Pump system with leak damage protection

An electric diaphragm pump comprising:

• a pump housing comprising a first housing and a second housing;
• a pump head assembly in the first housing;
• a motor assembly in the second housing;
• a fluid sensor;
• and
• a leak alert system and/or pump shut-off control system,
• wherein the first housing is coupled to the second housing,
• wherein said pump head assembly includes a seal comprising a diaphragm between a pump chamber and a diaphragm drive chamber, the pump chamber and diaphragm drive chamber at least partially defined in the pump head assembly,
• wherein the seal is configured to prevent fluid from leaking out of the pump chamber,
• wherein the fluid sensor is configured to detect a presence of fluid which has leaked outside of the pump chamber,
• wherein the fluid sensor is located in the diaphragm drive chamber and outside of the second housing,
• wherein said fluid sensor comprises a first probe, a second probe supported on a curved surface of a base, the base having the curved surface to integrate with the pump housing,
• wherein said first probe and said second probe are spaced apart by an air gap,
• wherein the presence of fluid across the air gap creates a conductive path between the first probe and the second probe,
• wherein said first probe and said second probe are components of a circuit which activates said leak alert system and/or said shut-off control system, and
• wherein the leak alert system is configured to indicate that fluid has been detected by the fluid sensor and wherein the shut-off control system is configured to stop operation of the pump based on fluid being detected by the fluid sensor.

An electric diaphragm pump comprising:

• a pump housing comprising a first housing and a second housing which is coupled to the first housing;
• a pump head assembly in the first housing;
• a motor assembly in the second housing;
• a fluid sensor;
• and
• a leak alert system and a pump shut-off control system,
• a third housing coupled to said pump housing, said third housing comprising circuitry for said leak alert system and said leak shut-off control system, said leak alert system and said leak shut-off control system being in communication with the fluid sensor,
• wherein said pump head assembly includes a seal comprising a diaphragm directly between a pump chamber and a diaphragm drive chamber at least partially defined in the pump head assembly,
• wherein the diaphragm drive chamber includes diaphragm drive components configured to drive a pumping motion of the diaphragm, such that fluid may be pumped through the pump chamber via said pumping motion, said diaphragm drive components including a wobble plate in driving engagement with a diaphragm pumping member via an output shaft of the motor assembly and wherein said pumping member includes one or more pistons which are integral with the diaphragm,
• wherein the seal is configured to prevent said fluid from leaking out of the pump chamber,
• wherein the fluid sensor is configured to detect a presence of fluid which has leaked outside of the pump chamber before the fluid enters the second housing,
• wherein the fluid sensor is located in a cavity of the diaphragm drive chamber and outside of the second housing,
• wherein said fluid sensor comprises a first probe and a second probe,
• wherein said first probe and said second probe are spaced apart by an air gap,
• wherein the presence of fluid across the air gap creates a conductive path between the first probe and the second probe,
• wherein said first probe and said second probe are components of a circuit which activates said leak alert system and said shut-off control system, and
• wherein the leak alert system is configured to indicate that fluid has been detected by the fluid sensor and wherein the shut-off control system is configured to stop operation of the pump based on fluid being detected by the fluid sensor.
