Abstract: A pump having a pumping module and a motor module. The motor module has an electric motor and a first rotatable shaft driven by the electric motor. The pumping module has a pump housing with an internal pumping chamber, a drive shaft opening, and inlet and outlet ports in flow communication with the pumping chamber. The pumping module also comprises a pumping mechanism disposed within the pumping chamber driven by a second rotatable shaft extending through the drive shaft opening and coupled to the first rotatable shaft by a polymeric coupler.

Abstract: A beverage syrup pump system is disclosed including a pump housing having an internal pumping chamber, a pump motor, and a pumping mechanism driven by the motor within the pumping chamber. The pumping mechanism receives a syrup fluid at a first pressure and discharges the fluid at a second pressure which is greater than the first pressure. Connected to the pumping chamber is a cylindrical space with a spring and a plunger having a magnet. The plunger is in contact with a quantity of the fluid at a second pressure and moves along the cylindrical space against the biasing force of the spring. Once the second pressure exceeds a predetermined pressure, the corresponding fluid pressure in the cylindrical space exerts enough force on the plunger to move it past a predetermined point within the cylindrical space such that the magnet causes a reed switch in a first position switch to move to a second position and send a signal to a controller.

Abstract: A molded liner member for a fluid pump is disclosed. The liner member includes a generally annular ring, having an inner surface, an outer surface which is substantially concentric with the inner surface, and first and second end surfaces. The annular ring is molded from fiber reinforced polymer, and a majority of the fiber reinforcements in the polymer are oriented substantially parallel to an axis passing through the center of the annular ring. A method for making the liner member is also disclosed.
