In oil extraction, what we often call a piston pump is actually a rod pump that everyone is familiar with-it is the core equipment of underground oil production, relying on the “reciprocating movement of the piston” to extract underground crude oil. The principle is simple but the function is critical. The API 11AX Tubing Pump, which we focus on selling, as a benchmark product in petroleum rod pumps, has taken the advantages of this operating principle to the extreme, and cooperated with the tube pump to form a complete oil recovery system.

In oilfield oil production equipment, the stroke length of the rod pump is the key indicator that determines the efficiency of oil production, but it is often misunderstood by newcomers in the industry.
