| Peristaltic Pumps |
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.
