Re: Epics and IPFCs used for controlling the speed of the pump. I noticed that the pricing for Epics mounted and IPFC's mounted is significantly lower than for the unmounted versions. Is there a reason for this? Why would that be the case? A: Mounting an EPIC or an IPFC is convenient and fast onto the Foras pumps. More work is required to have it separately mounted, which is reflected in the pricing.
