This is a very good pump for more aggressive liquids. The combination of the ryton body and stainless steel intake and discharge tube material make this an excellent choice for a variety of tougher liquids and chemicals such as esters, ketones, alcohols and hydrocarbons. This is a self priming pump that can deliver up to 6 gpm. This has good capabilities for the money as well as being built for industrial use. We have very good rotary pumps that will last a long time.
