Well pump or water pump protection switches & controls:
What can we install to protect a water pump from damage if the well runs out of water? How do we protect the well pump from damage due to pump short on-off cycling? How can we protect the well pump and its circuit from electrical overloads or lightning damage?
This article describes all of the devices to protect water pumps from damage from continuous running, short cycling, overloading, no well water, low yield wells, power surges, or lightning strikes.

Watch out: A water pump or "well pump" can be damaged by conditions that cause the pump to run continuously, particularly if the pump is running "dry" - without water passing through its mechanical parts. The result can be the need for a costly repair or for pump and control replacements.

Worse, a more powerful pump, especially a submersible pump that fails to turn off when it should may also pump water at high enough pressure to burst pipes, flood a building, or injure a bystander - dangers we discuss separately
Well pumps can also be damaged by other conditions such as low voltage, lightning strikes, entry of debris in the well water, or corrosive water.
Generally when readers ask what to do about a pump that won't shut off we suggest that they take the following steps
Reader Questions: Water Pump Won't Stop Running - can I install an automatic shut-off

My pump keeps running and wont shot off, I have good water pressure.

I live in the North (Nunavut) and our water is supplied by truck and held in a 700 gal. tank. Sometimes when it storms and the trucks fall behind schedule and we run out of water. The problem is when this happens the pump continues to run and if we don't catch it quickly it heats up and ruins the impeller centre or the bearing. My question: is there a shut off I can install on the pump or water line that will shut the pump off when the tank is empty.
Reply: yes. here is a list of the types of well protection devices available along with where-to-buy information
If your water pump keeps on running and won't shut off,
1. TURN IT OFF manually so you don't burn up the pump motor.
2. Then diagnose the trouble, starting at
Yes there are more sophisticated water pump controls with sensors that can shut off the pump it it's pumping air. Typically these work by monitoring the current draw of the pump, the pump motor temperature, or actual water flow.
There are also water pick-up "tailpiece" fittings intended for use in a well that might work in your tank that will recycle water through a pump to prevent its burn-up when water runs too low at the source.

Frequently Asked Questions (FAQs)
Question: our pump control trips off and we have to re-set it using the lever on the control

From what you describe most likely the control is working properly, protecting the pump from damage by shutting the system down when your well is running out of water - when the demand exceeds the well flow rate. When you wait a time for well to recover the pump is then OK. Some pump pressure control switches require manual reset.
More explanation is in the article above.
Question: new well pump burned up after 15 months

This question was originally posted in the CHECK VALVES, WATER SUPPLY
If your installer can show you a clogged check valve s/he'd be on reasonable ground, as if a pump can't push water into the pressure tank to satisfy the pressure control switch it'd keep running and risk burnout.
A check valve installed backwards or one that is stuck shut can also burn up a pump.
Flow reducers have a different purpose: to slow the flow rate out of the well in an effort to avoid burning up a pump in a well that has a slow recovery or flow rate into the well bore. The presence of that device on your system makes me suspect that the root problem is poor well flow rate; if the pump gets ahead of the flow rate into the well bore it can indeed burn up unless it's protected.
