1204/560 MP20/30 Control Unit

The 1204/560 MP20/30 Control Unit is a pump-mounted pressure regulator designed to attach to Comet MP20 and MP30 diaphragm pumps to maintain the pressure. This item comes with a 3/4-inch hose barb bypass and two 3/8-inch ball valve outlets. All diaphragm pumps need pressure regulators, and if you do not have a pump that includes one, then a regulator, such as this one, must be purchased separately.
