Hydraulic piston pump

Work process just to make a small amount of supplement. Hydraulic piston pump can be operated single-well, you can also build gear type pump centralized management, a wide range of displacement adaptation, from tens to thousands of cubic meters per day, etc., suitable for deep, high-lift wells, heavy oil, inclined. The advantage is the displacement can be adjusted, from the convenience of parts for pumps tubing can not afford the operation and management. Pump efficiency up to 85%. The disadvantage is that the ground have to build a high-pressure pipelines, power fluid to be processed, an increase of well construction and management costs.
