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.

The fluoroelastomer diaphragm withstands higher temperatures than a neoprene diaphragm and has better resistance to fuel such as gasoline and kerosene. 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.

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.

Automatically control output from a distance using 4-20 mA or external-pulse signals. These pumps meter a consistent amount of liquid within ±2% of the maximum flow.

With a footprint that's only a few inches in any direction, these pumps fit into compact systems to dispense small amounts of acids, cleaning fluids, and other chemicals. They're often used in sterilization, photochemical, and water treatment systems.
