Double-action piston pump
Self priming
Delivers on the forward and the back stroke
Less than five cycles yields a gallon (3.8 Liter) 26, 27, 28 Series pumps are:
Made in the same style
Have the same action
Differ in their materials of construction
Are constructed using specific polymers and elastomer for resistance to certain types of chemicals For use with:
Chemically compatible liquids up to 80° F (26° C)
Viscosity not exceeding 2,000 SSU (about as thick as 40 weight motor oil at room temperature). Handle effort increases as viscosity approaches this maximum.
27 Series and Model 26 are generally useful with compatible liquids in a mild acidity/alkalinity range of pH 4-9. Avoid stronger acids and caustics.
28 Series are useful in a wider pH range.
Many other chemical characteristics effect choice of pumps
