AR ANNOVI REVERBERI replacement left-hand pressure washer pump RMW22G24-EZ-SX 2400 PSI 2.2 GPM Easy Start

The AR Annovi Reverberi RMW22G24-EZ-SX is a left-handed replacement pump rated for 2,400 PSI and 2.2 GPM, designed with an easy-start valve and thermal relief to protect and simplify high-pressure cleaning tasks.

This RMW22G24-EZ-SX pump from AR Annovi Reverberi is built as a durable replacement for external motor pressure washers that need reliable pressure, convenient service features, and protection against overheating and overpressure. It combines brass fittings, an oil chamber, and a chemical inlet with a left-handed SX configuration so you can match it to compatible motors and start-ups while keeping maintenance simple.

How does this pump handle tough cleaning jobs?

The pump delivers up to 2,400 PSI at 2.2 gallons per minute, giving strong flow and pressure for a wide range of residential and light-commercial cleaning tasks. Its brass unloader and chemical outlet let you control pressure safely and add detergents when needed without extra adapters.

• Max pressure: 2,400 PSI (166 bar)
• Flow rate: 2.2 GPM
• Built-in brass unloader tip for excess pressure relief
• Chemical inlet for direct detergent suction

What features protect the pump and extend service life?

Several integrated features help prevent damage from heat and pressure, reducing downtime and costly repairs. The thermal relief valve automatically evacuates water if internal temperatures approach the safe limit, while the brass unloader prevents pressure build-up when the trigger is closed.

• Thermal relief activates near 140°F to discharge hot water
• Brass unloader allows safe pressure release to protect internal seals
• Easy-access oil chamber holds up to 2.2 ounces for lubrication
• Aluminum valve heads with serviceable components

How does the Easy Start (EZ) valve improve usability?

The EZ valve reduces the effort required to start the pump when residual pressure is present, so you can prime or restart without repeatedly pulling the trigger gun. This is especially helpful on systems with intermittent operation or when paired with a heavy-duty gun that holds pressure.

• EZ valve positioned ahead of the valve heads for convenience
• Starts pump despite built-up system pressure
• Reduces strain on starter motor and operator

How do I confirm compatibility with my motor and install it correctly?

Installers should identify left- vs. right-handed layouts by viewing the pump from behind with inlet/outlet facing up; the mounting leg hole indicates orientation. This RMW is an SX left-handed model with a 3/4" garden-hose style inlet and 22mm x 14 M outlet thread, so confirm mating fittings and shaft alignment before mounting.

• Pump type: SX left-handed configuration
• Inlet: 3/4" garden hose adapter
• Outlet thread: 22mm x 14 M
• Check mounting leg hole position to confirm left-handed fit

Who is this pump for? The AR Annovi Reverberi RMW22G24-EZ-SX is aimed at technicians, equipment rebuilders, and serious homeowners upgrading or replacing an external-motor pressure-washer pump. It suits users who need a dependable left-handed SX pump with thermal protection, an easy-start feature for smoother restarts, and provisions for detergent use—ideal for routine power-washing, fleet maintenance, and light commercial jobs where serviceability and protection matter.
