Rebuild your Comet MP20 & MP30 Diaphragm Pump with the Comet 1204.0674 Regulator
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 MP20-GR and MP30-GR 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-GR, then you will have to purchase the regulator separately.
