The RW Series features a new pump frame ideal for long life belt drive pressure washers. The RW big bodied industrial pump has been engineered to run at 20 percent lower rpm. Featuring new state of the art low pressure seals that are impregnated with Teflon® and graphite, super thick ceramic plungers, super size 32 oz oil crankcase, over-sized tapered bearings for maximum life and load disbursement, double sight glasses, double oil drain plugs and special long life Ultra-form valve cage body that is impervious to absorption and deformation. Two models available RW21 1450 rpm 5.5 gpm @ 3,500 psi and RW15 1450 rpm 4 gpm @ 3,500 psi. The RW runs quietly and efficiently, ideal for long term pressure washing and contract cleaning.
Manifold: Forged Brass for strength and no porosity and long life. Higher hydrostatic pressures for safety and performance.
Bolts: Eight 10mm grade 8.8
Plungers: Are a special aluminum oxide blend, solid ceramic for long life, strong durability and more resilient. Ultra thick with SST retaining bolt.
Crankcase: Precision die-cast, large cross head for strength, large cooling fins and anodized (for maximum heat dissipation).
Bearings: Oversized for maximum life and load disbursement.
Valves, Seats, and Springs: Stainless steel with specially designed Ultra Form cages to provide long life and positive seating.
Seals and Packings: High pressure packings "V" style (D-1) and low pressure seals "Special profile" style (W-2) Buna-N (cotton duct weave base) strong and tightens under load. Top support ring.
Oil Seals: All are constructed of Buna-N rubber.
Plunger Rods: Stainless steel construction for strenght (no plating to scrape off), back-up and O-ring plunger sealing system.
Connecting Rods: Heavy 1-piece special alloy aluminum based, oversized for maximum strenght, load disbursement, and life. Heavy pin area construction, for added load strength.
Special Note: Use AR64516 Oil. First change oil after 50 hours of use, then after every 500 hours. This oil is specially formulated to provide correcct lubrication properties for our pumps. NO other oil is factory approved for these pumps.
