RKV4.5G40HD Bare Pump 4.5 GPM @ 4000 PSI
AR Pump / Annovi Reverberi RKV4.5G40HD pressure washer pump 4000 PSI @ 4.5 GPM is a bare pump with no plumbing. You can use your old plumbing parts to save money. We highly recommend using a new unloader when installing a new pump. The VRT3-310EZ unloader valve is a great match up to this pump.
All pumps require both a primary pressure regulating device (i.e. regulator, unloader) and a secondary pressure safety relief device (i.e. pop-off valve, safety valve). Failure to install such relief devices could result in personal injury and/or damage to the pump and/or to the system components. We do not assume any liability or responsibility for the operation of a customers high pressure system.
