A Buna-N diaphragm stands up to lubricating oil such as hydraulic and motor oil. These pumps are designed to handle thick sludges and slurries.

These pumps have a PTFE diaphragm compatible with oil, fuel, and chemicals such as mineral spirits, methyl ethyl ketone (MEK), and xylene. They have a rugged aluminum housing for moving large volumes of thick sludges and slurries in demanding environments.

A neoprene diaphragm stands up to oil and chemicals such as isopropyl alcohol and deionized water. These pumps have large internal pathways and check valves with flaps to accommodate thick sewage, abrasive slurries, and industrial waste with large solids that would damage standard air-powered transfer pumps.

With a 316 stainless steel housing and a fluoroelastomer diaphragm, these pumps resist a variety of harsh acids and alkalies, such as phosphoric acid, nitric acid, and sulfuric acid. They have large internal pathways and check valves with flaps to accommodate thick sewage, abrasive slurries, and industrial waste with large solids that would damage standard air-powered transfer pumps.

Also known as sprayer pumps, these provide a smooth, uniform flow for agricultural spraying, soap dispensing, and chemical transferring.

A chemical- and impact-resistant PVDF housing stands up to aggressive chemicals such as methyl ethyl ketone and xylene.
