If you have an apex you simply use the WXM module to control any pumps..... same for buying the reeflink (if you don't have an apex). Now if you just want the pumps to communicate you just make sure to purchase the wireless ones and they will "sync" together, and the "master" pump will control the other pumps you have "slave pumps". This allows you to change flow such as say pump on the right is master, so while it is on, slave can be off... then pumps can reverse with slave on and master off.
Wireless in itself gives your aquarium GREAT random flow, however I feel adding the wxm (if you use apex controller) or reef link (if you don't have apex) allows you to actually change the vortech intensity and programs throughout the day, thus allowing you to do things such as rev up into a nutrient transport mode for water changes etc. But yes your pumps can be set to different program modes, and sync together wirelessly without any extra equipment. You just need one of the modules (Wxm or reef link) to change to different programs throughout the day as I believe with just wireless vortechs you pick a program and then the pumps will each run that program at different points in the day to give you that randomized flow.
Plenty of great pumps on the market, but I will stick with my vortechs for now as they offer amazing form and function while keep any power cords out of my tank. Combine that with easy battery backup and I'm sold
