摘要： A positive-displacement pump (10) of the type comprising a driving gear (12) and a driven gear (14) perfectly coupled together and each mounted on a respective support shaft (16, 18). The driving gear (12) is operatively connected to a motor (20) to set the driven gear (14) in rotation and generate the pumping action on a fluid. The gears (12, 14) are contained in a chamber (40) provided with a closing plate (42). The support shafts (16, 18), the central body (38) of the pump (10), the chamber (40) that contains the gears (12, 14), the closing plate (42) of such a chamber (40), an inner magnet (36) and the base of the rear body (28) of the pump (10) are in turn housed inside a casing (30) of the pump (10).

摘要： An improved screw-spindle pump, particularly for cooling systems, includes a first screw, a second screw and a pump housing, inside which the first screw and the second screw are rotatably housed between the first screw, the second screw and the pump housing, being defined pumping chambers adapted to move, as a consequence of the rotation of the first screw and the second screw, a fluid from a suction area to a delivery area of the pump.
The pump housing housing the first screw and the second screw is made in one piece.

摘要： A pump particularly for pumping a liquid such as ink, paint, glue or the like, includes at least one rotating pumping member having a respective shaft. The at least one rotating pumping member being at least partially housed inside a pump body, the shaft being rotatably supported by at least one support associated with the pump body.
The shaft has on its external cylindrical surface in contact with the liquid one, or more recesses, or the at least one support includes on its internal cylindrical surface in contact with the liquid, one or more recesses.

摘要： A pump particularly for pumping abrasive and/or chemically aggressive liquids includes at least one rotating pumping member having a respective shaft, the at least one rotating pumping member being at least partially housed inside a pump body. The shaft is rotatably supported by at least one support associated with the pump body.
The shaft and the at least one support are both at least partially made of a material having a hardness greater than or equal to 5 Mohs, where the material having a hardness greater than or equal to 5 Mohs is located at least in the areas of the shaft and of the support in mutual contact.
