The 300 series range of peristaltic pumps has been designed to offer the OEM a low cost means of dosing a wide range of liquids at higher volumes (50-160ml/min) than the mini & micro pumps. As with all peristaltic pumps they have excellent suction performance, are self priming up to 5 metres from dry and capable of pumping up to 10m head pressure. Peristaltic pumps offer a good level of accuracy and repeatability and as only the tube contacts the pumped media, they are corrosion resistant, easy to clean, extremely reliable and inexpensive to maintain. Additionally the 300 series of pumps offer extremely long tube life because of their low friction needle bearing rollers and unique tube cantering roller cage. Coupled to this the motor gearboxes are built with ball bearings throughout which also offers exceptional longevity. A special chemical resistant version (PP after part no) is also available that uses polypropylene tube fittings.
