Structures Of Non-Positive Displacement Pumps

Abstract
New drive system for impeller pump drives characterized by being formed by a tubular head bearing housing a helical spring that exerts constant pressure on a steel ball that seals the outlet whose spring stops exerting pressure thanks to the pressure produced by the liquid to be this driven by the pump that is constituted by a support that holds the body soprote of intake which is a carrier inside a helical recoil spring that serves to maintain at all times the pump in its aspirant position.
