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.

The Comet 1204.0560.00 Pressure Regulator will attach to the Comet MP20 and MP30 Diaphragm Pumps in order to regulate and maintain pressure. The pressure regulator also comes assembled on the Comet MP20GR and MP30GR versions as well. It is important to note that every diaphragm pump requires the use of a pressure regulator. If you don't order a version that includes a regulator, for instance the Comet MP20, then you will have to purchase the regulator separately.
