RCA2.5G25N PUMP by AR (6658)

The RCA25G25N is a commercial triplex plunger pump designed for a wide variety of high- pressure washing applications. They are constructed with die-cast bodies and feature a 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 needle bearings on the drive side, and ball on the non-drive side together with the precision supports assure positive alignment and centering in relation to the crankcase. Valve cages of special designed Ultra-Form provide positive seating and extended life. Ball bearings on both sides of solid shaft drive pumps. One-piece connecting rods are special alloy aluminum, oversized for strength and load disbursement.
