Don-Nan One-Piece Insert Guided Cage

Of all the massive parts on the pump assembly, when the balls, seats, and cages get beat-out, pump failure is soon to follow. While a carbide insert preventing beat-out may be conventional today, the One-Piece Insert Guided Cage is unconventional. With four-pieces susceptible to breaking, the One-Piece Insert Guided Cage is four pieces inertia-welded together to add long-lasting durability to the cage and, most of all, your pump.

Don-Nan (patented) Sand Diverter

With solids in the well tearing plungers up, the patented Don-Nan Sand Diverter provides an alternative to scored plungers and short run-times. This spray-coated plunger adaptor has a larger O.D. than most all other plunger adaptors with an extra tight clearance. The upper ports allow for sand to enter the plunger I.D. rather than accumulating on the outside of the plunger, thereby minimizing any abrasion or scoring on the plunger. Ask about the patented Sand Diverter and work towards keeping the pump downhole.

Don-Nan OverSized Cage

This big Kahuna provides a larger diameter for increased fluid flow without having to alter the pump bore. The only alteration required is the use of a Don-Nan Type O Mandrel for the hold-down. Given the same pump, a standard API cage seat of 1.75" can be upgraded to a 2" seat by using the Don-Nan Oversized Cage. By increasing fluid flow, fluid turbulence is decreased minimizing gas break and all issues associated with gas. And to aid potential beat-out, internal ball guides are cut into the cage to minimize chaotic ball movement. Ask about the Don-Nan Oversized Cage.
