Versatile, air-operated, hydraulic pump for heated or unheated paint spray systems and other fluid delivery applications. ■ Self-adjusting, stationary, hydraulic packing glands — need no maintenance throughout their life and cannot be overtightened or neglected. ■ Air-operated pump — can be used in hazardous locations with solventborne coatings. ■ Reciprocating plunger and stationary packing design — reduces pump wear and maintenance costs. ■ Wide selection of "standard" packing materials — for use with a variety of coating formulations. ■ Precision-ground, long-life hydraulic plunger — ensures long service life. ■ Large, stainless-steel ball checks — provide smooth fluid delivery with high-viscosity coating materials. ■ Large, enclosed solvent chamber — lubricates plunger and increases upper packing life. ■ Mechanical air valve — provides reliable, fast cycling action to minimize pressure fluctuations for a more uniform spray pattern. ■ Sheet metal cover — protects pump from the hazards of a normal industrial environment. ■ Positive-displacement, demand-type pump. Available in 15:1 and 30:1 fluid-to-air ratios. ■ For use in airless and air-assisted airless applications ■ Dual-acting, single-piston design. ■ Self-adjusting, stationary packings. ■ Circulating and non-circulating systems. ■ Wall, drum or dolly mounting. ■ Aluminum and stainless-steel models available. Typical Applications The versatile Model 64B pump is designed to operate multiple guns at mid-range volume or a single gun in high-volume applications of high-viscosity materials. Lower cycle rates of the 64B pump can easily accommodate abrasive coatings. The Model 64B pump is available in stainless-steel construction for corrosive materials.
