AR Pump XMA2.5G18E-F33 Pressure Washer 2.5GPM 1800 PSI 5/8" Shaft

Plunger Pumps are 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. These pumps are designed for gearbox, belt drive, or coupling drive systems driven by eletric motor or gasoline driven systems, gasoline engine driven systems.

WET END

Manifold:

- Forged Brass: Strength and no porosity equals

long life. Higher hydrostatic pressures, safety and

performance.

- Inlet and Discharge Ports: Heavy bosses for added

strength.

- Offset Discharge Ports: High efficiency, smooth

flow.

- Bolts: Eight bolts, 6mm, grade 12.9.

Valves:

- Ultra Form Cages: Durability, strength and long

life.

- Poppets, Seat and Spring: 303 and 400 series

stainless steel.

- Valve Caps: Machined brass – greater strength.

Packing and Plungers:

- High Pressure Packing: “V” style (D-1) Buna-N (cotton duct weave base) strong and tightens under load.

- Low Pressure Seals: “U” cup double lip Buna-N, good positive seal.

- Support Guides: Machined brass, two-piece construction to assure proper plunger alignment and to maximize packing and seal life.

- Plungers: Are a special aluminum oxide blend, solid ceramic for long life, strong durability and more resilient.

DRIVE END

Bearings: Oversized for maximum life and load disbursement, needle bearing on the drive side and ball on the non-drive side. Each bearing is held in position on the crankshaft and crankcase by snap rings. This assures positive alignment and centering of the connecting rods and crankshaft in relation to the crankcase, it also eliminates the crankshaft from floating.

Crankcase: Precision die-cast, large cooling fins and anodized (for maximum heat dissipation).

Rear Cover: precision die-cast, O-ring sealed and bayonet style sight glass for positive sealing and locking (no threads to loosen).
