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.

Plastic Air-Powered Transfer Pumps for Oil
A Buna-N diaphragm stands up to lubricating oil such as motor oil. These pumps are designed to handle thick sludges and slurries. 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. All are submersible and 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 Fuel, Oil, and Large Solids
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. 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.
Air-motor maintenance kits include seals, O-rings, gaskets, retaining rings, and an air valve spool.
