does the pump heat, or does the motor. Big difference. If the motor heats it is working too hard, is not getting the proper voltage, or it isn't in a well ventilated space.
If the pump is overheating, it is experiencing extreme wear or isn't pumping enough water. Water going through the pump cools it. Perhaps the water supply is restricted, the discharge lines are too small, or the pump is working against too much head (elevation pressure).

I have to wonder why you need to do this in the first place. If you have the right type of pump, it should be able to run all day without overheating. Pumps generate heat, that’s normal. A ½-HP pump is like cramming four 100-Watt bulbs in that small space, it will get hot. Pump motors are fitted with an overheat protection switch that turns the pump off if it overheats. Pool pumps run all day and all night all summer long—all year long in many cases. Check with your pump dealer for a continuous-use pump, you may already own one and worry for nothing.
What is your budget?
The most flexible solution requires a PLC. The least expensive are at www.plcdirect.com.
If you are on a limited budget, you can cycle your pumps using a relay and a common household timer: Get a DPDT relay with a 120 VAC coil and contacts rated for your pump (240 VAC, ??A). Get a regular household timer, the kind you plug into a socket and that has permanent pins to set the on and off time, mine has a pin every ½ hour, so that I can turn something on for 30 minutes then off for 30 minutes all day long. Plug the timer to a new outlet that you will have connected to whatever triggers your pump. Connect a power cord from the coil of the relay into the outlet of the timer. The timer should now energise for 30 minutes and de-energise for 30 minutes. Connect one pump to one pole of the relay and the other pump to the other pole. You can adjust the timer to make the pumps cycle every hour or two or three…

Ive seen pumps set up this way by the use of two time clocks and two motor contacters. I dont think running the motor right off a timer is correct. Check with an electrician

There are alternating switch control systems
designed for this very purpose, (sump pump
controllers).
Don't try to re-invent the wheel here.
Your local 'Home Despot` should have
something that will 'do ya`.
If you do it with relays it's a bit too complex
to explain here. Some use a simple single
pole double throw switch or momentary contact
relay in the control circuit.

if they are working off of a pressure switch set one lower than the other,
