Abstract: A high-pressure plunger pump includes a plunger assembly having a working chamber and a plunger positioned in the working chamber that is movable in an axial direction, as we as first and second control valves connected to a valve housing having at least one high-pressure line and at least one low-pressure line, which are respectively connected to the working chamber by first and second control valves. The valve housing having a high-pressure connection that opens into the high-pressure line. The first and second control valves are actuable by a control unit in such a way that a fluid, which is fed via the high-pressure connection of the valve housing and is under high pressure, is fed to the working chamber and is dischargeable via a low-pressure connection of the suction valve after driving the plunger. The plunger is coupled to a generator via a driveshaft.

Abstract: The proposed method includes an initial checking step, during which a pump of a filtering circuit is operated at a given checking operation frequency meanwhile a pump checking operation value is measured, and using the measured data a calculation of the water flow rate when pump operates at a given operation frequency lower than the given checking operation frequency is performed. The pump is then operated at said given operation frequency for a first filtering period of time. When said period is concluded the checking step, at checking frequency, is newly performed obtaining a new checking operation value, and this value is used to calculate a required operation frequency necessary to produce a flow rate equal to the initially calculated flow rate, and the pump is operated at said new calculated operation frequency for a second filtering period of time.

Abstract: A system for flameless heating of a fluid includes a hydraulic pump having an input shaft and a rotational power source coupled in torque-transmitting relationship with the input shaft of the hydraulic pump. A hydraulic fluid circuit is in fluid connection with an inlet port and an outlet port of the hydraulic pump. A water heat exchanger having a tank provided with water from a water source and a conduit provided with heated fluid from at least one of the hydraulic pump and the power source is arranged such that heat is transferred from the heated fluid in the conduit to the water in the tank. In one example, at least one valve in the hydraulic fluid circuit selectively limits output flow from the outlet port of the hydraulic pump, thereby providing resistance to pumping motion and heating the hydraulic fluid in the hydraulic pump.
