Ingersoll Rand 666100-362-C 1" Pro Series Air-Operated Double Diaphragm Pump, Aluminum, Nitrile, 35 GPM

The Ingersoll Rand (ARO) 666100-362-C is a 1-inch Pro Series air-operated double diaphragm (AODD) pump designed for reliable, efficient fluid transfer in demanding industrial environments. Built with an aluminum center body, aluminum fluid caps, and a single-piece manifold, this pump delivers up to 35 GPM (133 LPM) at a maximum operating pressure of 120 PSI (8.3 Bar).

The pump features ARO's patented "unbalanced" air valve design, which prevents stall-out even under low air inlet pressures, ensuring consistent and uninterrupted operation. Bolted fastener construction provides leak-tight integrity for environmentally responsible fluid handling. Pre-assembled components make installation straightforward and reduce setup errors.

Key Features:

• 1" NPTF Inlet/Outlet — 1-11/2 NPTF-1 connection for easy integration into existing piping systems
• Aluminum Construction — Lightweight yet durable aluminum center body, fluid caps, and manifold with stainless steel hardware
• Nitrile Diaphragm — Offers broad chemical compatibility; suitable for motor oil, gear oil, transmission fluid, and waste oil
• Acetal Ball Checks / Polypropylene Seats — Reliable check valve performance across a range of fluids
• 35 GPM Maximum Flow Rate — High-volume transfer capability for industrial, maintenance, and lubrication applications
• 120 PSI Max Operating Pressure — Handles demanding pressure requirements
• 1/4"-18 NPTF Air Inlet — Standard female air connection, 1:1 pump ratio
• Suspended Solids Handling — Capable of handling solids up to 0.125 in. diameter (slurries and high-viscosity fluids)
• 70 dBA Sound Level — Relatively quiet operation for a pneumatic diaphragm pump
• No-Stall Operation — ARO's patented unbalanced air valve ensures continuous performance at low air pressures
• Easy Serviceability — Quick access to ball checks and fluid caps for maintenance and repairs
• Agency Compliance: ATEX, CE, RoHS, REACH

Compatible accessories include the 66073-2 Air Line Connection Kit, P39224-614 Filter/Regulator, 66100 Wall Mount, 66975 Cycle Counter Kit, 637118-C Air Section Service Kit, and 637119-62-C Fluid Section Service Kit. This pump is not recommended for closed-system oil applications (where the pump remains pressurized when not in use) without the thermal relief kit PR-100.
