ABSTRACT

Nonclog pumps, as defined by the Hydraulic Institute (ANSI/HI Standard 1.3, 2000), are “pumps designed to assure maximum freedom from clogging when handling liquids containing solids or stringy material.” These pumps are also commonly known as solids handling or sewage pumps. The category of nonclog pumps encompasses a broad range of pump sizes and designs representing one of the largest market segments available. This paper focuses on centrifugal nonclog pumps 3 bhp and greater with a discharge diameter larger than 3 inch. The available types, operation, design elements, materials, driver configuration, and variable speed operation are presented herein. Typical field problems with their resolution, vibration analysis, and equipment upgrades are also discussed.
