Replacement pumps & pump matching
Engine or motor, shaft orientation and diameter, mounting, RPM, pressure, flow, inlet/outlet arrangement and unloader configuration all matter.
Pressure-washer compatibility & sizing
PressureWasherMatch.com is being built around a simple idea: identify what you have, verify the interfaces and operating limits that matter, and match the correct part or accessory before you buy.
Engine or motor, shaft orientation and diameter, mounting, RPM, pressure, flow, inlet/outlet arrangement and unloader configuration all matter.
Current CAT, AR/Annovi Reverberi, General Pump, AAA and Comet documentation exposes shaft, RPM, flow, pressure, ports, unloader and power differences that generic pump listings hide.
M22 interfaces, 3/8- and 1/4-inch quick connects, pressure and temperature ratings, gun inlet/outlet connections and proprietary brand systems are treated as separate compatibility checks.
Machine flow and target pressure determine nozzle orifice requirements. Spray angle is treated separately from orifice sizing.
Attachment diameter, nozzle count, hose/reel capacity, injector back pressure, unloader behavior and jetter-nozzle sizing all depend on machine flow, pressure and connections.
Pressure and flow solve different parts of the cleaning problem. Start with the work profile, required flow, heat and duty rather than a generic bestseller list.
Live compatibility hubs now separate current, legacy, proprietary and standard interfaces for RYOBI, SIMPSON, Kärcher, CRAFTSMAN, DEWALT, Greenworks, Sun Joe, Generac, Troy-Bilt and Westinghouse, plus a Honda-powered engine-to-pump guide.
A replacement pump can have similar PSI and GPM yet still be wrong because of shaft, RPM, mounting, orientation or unloader differences. A hose or gun can have the right-looking thread yet use a different subtype or rating. PressureWasherMatch.com will keep those distinctions visible.
Read the Compatibility Methodology for the evidence hierarchy and result-status system.
Start with the exact pressure washer, pump, hose, fitting or job requirement.
Check the interfaces, ratings, model generation and operating limits that actually govern compatibility.
Return verified, conditional, incompatible or unknown rather than forcing every combination into a yes/no result.
Show the technical basis first. Merchant options are presented only after the requirement is established.
The site helps match pressure washers with replacement pumps, hoses, fittings, guns, wands, nozzles, surface cleaners, foam cannons, hose reels, unloaders, downstream injectors and sewer jetters using manufacturer documentation and documented technical relationships.
No. Physical fit is only one part of compatibility. Pressure, flow, temperature, shaft or connection details, model generation and manufacturer documentation can all matter.
No. Compatibility and sizing conclusions are determined from technical evidence first. Merchant links are a separate layer and cannot change a technical result.
The site should show an unknown or conditional result rather than guessing. The goal is to explain what still needs to be checked before purchase or use.
