Engineering:Water well pump

A water well pump is a pump that is used in extracting water from a water well. They include different kinds of pumps, most of them submersible pumps:

• Hand pump, manually operated
• Injector, a jet-driven pump
• Mechanical or rotary lobe pump requiring mechanical parts to pump water
• Solar-powered water pump
• Pump driven by air as used by the Amish
• Pump driven by air as used in the Australian outback
• Manual pumpless or hand pump wells requiring a human operator

The pump replaces the use of a bucket and pulley system to extract water.
