These types of solids are commonly found in waste water treatment plants and other sever duty installations.
ESSCO offers a prorated 5 YEAR WEAR WARRANTY as an option. Consult factory for details.
VOLUTE: Each ESSCO back pullout style volute is designed for ease of assembly and maximum life and is manufactured from extremely abrasion resistant materials. Extra material is provided in high wear areas as well as special designs to handle heavy grit slurries and sludges. Due to the Brinnell hardness of the volute all bolting flanges are slotted to allow for ease of assembly. ESSCO has a standard centerline discharge volute which allows it to be self venting and automatically releases air trapped in the pump volute (also known as an air bound pump). Air bound pumps are a common complaint of users who have tangential discharge volutes. The centerline discharge also eliminates the need for a right hand and left hand pump case. An optional conventional tangential design is available upon request.
SUCTION COVER: A contoured suction cover is provided to insure passage of suction sized solids from grit, rags or sludge laden liquids. The suction cover thickness ranges from .75” at the volute bolt flange to a massive 1.25” thickness at the point of highest wear.
