Hand Pumps for Wells

Original post by (Jonesie) at FluTrackers:
Because the power is expected to go out for months at a time during a pandemic, the farmers in my area with existing water wells are installing hand pumps to water their livestock and supply their personal use.
Hand pumps are available for deep wells going down as far as 300'.
The equipment for shallow wells is less costly.
Compare prices, they do vary considerably for the same equipment.
Pumping Basics for Deep Wells
NOTE: Type of pump head may differ from the picture on left but installation requirements are the same.
If water is less than 300 ft down: You need four basic components to raise water from these depths.
1) The pump-head is the part you see above ground and provides the pumping action. Ours work on any well (dug or drilled). Some can be used with windmills.
2) The cylinder is the heart of the system. It contains the valves and leathers or seals that provide the lift. Place in well below water level. Most work best with a foot valve. The cylinder you choose must fit into your well casing.
3) The drop pipe extends from the pump to the cylinder. We recommend galvanized steel or PVC (Plastic). (Steel is the traditional favorite, but plastic is less expensive, much lighter and will never rust.)
4) The pump rod runs from the pump to the cylinder inside the drop pipe. It provides the linkage that transfers the pumping action from pump-head to cylinder.
All our deep well components are USA made to the highest standards.
For pumping from 9'-300' use our Stainless Pump Head w/Cylinder Set, or for pumping from 0'-100' you can use our "Good†Deep Well Pump Head w/Cylinder set, or our stainless steel unit with the 1-12" cylinder.
If your well is much deeper than 300', (to 600') then a solar pump may be useful
THERE ARE HAND PUMPS FOR EXISTING WELLS WITH ELECTRIC PUMPS. BOTH ARE INSTALLED SIDE BY SIDE AND WILL WORK INDEPENDANTLY OF EACH OTHER.
Again, there are a lot of companies supplying pumps and drilling wells, so look around to find the one that best suits your needs.
If you are thinking of drilling a new well, Montana's website has a lot of useful information:

On the farm I once owned we had 2 water wells. One was a 90' shallow well with a hand pump. The water was the greatest. We carried it into the house every day for drinking and cooking. The other was installed for the livestock. It was a much deeper well, 250', had an electric pump, and was very hard mineral water. We piped it into the house for laundry and bathing.
