  • Piston pump having housing with a pump housing and a pump assembly drive housing formed therein
    Patent number: 6599107
    Abstract: A fluid pump for pumping a volume of fluid under pressure from a fluid source to a fluid dispenser includes an electric motor. A pump drive assembly is operably coupled to the motor for reducing an output of the motor. A pump assembly is operably coupled to the pump drive assembly and is fluidly communicable with the source of fluid, the pump assembly being actuated by the pump drive assembly, the actuation causing the pump assembly to pump the fluid. A single main housing, the main housing in part the pump drive assembly and having a pump housing defined therein, the pump housing being integral, unitary therewith for housing the pump assembly. A method of making a fluid pump for pumping a volume of fluid under pressure from a fluid source to a fluid dispenser.

  • Switch for controlling the motor of a piston pump
    Patent number: 6419456
    Abstract: A fluid pump having a motor operably coupled to a pump assembly, the motor and pump assembly acting cooperatively to pressurize a fluid includes a pressure switch being in communication with the fluid under pressure and being in communication with the motor for sensing the fluid pressure and controlling the operation of the motor to maintain a selected fluid pressure. A method of controlling fluid pressure in a fluid pump, the fluid pressure being generated by activating a pump motor to operate a pump assembly.
