AR pumps have been a staple in the pressure washing industry since 1958. The Modena-based manufacturer makes everything from small diaphragm pumps for sprayers up to serious triplex plunger pumps. We’ve been fitting AR pumps to machines for years – they’re reliable and parts are readily available.
Why We Stock AR
Annovi Reverberi started out making agricultural pumps back in '58 and they've stuck to what they know. Their triplex pumps are workhorses - not the cheapest option but you're not replacing seals every few months either.
The RK and RKA series are popular with our commercial customers. Brass heads, ceramic plungers, proper oil bath crankcases. They also bought Ravel a few years back so they now make their own motors too.
What We Carry
We stock the most common AR pump models plus a full range of repair kits, valves, and seals. If you've got an older AR pump that needs parts, give us a ring - we can usually source what you need.
