AR Pump XMA3G25N Pump: 3/2500 1750RPM 8.715-307.0

Description

Features

• 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.
• 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).
• Plunger Rods: Stainless steel construction for strength (no plating to scrape off). O-ring plunger sealing system.
• Rod Pins: Precision ground and hardened steel, oversized for load disbursement.
• Connecting Rods: One-piece special alloy aluminum based, oversized for maximum strength, load disbursement, and life. Heavy pin area construction, for added load strength.
• Crankshaft: Forged, precision ground and hardened for extremely long life and durability.
• Oil Seals and O-rings: All are constructed of Buna-N rubber. The O-rings have stainless steel garder springs to assure constant tension on the sealing surface.
• Oil Capacity: 14.5 oz., refer to parts breakdown.
• Dyno Proven: All pumps are dyno tested to assure the theoretical design meets the actual design.
• Valve Design: Each pump series has a valve design that optimizes its highest efficiency.
• Hot Water: High temperature kits are available to 180º F. Refer to breakdown
• Wet End Repair: Very simple no special tools are required.
• Mounting Bolt Pattern: Same on the top and bottom of the crankcase for simple drive side change.
• Design: Using advanced fluid handling design programs. Overall pump efficiency is increased.
