RK21.20HNL AR (Annovi Reverberi) Pump 5.55 GPM @ 2900 PSI.
RK21.20HNL Plunger Pumps are designed for a wide variety of high pressure washing applications. They are constructed of die-cast bodies and feature a forged brass head. Internal components include special thick solid ceramic plungers for long life and durability. Precision cast cooling fins are anodized for maximum heat dissipation. Oversized tapered roller bearings and the precision supports assure proper shaft alignment and maximum life. Valve cages of special designed Ultra-Form provide positive seating and extended life. One-piece connecting rods are either a special alloy aluminum or bronze oversized for strength and load disbursement. These RK21.20HNL pumps are designed for gearbox , belt drive, or coupling drive systems, electric motor 182-184 frame driven systems, or gasoline engine driven systems.

Items NOT INCLUDED with your pump that you may need: Check out the accessories for this pump on the right hand side of the page! They can help keep your pump running properly!
The PUMP GUARD will 'dump' any water above 145 degrees F. before it reaches your pump (saving you the trouble of rebuilding your pump)
PRESSURE REGULATOR / UNLOADER - if we list one to the right of the pump this is the model we suggest you use with your pump. Other models with different features like adjustable or fixed and with / without chemical injector are available.
The INLET WATER FILTER will catch most small debris before it enters your pump
The EZ-START VALVE will remove the pressure on your motor when you first start your pressure washer, this item eliminates you pulling your trigger on your pressure washer gun when starting your pressure washer
The PRESSURE GAUGE KIT allows you to monitor what pressure you are operating your pump at! This is very important when you are cleaning delicate items like decks, fences and cars! It also helps you diagnose pressure problems with your pump!
PUMP OIL, you can never have enough on hand! Many pumps ship with oil already in them. But you should always have a bottle on hand so you can change your pump oil according to the manufacturers instruction.
