The 400 range of peristaltic pumps has been designed to offer the OEM a low cost means of dosing a wide range of liquids at high volumes (750 - 7500+ ml/min). As with all peristaltic pumps they have excellent suction performance with the ability to self-prime to 5 metres, even when priming from dry. Peristaltic pumps offer a good level of accuracy and repeatability and as only the tube contacts the pumped media, they are corrosion resistant, extremely reliable, easy to clean and inexpensive to maintain. The range of stock motors to fit the 400 series pump heads gives a good choice of performance and is adaptable to many existing installations. For volume applications a wide range of speeds, voltages and special mounting brackets are available. In addition to the intermittent duty DC or AC configurations the Williamson Manufacturing Company Ltd can now offer customers continuous duty industrial pumps with an induction motor (with a choice of 115v or 230v single-phase or 400v 3-phase induction motor and optional speed controller). For more demanding applications we have now developed an optional upgraded roller assembly for use on the 400 series pumps. Rollers rotate on long life industrial Bal Bearings and the rotor cage is manufactured from stainless steel. To upgrade to the BB roller assembly simply add the suffix ‘BB’ to the model number of the pump.
