Comfort Pro is an advanced pump kit, including a big double diaphragm pump, designed to create a balanced ink flow. The pump runs automatically at two present pump speeds; one at a slow pace for normal supply and return, and one at a quick pace for evacuation. The pump system has a unique reversing valve for quick evacuation of the chamber.

Comfort Pro is a complete air operated, balanced flow pumping system, where one-half of the pump supplies ink to the chamber, and the other half returns the overflow of ink from the chamber back to the ink bucket simultaneously, with one dual pump only.
