Abstract:
A fluid pump having a motor operably coupled to a pump assembly, the motor and pump assembly acting cooperatively to pressurize a fluid, comprising:a pressure switch arrangement, the pressure switch arrangement being in communication with the fluid under pressure and further being in communication with the motor for sensing the fluid pressure and controlling the operation of the motor to maintain a selected fluid pressure, the pressure switch arrangement having means for affording fluid over-pressure protection thereto; a pressure sensor assembly, the pressure sensor assembly being in fluid communication with the fluid under pressure; a micro switch being selectively couplable to the pressure sensor assembly; and a set screw assembly being operably coupled to the micro switch for selectively positioning the micro switch relative to the pressure sensor assembly, wherein the micro switch is moveable with respect to the set screw assembly, a spring bias acting on the micro switch to maintain the micro switch in engagement with the set screw assembly.
