Inductive pump
An Inductive pump is a magnetically regulated positive displacement pump used to pump liquids and gases. It is capable of handling many corrosive chemicals as well as solvents and gases. It is characterized by a single piston that reciprocates within a magnetic field and therefore doesn’t require a dynamic seal to link the piston to an outside mechanical power source. Check valves are placed at both ends of the piston housing allowing the simultaneous suctioning and pumping that reverses with each stroke. This is known to reduce pulsations especially at higher flow rates. The piston and housing are constructed of materials that are inert to many liquids and gasses. Because the piston and housing are non-plastic materials the positive displacement chamber does not change in dimension from flexing and distortion thus allowing inductive pumps to remain very accurate with no significant changes over time. Inductive pumps are extremely accurate as each stroke contains the same volume created by a solid piston inside a solid chamber. The number of strokes can be counted or timed to determine the total volume delivered. They can be used in sterile and controlled environments as they will not leak to the outside of the housing even if the piston has experienced wear.
