead-head conditions. The TRV automatically vents hot
water generated during long bypass periods, guarding internal elastomers and
components. The detergent injector draws chemical into the low-pressure stream,
enabling soap application for heavy soil and grease removal.

• Automatic bypass function when the spray gun is released.
• Manual pressure adjustment to match delicate or heavy cleaning tasks.
• TRV-driven temperature control during prolonged idle or bypass.
• Chemical injection capability without additional pumps or mixers.
• Simplified plumbing for OEMs and service technicians.

Maintenance, Serviceability & Crankcase Design

The crankcase is factory-filled with synthetic oil and sealed for the life of the
pump under normal operating conditions, removing routine oil changes from the
maintenance plan. While the drive end is maintenance-free, the wet end remains
serviceable with available seals, valves, and repair kits, extending the useful life
of the unit beyond its initial service window.

• Maintenance-free synthetic oil crankcase—no scheduled oil changes.
• Reduced service burden for homeowners, landscapers, and small contractors.
• Serviceable wet-end components for seal and valve replacement when required.
• Documentation and schematics typically supplied for troubleshooting and repair.
• Lifecycle strategy based on minimal daily maintenance and planned rebuilds.

Applications & Use Cases

With its reinforced construction and integrated control features, the SRMW23G28-EZ
is suited to a broad range of cleaning tasks where portability and consistent
performance are important. It bridges the gap between basic consumer pumps and
full industrial triplex units, making it a solid choice for serious residential
users and light commercial operators.

• Residential cleaning of siding, decks, patios, driveways, and fences.
• Light commercial storefronts, sidewalks, and small building exteriors.
• Vehicle and small fleet washing for cars, pickups, ATVs, and trailers.
• Agricultural equipment cleaning for tractors, implements, and shop tools.
• Property maintenance work for landscapers, contractors, and facility teams.
