Abstract
A pumping apparatus for pumping a liquid from a source to a target including a motor and pump driven by the motor. Sacrificial zinc components are utilized to minimize corrosion due to chlorine vapors. Measures to ensure that liquid is pumped in only one direction include the use of a full wave rectifier and/or a spacer incorporated with a swivel platform to limits the range of the angle between the motor shaft and the pump piston. To minimize the risk of rupturing the pump, the pump piston includes a relieved portion in fluid communication with a transverse bore of the pump housing when the piston is axially inserted within the pump housing in its full forward position. To prevent overheating and damage to the pump components, the pumping apparatus makes use of a positive temperature coefficient (PTC) resistor interposed between the motor and a current source.
