What part of the circuit do you have done? Please post what you have, or explain how you think this problem can be solved. Have you done anything similar to this before?

I have reverse-engineered your problem and used a PLC program to simulate a relay circuit (using only relays and 3 timers). It can be done in 14 rungs, but gets a little messy for a relay circuit (23 relays needed). The timers may not be needed, depending on how you are going to determine that a pump has failed.
