American Manufacturing - 4.5" x 5" FF-AXFM

<back

Duplex Power Pump

The American Model FF-AXFM is a duplex reciprocating type power slush pump designed for maximizing volume without sacrifice of working pressure and compactness.

Its power end is a rugged, one-piece unit with integral supports for jackshaft and eccentric shaft bearings. The cover is removable for easy access to the power end components.

Connecting rods are one-piece cast alloy with renewable eccentric bushings and crosshead bushings. The one-piece skirt type cast alloy crosshead is reinforced at all load areas.

Fluid end of the FF-AXFM is a one piece casting with conventional pot type valves. Steel studs secure valve covers, flangesand plates to the fluid end, and fluid end to power end.

All bearings are sealed in individual pressure gun lubricated housings. Eccentrics, crossheads and pins are lubricated from the power end reservoir through normal movement of parts.

American lubricator type packing glands provide positive lubrication to piston rods. This pump is equipped with American pistons, hardened liners, rods and valves.
