Abstract

See full text

A peristaltic pump squeezes a hose between squeezing rollers and a counter bearing to move fluid through the hose. To compensate for production tolerances and non-uniformities in hose thickness, and to also keep the mechanical loading of the hose as low as possible during the operation of the pump, the spacing between the squeezing rollers and the active surface of the counter bearing can be varied. The counter bearing has a conical or cone-shaped adjusting surface which is supported against a complementarily shaped support surface on the pump housing. The spacing between the squeezing elements and the active surface of the counter bearing can be adjusted by moving the counter bearing relative to the support surface.
