Frequently Asked Questions
What does it do?
Coyotes protect pumps from running dry,
from overload, and from bad power. There is no plumbing and no
probes. They are built rugged for tough jobs.
On what kind of pumps does it work?
Submersibles, centrifugals, jets, and sumps
In what kinds of applications?
Water wells, oil wells, booster and lift
stations, chemical transfer, mine dewatering, sewage treatment,
solution mining, food processing, construction dewatering, and
cleanup of aquifers contaminated by hydrocarbons are the most common.
How does it work?
Coyote monitors the incoming power and the
electrical characteristics of the motor. When the pump quits
pumping fluid, those characteristics change, and the Coyote shuts it off.
What if there is not enough fluid to pump when the pump restarts?

Just push the RESET button or turn the
power off and then on again at the circuit breaker and the pump will restart.
Do I have to order a different Coyote for each size motor?
