Apocalypse Well Pumps refuses to offer a one-size-fits-all solution, so we offer three different pump models for shallow (AK), medium (AR), and deep (SJ) wells. There are two solid reasons for this:
First, one has to trade volume for height, this is a mathematical necessity. Our shallow pumps can move a lot of water (5-6gpm) because of a short lift, but as depth increases, a smaller piston is needed to reduce the effort. A smaller piston delivers less water (E.G. 100ft=3.5 gpm, 200ft 1.5 gpm).
Second, deep wells are often constructed differently than shallow wells. Deeper wells often transition to a 4” casing. This makes for a tight fit, a pump that is long and narrow is the only solution. Our SJ deep pumps are designed for this.
The best pump model for static water levels are listed below. Click on the pump model to see description and to order.
For most wells with a submersible pump drilled after 1990, in a casing 6" or larger, this chart works for selecting the correct pump. If your well is different then click on "Weird Wells" tab.
