Graco pumps that are specifically designed for oil
Graco’s Carbon Steel Fire-Ball 5-1 ratio pump has been providing excellent service for many years for thousands of pumping duties including heavy duty applications. The Firebail Pumps are designed for both oil and grease, is available as an drum length pump for 205 Litre Closed top drums, also a stubby pump version.
The Carbon Steel President range of pumps are one size bigger than the Firebail. There are 3 different versions: 3-1, 6-1 or 10-1 ratio. President pumps are intended for high volume oil transfer applications. Model numbers e.g 204254 or 203876
Double Diaphragm pumps that are used for oil
Graco’s range of Aluminium Double Diaphragm pumps contains a variety of internal wetted parts that are suitable for oil: Acetal, Hytrel, Buna-N and Geolast are all good for oil products. Sizes of pumps range from 3/4″ to 3″.
A Double Diaphragm pump is a 1-1 ratio transfer pump and is not designed to overcome high delivery heads and viscous oil products. In these circumstances, a piston pump is usually a better bet.
Other piston pumps that can be used for oil
Many oil products are harmless in their effect on generally available Graco pump constructions. We are often able to supply alternative pumps in circumstances where our dedicated oil pumps do not match flow and pressure requirements..
