Corrosion-resistant chrome plating protects metal from the corrosive effects of water-based solutions. One size fits most standard 15, 30, and 55 gallon drums. Large 22 oz. output per stroke significantly reduces the number of times you pump, resulting in less hand fatigue. Broadly applicable pump is usable with a wide variety of solutions, including water-based solutions and solvents. Durable pump is ideal for thicker liquids, like motor oil. Do not use with corrosive chemicals. Teflon® coated packing seal increases chemical resistance.
