Schlauchpumpe

The pump has a holder (2) for a large number of rollers (22) acting against the hose, while a motor (1) consists of a driving body (11,12) and a shaft (13) driving the holder. A pressure unit (3) secures the hose in place at the rollers. The body extends at least partly inside the holder, and a bearing (5) can be mounted between them, being typically fixed to the holder. The body can have a driving sleeve (12) at the end towards the holder, a bearing for the shaft being housed inside the sleeve. This bearing can be offset in the axial direction (6) from the first one (5). The pressure unit can be formed by a flap (31,32), and this and the rollers can be arranged to act simultaneously against several parallel hoses. ADVANTAGE - Simple to miniaturise, and requires little maintenance or motor power.
