The 400i series peristaltic pumps has been designed to offer the user a quiet, rugged and reliable means of dosing a wide range of liquids at up to 10 Litres per minute. The 400i series peristaltic pumps have excellent suction performance, even priming from dry. Peristaltic pumps offer a good level of accuracy and repeatability and as only the tube contacts the pump media, they are corrosion resistant, easy to clean and inexpensive to maintain. The 400i has a simple lift off cover to facilitate easy tube change and is available with a choice of tube size & materials.
Williamson pumps also offers an optional, extra cost, larger internal diameter smooth bore stainless steel spigot for use with the 400i series pumps which further enhances flow rates and offers an alternative spigot material where the existing material is un-suitable. The O.D of the external spigot suits 19mm ID tube. Smooth bore spigots can give a significant increase in flow in comparison to flow rates for the standard spigots.
