Valve Ball & Seat

The ball-and-seat assembly in a subsurface pump probably undergoes more severe service on a continuous basis than any other component in the pump. No pump part is more critical since even a slight amount of wear on the ball or seat will cause an immediate loss of pumping efficiency.

Sanjack pump quality begins with the careful selection of materials for each grade of ball and seat to meet the intended service conditions. Before packaging, each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.

Sanjack ball-and-seat valves are made to meet or exceed the API 11AX Specification.
