wireless controll of pumps, run plus off

[still learning]

i have a dillema .
cannot get any signal cabling to two sets of pumps i only have limited information on what is exactly required .
but guess it requires one pump to know the other is running or stopped . and visa / versa.
does anyone know any available products .
the signal would opperate a relay to close the contacts to run the pump.
sorry its a bit vauge.
just trying to get some information while others are busy . cheers all .

Don't the pumps require power to them in order to run???

In which case why would the control box have to be anywhere near to the pumps? Cabling is all that is needed and then you can put the actual controls as far away as you like (providing you size the cables correctly)

Isolate leg of pipework, weld a stabbing on the pipe and fit a flow switch(paddle type)
