    Abstract: A liquid pumping apparatus for pumping liquids, more specifically a linear peristaltic pump apparatus. The apparatus consists of a high durometer compressible elastomeric liquid flow tube (12), an infeed valve assembly (26), an outfeed valve assembly (38), an extensible and retractable actuator anvil (34) having a round surface which engages the flow tube (12) at all times, an opposed anvil (24.1) having a round surface in engagement with the flow tube at all times, the flow tube being held between the anvils (34, 24.1) in a slightly compressed state when the anvil (34) is retracted, and a control assembly (100) for causing the movable anvil to be sequentially extended and retracted to cause flow within the flow tube (12) from the infeed valve assembly (26) to the outfeed valve assembly (38). With this apparatus the lumen of the flow tube (12) to the sides of the anvils is not completely reduced to zero volume during displacement compression whereby gas embolisms do not erupt or explode when discharged. Two principal embodiments are disclosed, one having infeed and outfeed check valves which oclude the flow tube, and the other having check valves.

    Abstract: A reciprocating pump includes a housing (12) having an annular passage extending therethrough between opposed open ends, and a piston (22) is disposed within the annular passage between glands positioned at each open end. A pressurizing chamber assembly is disposed at each housing end and includes a chamber head that is attached to respective housing ends. A pressurizing member is disposed within each chamber head and is attached to respective opposite ends of the piston. The pressurizing member, and an inside surface of a respective chamber head, form a pressurizing chamber therebetween. The pressurizing member is of a one-piece construction, having a solid nose portion (18) and a hollow skirt (104). The hollow skirt has a flanged end that is interposed between a respective chamber head and housing end to form an air- and liquid-tight seal therebetween.

    Abstract: A reciprocal type of pump or motor structure wherein a piston (21) has a linear function actuated by a pair of coils (30, 31) energized alternately and in the pump structure a check valve (39) in an outlet of the structure which stretches to open said outlet under the impact of expelled fluids and of its own volition retracts to the closed position immediately upon the cessation of fluids being expelled.

    Abstract: A metering pump comprises a drive unit (1) and a pump head (11), into and from which fluid which is to be metered can be sucked from an input line via a first non-return valve (17) or can be expelled to an output line (20) via a second non-return valve (19). The drive unit comprises a control organ (2) which, on the basis of electrical control signals, controls a force-applying fluid or an actuating flow inside the drive unit so as to regulate movements of the pump. The pump head comprises a working space (16) and an expulsion organ (12) capable of interacting with the fluid which has been sucked into the space, said expulsion organ in the course of a space-reducing movement in the pump head expelling the sucked-in fluid into the output line. Part of the total space-reducing movement of the expulsion organ is reserved for compressing the fluid sucked into the space before the expulsion movement begins. At the metering of fluid including gas bubbles, the metering pump makes accurate metering processes possible.

    Abstract: A monitoring system may include a position sensor, strain gauges, and a computing device for monitoring valves in a pressure pump having multiple chambers to determine critical valve limits for the valves using strain measurements for each charmber. The strain gauges may determine strain in each chamber of the pressure pump. The position sensor may determine the position of a crankshaft mechanically coupled to a plunger in each chamber. The computing device may receive signals generated by the strain gauges and the position sensor related to the strain in each chamber and the position of the crankshaft, respectively, and may process the signals to determine delays in the actuation of the valves for determining critical valve limits.
