Our competitors often use piston pumps. They are more complicated and difficult to maintain than our gear pump. Piston pumps have more wear parts, need periodic rebuilding, need a constant supply of oil to maintain their seal, and the output pressure fluctuates as the piston goes up and down. Our hardened gear pump requires no oil, does not wear, and supplies a smooth, constant flow of adhesive to your process. Since the pump is mounted on top of the follower plate, it can be replaced in about 20 minutes.
