A lease automatic custody transfer (LACT) system includes a pump assembly and meter system. The pump assembly is configured to pump a volume of fluid out of a storage container into a conduit. The pump assembly causes a pulsating flow of the volume of fluid through the conduit. The meter system is coupled to the conduit and includes a meter device and a processing system. The meter device is configured to obtain a plurality of measurements corresponding to the volume of fluid flowing through the conduit. The processing system is communicatively coupled to the meter device and configured to determine a flow parameter value based on the plurality of measurements.

A fluid pump includes: three or more volume chambers that suction and discharge a fluid sequentially; moving elements that are respectively provided in the volume chambers, move relative to the volume chamber, and suction and discharge the fluid from and to the volume chamber; a cam that abuts against and drives the moving elements; and a driving section that drives at least one of the moving elements and the cam and relatively rotates the moving elements and the cam to discharge the fluid one time from each of the volume chambers in one cycle of the relative rotation, in which, when suctioning and discharging the fluid, regarding a discharge rotation angle α, α=(Z/M)×N is satisfied, where the number of volume chambers is M and any integer from 2 to (M−1) is N.

A four-cylinder diaphragm pump includes a pump body having four pump chambers, and a drive mechanism that expands and contracts the four pump chambers with a predetermined phase difference, in which the pump body includes a first diaphragm having two diaphragm portions on a same plane, and a second diaphragm having two diaphragm portions on a same plane disposed to be located to be parallel to or coplanar with the plane of the first diaphragm, each of the diaphragm portions of the first diaphragm and the second diaphragm constitute a portion of a different pump chamber, and the drive mechanism is configured to move the diaphragm portions of the first diaphragm and the second diaphragm forward or backward with respect to the corresponding pump chambers with a predetermined phase difference.

A hydraulic system has two hydraulic circuits, each with a pressure generating unit acting on an actuator unit. The generating units are slot-controlled radial piston pumps and form a pump assembly with a single common pump support and single common rotor. The rotor is rotatable on a free protruding section of a common support hub and has piston-receiving bores on axially offset planes. The hub has two first and two second fluid bores. The first bores communicate with first pump connections and first control openings on the hub on a first plane, and the second fluid bores communicate with second pump connections and second control openings on the hub on a second plane. A first and a second adjustment frame, each having an eccentric ring and acting on the pump pistons, are disposed on respective planes perpendicular to the main axis and independently guided in a linearly movable manner.

It is disclosed a method for reducing the pulsation level in a multi-compressor plant where each compressor of a plurality of compressors is driven by a respective motor. The method manages to reduce the pulsation level by starting a first motor of a first compressor and then starting in succession each one of the other motors in a way to synchronize all motors between each other with a specified phase shift.

A portable hydraulic power unit includes a frame, a fluid tank supported by the frame, and a manifold supported by the frame. The fluid tank is configured to store a supply of hydraulic fluid for powering a hydraulically-driven tool. A reciprocating pump is mounted on the exterior of the fluid tank and on the exterior of the manifold. The reciprocating pump is secured to the fluid tank and the manifold with fasteners extending through a cylinder body of the reciprocating pump.

A diaphragm pump system that includes a pair of working fluid diaphragm pump assemblies that are each fluidly connected to a working fluid flow. Each working fluid diaphragm pump assembly is operationally associated with a discrete drive arrangement that is fluidly isolated from the working fluid flow that is moved during operation of the pump system. A control arrangement is connected to the discrete drive arrangements and configured to control the cyclic operation of the pair of working fluid diaphragm pump assemblies to mitigate pulsatile effects in the combined working fluid flow when the discharges of the working fluid flows associated with operation of the pair of working fluid diaphragm pump assemblies is combined.

In one embodiment the method of making a food product comprises feeding a liquid composition into a cavity, the liquid composition comprising at least 80% liquid egg comprising albumen and yolk; mixing the liquid composition in the cavity; raising the temperature of the mixed liquid composition to above 175° F.; and after raising the temperature, extruding the mixed liquid composition through a die cavity having a temperature greater than 175° F. to solidify and shape the mixed liquid composition into a solid composition; and cutting the solid composition to a desired length.

A pulsation damping system for reducing pressure oscillations in an inlet line and/or in an outlet line of a piston pump. The piston pump includes a pump chamber which is connected to the inlet line of the piston pump via a first fluid connection and to the outlet line of the piston pump via a second fluid connection to convey a conveyance fluid. The pulsating damping system includes a damping device. The pump chamber includes a damping fluid connection via which the pump chamber is fluidically connected to the damping device to damp the pressure oscillations.
