On and off timer to control a pump

[leehawa]

I am looking to switch on a Grunfos pump on a megaflow hot water tank with a wireless Rf switch
I am looking for a timer which when it receives a signal just comes on for 30 seconds to a minute and then shuts off
I am not looking for a 7 day programable timer just one that will come on when ever I press a switch and then shut off after a specfied time.
This on off process can can occur as manytimes in a day as required.
