A slurry is defined as a suspension of solids in a liquid. Typically the liquid is water and the solids can be anything from soft materials such as sewage and food processing waste (potato skins, fish parts) to abrasive solids like sand, fly ash and coal. Mitchell Lewis & Staver Co. offers pumps to handle either a “soft” or “hard” slurry. Keep in mind a typical centrifugal pump really can’t handle more than 3% - 5% solids by weight. Specialty pump manufacturers like Toyo, Yamada and Liberty Process can handle higher solids concentrations.
