Forced open close inclined well pump by virtue of the thrust of the spring, the valve ball is forced to set in the valve seat sealing surface, make the pump can work normally even under the conditions of horizontal status, which solves the problem that the valve ball can't back to seat by gravitational force under the inclined or horizontal work status,.
This kind of pumphas simple structure, reliable performance, low operation cost, high pump efficiency, etc. which is widely used in deviated well and horizontal well production.
