1. Upward stroke: When the plunger of the heavy oil recovery downhole pump moves upward, the upper liquid enters the lower chamber through a specially designed feedback channel to form hydraulic energy storage. 2. Downward stroke: The stored hydraulic energy is converted into auxiliary thrust (actually measured up to 2-5kN), and the super heavy oil injection and production downhole pump can effectively overcome the resistance of heavy oil. 3. Pressure balance design: The heavy oil pump with hydraulic feedback uses our original two-way flow channel structure to balance the pressure inside and outside the pump in real time to avoid air lock and sand jam.

Specifically designed for heavy oil and high gas-cut wells. The mechanical forced-opening mechanism ensures the valve opens/closes on every stroke, regardless of fluid viscosity.
