New Pump Features Bellows Seal Design


Graco's Orion piston pumps and spray packages feature a bellows seal design that replaces the throat packings and throat seal lubricant in traditional piston pumps, virtually eliminating the possibility of air or moisture contaminating the fluid. The all-stainless steel design and co-polymer polypropylene bellows construction offers reliable performance for shear- and moisture-sensitive coatings.

Other features include a simple air motor design with a minimal number of parts, precision air motor control for excellent control at low input pressures for fine-finish applications, a large valve ball that provide virtually no pulsation and easy
flushing, and new style packings for long life and easy cleaning.

Two Orion models are available with 15:1 and 28:1 pump ratios, and maximum fluid outlet pressures of 1740 psi and 3248 psi, respectively. Bare pumps, wall-mount and cart mount packages are available with airless or air-assisted spray guns.
