Product Description

 API 11AX Sucker Rod Pump Valve Balls and Valve Seats 
 
 
We are  a pioneer manufacturer of balls and seats for rod-drawn sub-surface pumps. Special machines are used to lap each seat to a precise size and fit. Each ball and seat combination is vacuum tested on both sides of the seat and individually shrink wrapped and packed in a clear plastic container to seal out contamination and preserve the matched set from being separated. API specifications are met and exceeded for all balls and seats.

The following materials are available in ball and seat sets with the ball and seat being the same material or a combination of materials.
 
Cobalt, chromium and tungsten alloy with high corrosion and abrasion resistant properties. The ball hardness is HRC 58-61 and the seat hardness is HRC 52-56 and is essentially nonmagnetic. DuMore® is recommended for all hard pumping conditions with abrasive and corrosive fluids.







Tungsten Carbide is the hardest and toughest ball and seat material available. It has the best abrasion and impact resistance of all ball and seat materials and has good corrosion resistance. Nickel Carbide is almost as hard and tough as Tungsten Carbide and has better corrosion resistance. Titanium Carbide is offered as a ball material and has about the same hardness and toughness as Nickel Carbide with the same weight.

 Standard Stainless is the most popular ball and seat material due to its good corrosion resistance and economic price. It is made from 440C stainless steel and heat treated and tempered to a hardness of HRC 52-56. It is recommended for mild corrosion and abrasion in moderately deep wells.
 
 
The valve balls and valve seats are main components and parts of the sucker rod pump.
