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. The controller will immediately stop the pump motor if it receives the signal from the reed switch, or if a timer sends a signal indicating the pump has been running for a predetermined maximum run time.
