AR Pump SRG1535N Pump: 4/4000 1450 RPM

Manifold: - Forged Brass: Strength and no porosity – long life. higher hydrostatic pressures – safety, performance. - Inlet and Discharge Ports: Heavy bosses for added strength. - Offset Discharge Ports: High efficiency, smooth flow. - Bolts: Eight bolts, 8mm, grade 8.8. • Valves: - Machined brass - Ultra Form Cages: Durable, strength, and long life. - Poppets, Seat and Spring: 303 and 400 series stainless steel. • 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 for a good positive seat. - Support and Guides: Machined brass, 1-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 tapered roller bearing for maximum life and load disbursement. • Bearing Support: Precision die-cast and machined to assure concentricity and alignment. • 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), back-up and O-ring plunger sealing system. • Rod Pins: Precision ground and hardened steel, oversized for load disbursement. • Connecting Rods: One-piece special allow aluminum or bronze for higher pressure, 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: Triple lip oil seals, long life and much less leak prone. All are constructed of Buna-N rubber. The O-rings have stainless steel garder springs to assure constant tension on the sealing surface. • Oil Drains: Quantity of two (2). One in the rear cover and one in the bottom of the crankcase. • Oil Capacity: 15.5 oz. • 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.
