Abstract: A diaphragm metering pump having control over diaphragm extension is described. A position sensor is incorporated in a diaphragm metering pump to indicate the relative position of the diaphragm during flexure. When excessive extension of the diaphragm is sensed by the position sensor, a control valve will provide hydraulic fluid from a reservoir for inhibiting further deflection of the diaphragm in the direction in which it was moving. Diaphragm life is extended as well as the accuracy of metering provided by the pump maintained.

Abstract: A variable-speed drive controller and associated methods are disclosed for reciprocated lifting systems, particularly long-stroke, fluid-pumping systems such as certain oil-producing equipment. A variable-speed drive is controlled through an electronic feedback loop by a programmable controller, which varies the speed of the drive when sensors detect the passage of the reciprocating mechanism. The controller can be set to slow the drive when the reciprocating mechanism reaches the end of the stroke, to permit faster production of fluid without increased mechanical wear on the reciprocating mechanism or increased stress on the lifting string. The controller also can be set to slow the drive on the downstroke, such as to permit faster production of fluid when pumping viscous liquid.

Abstract: A liquid feed pump which increases the liquid flow velocity in a stagnation area in the pressure chamber of a plunger pump, thereby improving the liquid replacement speed in the plunger pump. When the liquid in the liquid feed pump is replaced, a first plunger slides back and forth in the space between a lower limit point and an upper limit point, and the second plunger stops at least temporarily at a position near to the upper limit point or slides back and forth for a shorter distance than when the liquid feed pump usually feeds the liquid.

Abstract: A high pressure pump including a linear actuator having a servo motor to axially rotate a hollow rotor shaft in alternating directions, the servo motor having a stator positioned co-axially around the hollow rotor shaft with an interior of the rotor shaft being co-axially coupled to a drive member to convert axial rotation into reciprocal displacement, the drive member being constrained against linear movement and supporting a shaft. At least one piston is coupled to the shaft and the piston is arranged within a cylinder to define a pumping chamber, whereby alternating rotation of the rotor shaft causes reciprocal linear displacement of the piston to pressurize fluid in the pumping chamber. A drive mechanism includes a controller coupled to a servomotor and an encoder to measure movement of the hollow rotor or output shaft and send a feedback signal proportional to the movement to the controller.
