S Davis

I am looking for a variable speed pump with a pressure control, anyone know of one?
I have heard grundfoss makes one but can't find anything about it.

Grundfos makes a UP 15 VS model

that can be used with any 0 - 10 vdc or 4 - 20 ma signal input. You can use any pressure control or differential pressure sensor that produces this type of signal.

I'm on vacation for hte next 10 days, but you can contact Tony Radcliff @ tradcliff@us.grundfos.com and he can provide you specific application assistance.

The I & O for this product can be obtained at the following address: http://www.us.grundfos.com/web/download.nsf/Pages/DnldByProductLine?OpenDocument&Start=1&Count=80&Expand=5.1&RestrictToCategory=HVAC#5.1&RestrictToCategory=HVAC5.1&RestrictToCategory=HVAC
