Binks Bare MX1231 Series Air Assist Airless Piston Pumps
Air Assisted Airless 31:1 Piston Bare Pump
Manufacturer: Binks
Part #'s: MX1231XX
Description: MX1231: 1.2 gal/m output and 31:1 ratio bare pump
Binks MX Pumps are a completely new design in air-operated pump technology utilizing patented magnetic detents to provide fast changeover with virtually no pulsation. The result is paint delivery with less pulsation for a more consistent finish. The MX pistons are ceramic coated – the most durable surface available – for resisting wear from abrasive materials.
The MX Pumps are ideal for air assisted airless spray finishing, supporting 1 to 2 spray guns, with thin to medium viscosity coatings.
