Aro/ingersoll-rand 66605J-3EB Diaphragm Pump 13 Gpm

Product Description

The ARO/INGERSOLL-RAND 66605J-3EB is a non-metallic air operated diaphragm pump designed for fluid transfer in demanding industrial, chemical, and process applications. The pump body, housing, check seats, and ball components are constructed from polypropylene, while the diaphragm and ball seats are made from Santoprene for chemical compatibility and flex durability. Connections are 0.5 inches NPT on both the inlet and outlet, with a 0.25 inches NPT air inlet. Maximum flow rate is 13.0 GPM with a maximum working pressure of 100 psi. The unit weighs 7.2 pounds, making it a compact, portable option for a wide range of fluid handling tasks. Installation is performed by trained industrial mechanics, plumbers, or fluid handling technicians.

This pump is suited for low-flow chemical transfer, wastewater handling, and general fluid movement in residential, commercial, and light industrial settings where metallic contact with process fluids must be avoided. The all-polypropylene wetted body construction makes it a common choice for mildly corrosive liquids, slurries, and fluids containing small solids up to 3/32 inches in diameter. Its air-powered operation eliminates the need for electrical connections at the pump head, which is valuable in wet or hazardous environments. A single-port design simplifies installation in tight plumbing configurations.

Key Features

• Non-metallic polypropylene body, housing, check seats, and ball material for corrosion resistance

• Compact build at 7.2 pounds for easy field installation and repositioning

Compatibility

Designed as an OEM-style air operated diaphragm pump replacement for non-metallic 0.5 inches NPT pump applications requiring polypropylene wetted parts and Santoprene diaphragm construction.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or fluid handling technician familiar with air-powered pump systems. Shut off and bleed down the compressed air supply before making or breaking any connections. Ensure all NPT threaded connections are sealed with an appropriate thread sealant rated for the process fluid. Verify that the air supply pressure and flow are within the rated operating limits before startup.
