PTFE Air-Powered Transfer Pumps for Harsh Chemicals

With all PTFE wetted parts, these pumps offer the best chemical resistance of all our air-powered transfer pumps and can handle solvents and petroleum-based fluids that PVDF pumps can’t. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. All can run dry.

Fluid-side maintenance kits include diaphragms, check valve balls, and seals.

Air-motor maintenance kits include seals, O-rings, gaskets, retaining rings, and an air valve spool.

Aluminum Air-Powered Transfer Pumps for Water and Chemicals

The Santoprene diaphragm resists cracking for a long service life and stands up to water and chemicals such as ammonium hydroxide. These pumps have a rugged aluminum housing for moving large volumes of thick sludges and slurries in demanding environments. All are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Pumps are submersible and can run dry.

Fluid-side maintenance kits include diaphragms, check valve balls, and seals.

Compact Air-Powered Transfer Pumps

Small enough to fit in the palm of your hand, these pumps transfer water, detergents, and chemicals. They have a chemical-resistant polypropylene housing. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Pumps can run dry.

Pumps with fluoroelastomer diaphragm are also suitable for use with fuel and oil.

Smooth-Flow Air-Powered Transfer Pumps

Also known as sprayer pumps, these provide a smooth, uniform flow for agricultural spraying, soap dispensing, and chemical transferring. They automatically turn on when you open the outlet valve. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber. Do not run dry.

Santoprene diaphragm stands up to ammonia and resists cracking for a long service life.

Continuous-Duty Any-Direction Constant-Flow-Rate Pumps for Water and Coolants

Rated for continuous use, this pump is often used to move caustics such as antifreeze and salt water. Mount it in any position, even upside down. Also known as a diaphragm pump, it is typically used for low-flow spraying, draining, and washdown applications. Pump has a pressure switch that automatically shuts off the pump at the maximum pressure. It is self-priming, which means it creates a suction force to draw liquid upward. Pump can run dry and does not require an initial fill, so it’s a good choice for applications without a constant flow of liquid. Do not use with solids.

Polypropylene Extended-Life Air-Powered Drum Pumps for Chemicals

The polypropylene housing provides good resistance to caustics such as ammonia, electropolishing solutions, and detergents and cleaning fluids. Also known as diaphragm pumps, they have few moving parts that can fail for a long service life.

Choose a pump with a PTFE diaphragm for superior resistance to a wider variety of concentrated chemicals than Santoprene. Install an air line filter/lubricator to ensure efficiency and reduce wear on the pump.

Repair kits include components such as O-rings, valves, balls, and diaphragms.

PVDF Extended-Life Air-Powered Drum Pumps for Chemicals

A chemical- and impact-resistant PVDF housing stands up to aggressive chemicals such as methyl ethyl ketone (MEK) and xylene. Also known as diaphragm pumps, they 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.

Repair kits include O-rings, valves, and diaphragms.

Miniature Metering Pumps for Chemicals

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. 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.
