The SLH Twin Screw Pump is engineered to provide gentle handling of viscous products and media with larger soft particulates. It’s robust design provides exceptional durability, quiet operation and virtually pulsation-free pumping. The SLH standard offering includes many additional features that make this pump the best value in the industry today. Replacement parts are in stock and attractively priced.

The SLH is a dual duty pump that can be applied for both process and CIP requirements.
