316 Stainless Steel Air-Powered Double Diaphragm Pumps for Chemicals, Fuel, and Flammable Liquids

With a 316 stainless steel housing and a PTFE diaphragm, these pumps resist a variety of acids, alkalies, and flammable liquids such as phosphoric acid, acetone, and methyl ethyl ketone (MEK). They're designed for moving large volumes of thick sludges and slurries in demanding environments. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All are submersible and can run dry.

Miniature Metering Diaphragm Pumps for Chemicals

With a footprint that's only a few inches in any direction, these diaphragm 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. Choose from pumps with either a 4-20mA or 1-5V DC input signal that controls the flow rate.

Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

Aluminum Air-Powered Double Diaphragm Pumps for Oil and Chemicals

A neoprene diaphragm resists oil and chemicals such as isopropyl alcohol and deionized water. These pumps have a rugged aluminum housing for moving large volumes of thick sludges and slurries in demanding environments. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All are submersible and can run dry.

Long-Life High-Accuracy Metering Diaphragm Pumps for Chemicals

A 316 stainless steel housing provides corrosion resistance for a long life in harsh environments. These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. They can run dry. Do not use with solids.

Pump Repair Kits—Repair kits include a pump head assembly, a diaphragm, valves, and seals.

Aluminum Long-Life Air-Powered Drum Pumps for Fuel

Pump fuel such as gasoline, kerosene, and diesel fuel. Also known as diaphragm pumps, these pumps have few moving parts that can fail for a long service life. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

Always bond and ground your application for static control. For more information about bonding and grounding, see Sections 1910.106 and 1910.107 of the Federal OSHA Code or see bonding and grounding equipment.

Pump Repair Kits—Repair kits include balls, O-rings, and diaphragms.
