Abstract: PROBLEM TO BE SOLVED: To provide a magnetic drive metering pump of simple and low-cost structure provided with variable and more larger operation range by solving a well-known fault related to hydraulic performance in a metering process. SOLUTION: In this magnetic drive metering pump, a reference element is related to a module comprising thrust members and a connecting rod. A position sensor detects position of the reference element, and the position sensor provides a real signal fixed to the position of the reference element. Movement of a unit formed by the thrust members and the connecting rod receives the influence to follow the predetermined nominal profile with a view of control accuracy through a control circuit.

Abstract: Provided for may be a motor speed control apparatus for use with a piston pump. The piston may be adapted to create a plurality of compressions and the piston may have a compression path and a decompression path. Further, the piston cylinder may include a proximal end, a distal end, and a piston length. The piston cylinder may have a proximal threshold position and a distal threshold position. In an embodiment, the apparatus includes a proximal and a distal hall effect sensor. The apparatus may comprise a computer, wherein instructions instruct the piston to decelerate at the distal threshold position during the compression path and the proximal threshold position during the decompression path, and/or wherein the computer executable instructions instruct the piston to accelerate at the distal threshold position during the decompression path and the proximal threshold position during the compression path.

Abstract: A double-action piston pump of an application system for applying a fluid medium to a substrate, wherein the piston pump has a piston which is movable between a first reversal point and a second reversal point for delivering the fluid medium, wherein on reaching the first reversal point and the second reversal point, the movement direction of the piston is reversed, wherein during an output period, the fluid medium is output by means of an output device, and during an interruption period, an output of the fluid medium by means of the output device is interrupted, wherein during the interruption period, the movement direction of the piston is reversed, wherein on reversal of the movement direction during the interruption period, the piston is situated at an intermediate position between the first reversal point and the second reversal point.

Abstract: A method for operating a construction-material and/or viscous-material pump for conveying construction material and/or viscous material has the steps of: a) determining a required value of a power or of a size of the motor system, corresponding to the power, for moving the conveying piston, b) setting, on the basis of the required value, a speed value of the motor system in such a manner that a power and/or speed reserve value between an operating point, wherein the operating point is defined by the required value of the power or of the size and the speed value, and a characteristic curve of the motor system, wherein the characteristic curve is defined by maximum values of the power or of the size and speed values, wherein maximum values are different for different speed values at least in sections, is greater than or equal to a reserve limit value.

Abstract: Methods and systems are provided to adaptively control a hydraulic fluid supply to supply a driving fluid for applying a driving force on a piston in a gas compressor, the driving force being cyclically reversed between a first direction and a second direction to cause the piston to reciprocate in strokes. During a first stroke of the piston, a speed of the piston, a temperature of the driving fluid, and a load pressure applied to the piston is monitored. Reversal of the driving force after the first stroke is controlled based on the speed, load pressure, and temperature.

Abstract: Devices and methods for operating a diaphragm compressor system provide high output pressure and high throughput. In some embodiments, modular diaphragm compressors are stacked with a clamping mechanism pressing the compressor modules together. In embodiments, multiple stacks are provided as stages of a pressurization process. In embodiments, a main stage valve controls one or more pressure circuits for one or more hydraulic actuators of compressor modules. In embodiments, orifices configured for damping are incorporated to control actuator piston movement within a compressor module.
