Pump

A pump comprising:

• a motor housing configured to support a motor;
• a pump head coupled to the motor housing, the pump head including
• an inlet configured to receive a fluid,
• an outlet in fluid communication with the inlet, and
• a bypass assembly configured to facilitate a path for fluid removal, the bypass assembly including
• a bypass vent, and
• a sealing member movable between a closed position where the sealing member blocks flow of the fluid from the inlet through the bypass vent and an open position where the inlet is fluidly connected to the bypass vent, and
• an impeller positioned within the pump head, the impeller operably coupled to the motor such that the impeller is configured to rotate to facilitate operation of the pump,
• wherein the bypass assembly is positioned downstream of the inlet and upstream of the impeller and the outlet.

• a bypass vent, and
• a sealing member movable between a closed position and an open position, wherein in response to the sealing member being in the closed position, the fluid from the inlet is restricted from flowing through the bypass vent, and wherein in response to the sealing member being in the open position, the fluid from the inlet is configured to flow through the bypass vent, and
• an impeller positioned within the pump head downstream the bypass assembly, the impeller operably coupled to the motor such that the impeller is configured to rotate to facilitate operation of the pump.
