Grit Pump

Grit is highly abrasive. For wastewater treatment plants, grit is typically defined as an `inorganic solid” and it can be made up of sand, grav­el, cinder, glass and other heavy inorganic material. The major abrading component of grit is silica sand. The amount of grit entering these plants varies. However, both facilities must re­move it as soon as possible to alleviate erosive wear as the process water moves through the plant for treatment. Grit removal systems are provided in many different forms, and all require pumps for disposal of the inorganic solids. Historically the design choice for grit removal has been the recessed impeller, vortex centrifugal pump or hardened materials for a self-primer pump. These designs have been used in grit/slurry applications for more than 30 years and are industry proven.
