PUMP APPARATUS FOR SLURRY AND OTHER VISCOUS LIQUIDS

摘要

A peristaltic pump is operated by squeezing rollers pressing on an elastic tube supported inside a semicylindrical chamber. The collapsed tube is reopened by traveling side rollers which press the tube transversely. This expedites refilling and increases pump capacity. A surge chamber consisting of an elastic hollow cylinder housed inside a tubular housing provided with inwardly projecting annular ribs smooths out both minor and major surges in flow of the viscous material.
