Fluid pump for groundwater wells with cycle counter

A cycle counter apparatus for use with an air-driven fluid pump, the apparatus comprising:

• a main housing having an inlet, an outlet and a bore extending between the inlet and the outlet, the inlet and the bore both being in communication with a pressurized fluid signal being applied to remove a liquid from a wellbore filling with the liquid;
• a magnet housing moveable linearly within the bore of the main housing from a first position to a second position in response to the pressurized fluid signal entering the bore;
• a magnet secured to the magnet housing;
• a switch housing releasably secured to the main housing generally parallel to the main housing;
• first and second longitudinally spaced apart sensing components disposed within the switch housing for detecting movement of the magnet in response to the pressurized fluid signal, and wherein detection of the movement of the magnet provides an indication of cycling of the air driven fluid pump;
• and
• a biasing element disposed within the bore of the main housing and providing a biasing force to bias the magnet housing toward into the first position when no pressurized fluid signal is being received in the bore.

• a magnet housing moveable linearly within the bore of the main housing from a first position to a second position in response to the pressurized fluid signal entering the bore;
• a magnet positioned within the magnet housing;
• a stroke limiter secured to the outlet of the main housing for limiting linearly movement of the magnet housing, while allowing the pressurized fluid to exit the outlet of the main housing;
• a switch housing releasably secured to the main housing generally parallel to the main housing, the switch housing including a plurality of circumferential arms to enable attachment and removal of the switch housing;
• first and second longitudinally spaced apart sensing components disposed within the switch housing for detecting movement of the magnet in response to the pressurized fluid signal, and wherein detection of the movement of the magnet provides an indication of cycling of the air driven fluid pump;
