This medium-pressure diaphragm pump by Hypro is suitable for pumping a variety of fluids such as herbicides/pesticides, liquid fertilizers, and more. The Hypro D403 can be powered by a gas engine, or PTO shaft (with PTO adapter). This is the pump commonly found on Lesco (now John Deere) sprayers.
Important: You cannot use a diaphragm pump without a regulator.
Also, 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!
