Abstract: Pump with plunger pistons comprising a head (1) in which are formed the intake and delivery ducts (2, 3) and the respective intake and delivery valves, a pump body (4) associated with said head (1) in which drive means (8) of at least one piston (6), and attachment and support means (5) of said pump body (4) at a body of the drive motor are situated, where said pump body (4) has, on the bottom wall (40), the seats (41) for the sliding of the pistons (6) and directly carries said attachment and support means (5) of the body of the drive motor and it is completely open on the edge facing towards the motor.
Abstract: Pump, comprising a casing that is generally cup-shaped intended to be fixed to a driving motor (3), and containing a drive shaft (6) suitable for being coupled with said motor, and having a tilted surface for the actuation of one or more pistons (7) that move parallel to the axis of said drive shaft, where said casing consists of a monolithic body (2) that comprises means (4) for its attachment to said motor, a system for supporting and holding said drive shaft, and the guide and sliding seats of the quoted pistons.

Abstract: An apparatus for cooling external environments, comprising a pump (5) which comprises an inlet conduit (7) destined to be connected to a water supply source, and a delivery conduit (9) connected to at least a nozzle (101, 201, 301, 401) for atomising the water, a motor (6) powering the pump (5) and a pressure regulator (11) for varying the water pressure delivered to the at least a nozzle (101, 201, 301, 401), in which the pump (5), the inlet conduit (7) and the delivery conduit (9), the pressure regulator (11) and the motor (6) are all housed in a casing (2) provided with a handle (3) and wheels (4), the casing (2) being conformed in such a way as to be transportable by a single person.
Abstract: Device for varying the delivery pressure of a jet washer comprising a positive-displacement pump operated by a single-phase electric motor powered by alternating current and having a delivery nozzle of predetermined cross-section, and electronic means for controlling and regulating the motor feed voltage to vary its speed of rotation.
