Peristaltic hose pump

摘要

The pump has a roller wheel (1) comprising rollers (2) that are arranged on the wheel, where rotation axes (R) of the roller are arranged on a circle. A hose (3) comprises pump segments (4), which are passed around the wheel. The segments exhibit length that is adjusted in relation to a distance (A) of fixation points (P1, P2) to a roller wheel rotation axis (D) with a measure, in a released condition such that flow rate of fluid via the pump segments ranges to 0.01 per/minute, during standing of the roller wheel and impact of the points with fluid pressure in a range from 10 to 400 millibar.
