Kremlin Rexson 112G 04-220FT Flowmax 4:1 Pneumatic Paint Pump 8.8L/min 348psi

The Kremlin Rexson 112G 04-220FT is a heavy-duty Flowmax® pneumatic paint pump designed for high-volume, low-pressure circulation and supply of solvent-based and waterborne coatings. It uses a sealed Flowmax bellows system to isolate the fluid from the air motor, making it ideal for moisture-sensitive or reactive coatings like 2K polyurethanes.

This model features a 4:1 pressure ratio, hardened stainless steel wetted parts, and delivers up to 2.33 GPM (8.8 L/min) at 20 cycles per minute. Designed for long-life operation with minimal maintenance, it is suited for demanding industrial and finishing applications.

Unit is new surplus, unused, and in excellent condition. Wall mount configuration.
