The Hypro D30GRGI is ready to connect to a small gas engine. This assembly includes the popular 9910-D30 diaphragm pump, a pressure regulator, and a 6:1 gearbox so that it can be coupled to a Honda 5.5 HP gas engine or similar (for example, Briggs).
Don't forget to purchase a valve and/or diaphragm repair kit if you intend to use this pump frequently for extended periods of time, or in a critical operation. When and if you have an emergency, you are prepared for it!
