On the basis of the tubing pump, this kind of pumps have the ring valve device, thereby reducing the hydraulic impact, favorable pump valve open quickly, can resist gas interference, to prevent air lock, this pump is suitable for the higher oil and gas wells, used in high viscosity of crude oil in oil wells, the effect is better.
Features:
To quickly open the pump’s vavle;
To reduce the hydraulic hammer, can resist gas interference, to prevent air lock.
Applicable to oil and gas is higher and higher viscosity of crude oil Wells.
