    Abstract: A pump system comprises an electric motor, a pump, a converter and a controller. The electric motor has a rotational output shaft that is rotatable in a first rotational direction and an opposite second rotational direction. The pump has a linearly displaceable input shaft that is movable in a first linear direction and an opposite second linear direction. The converter couples the output shaft to the input shaft such that rotation of the output shaft in the first rotational direction translates the input shaft in the first linear direction, and rotation of the output shaft in the second rotational direction translates the input shaft in the second linear direction. The controller repeatedly reverses rotation of the output shaft to produce reciprocating motion of the input shaft.

    Abstract: The present invention relates to a spray gun for the expulsion of a fluid, with at least one cylinder (1) in which a piston (2) is mounted movably, the cylinder (1) having formed in it a fluid chamber (3), the volume of which can be varied by means of a movement of the piston (2) and in which at least one first cylinder orifice (5) is formed, and a spray orifice which is connected to the first cylinder orifice (5) of the cylinder (1) via a connecting line (20), so that a fluid, which is received by the fluid chamber (3) and is pressed out through the first cylinder orifice (5) by the pressure exerted by the piston (2), arrives via the connecting line (20) at the spray orifice and is expelled there. The spray gun according to the invention is distinguished by the fact that a fluid valve (21) is arranged in the connecting line (20), and, in the cylinder (1) a sensor (29) is provided, by means of which a defined position of the piston (2), in which fluid is still located in the fluid chamber (3) during the expulsion operation, can be detected, and by means of which the fluid valve (21) can be actuated, the fluid valve (21) being closed by means of the sensor (29) when the defined position of the piston (2) has been detected. The invention relates, furthermore, to the use of such a spray gun for the expulsion of plant protectants.

    Abstract: A pumping unit for a machine to distribute concrete includes a pair of cylinders provided with a relative pumping piston movable linearly for a determinate travel to feed the concrete to a determinate circuit to distribute the concrete; and a hydraulic command circuit operatively connected to both the cylinders, to determine an alternate pumping movement of the relative pumping pistons. The pumping unit includes at least a sensor member operatively associated to at least one of the cylinders in order to detect point-by-point one or more data relating to the operating condition of the pumping piston during its movement for the whole travel. The data includes at least one of position, speed, stress and direction of movement of the relative piston.

    Abstract: A system for cooling and recuperative heating of a slurry in a metallurgical process which includes heat exchangers, pumps and autoclaves is described herein. The heat exchangers use a non-scaling common liquid heat transfer medium. Preferably, the heat exchangers are tube-in-tube heat exchangers with 3 to 7 slurry tubes in each heat exchanger. An advantage of this system is that it does not use flash tanks. To minimize abrasive wear on impinged surfaces, the velocity of the slurry is not more than 5 meters per second. The slurry comprises a solids concentration of 25% to 50%. Preferably, the pumps in the system are float-type pumps in which the driven liquid from the discharge pumps is also used as the drive liquid for the feed pumps.
