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.

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

Aluminum Air-Powered Transfer Pumps for Fuel and Flammable Liquids

UL listed for pumping petroleum products and rated for use with flammable liquids, these pumps move diesel fuel, gasoline, kerosene, and mineral spirits. They can be grounded to dissipate static electricity. All have a pressure-relief valve set at 50 psi per UL 79 safety standard. 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 Oil, Chemicals, and Large Solids

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. 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.

Match your pump’s intake and dischange connections to select the right kit.

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.
