Peristaltic pump Blackmer

The Abaque pump operates on the peristaltic principle which was patented in 1925 by Mr. Horthaus of France. It is classified as positive displacement pump meaning that a fixed and known amount of fluid is discharged per revolution of the pump with flow independent of discharge head. The pump operates by compressing a specially designed elastomeric hose between a set of two or more shoes attached to a rotor and the internal wall of the pump case or housing. Fluid in the hose is forced from the inlet side of the pump toward the discharge by the squeezing or compressing motion of the shoes on the rotor of the pump as it rotates. This peristaltic action is in some ways similar in nature to that of the human digestive tract.
