    Abstract: A method for controlling operation of a pump unit, where the pump unit includes a primary piston pump having a primary piston and a secondary piston pump having a secondary piston. The primary piston pump is fluidically connected with the secondary piston pump. The primary piston pump includes an inlet valve and an outlet valve, and the pump unit operates periodically according to a pump cycle. The method includes determining a fluid pressure of fluid dispensed by the pump unit, and performing a closed loop control of a position of the primary piston in dependence on the fluid pressure of the fluid dispensed by the pump unit during a first time interval of the pump cycle.

    Abstract: One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump that utilizes an air efficiency device in order to optimize the amount of a compressed air in the pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings are achieved by minimizing the amount of required compressed air.

    Abstract: A piston and cylinder combination driven by linear motor with cylinder position recognition system, including a support structure forming an air gap; a motor winding generating a variable magnetic flow along part of the air gap; a cylinder having a head at one end; a piston connected to a magnet, the magnet driven by the magnetic flow of the motor winding to move inside a displacement path including at least partially the air gap; the displacement of the magnet making the piston reciprocatingly move inside the cylinder; and an inductive sensor disposed at a point of the displacement path of the magnet, such that when the piston reaches a position of closest approach to the cylinder head, the inductive sensor detects a variation in the magnetic field resulting from the corresponding position of the magnet, and generates a voltage signal arising from this magnetic field variation.

    Abstract: A control system and method for controlling electromagnetic drive pumps as, for example, electromagnetic driven membrane pumps are provided in which the control system is formed by at least one microprocessor and at least one sensor, whose microprocessor controls the power supply to at least one electromagnet whose changes in emitted magnetic field causes at least one moving part, directly or indirectly, to perform an oscillating pumping movement. The control system includes at least one positioning sensor which senses the moving part's position in the electromagnetic driven pump. By using the positioning sensor's measurements, the pump can be controlled with great accuracy.
