Dosing tube pump in the automotive industry

24 HOUR DUTY PUMP FOR SEALANT DOSING The automatic and precise dosing of ink and sealant, 24 hours a day every day, is the role of a British made Verderflex® tube pump at an automotive industry supplier in South Africa. The process has a direct bearing on the quality of the finished product as the combination of the two substances is used to seal windscreens. It ensures there is no possibility of moisture ingress between the two layers of glass into which a tinted plastic laminate sheet is inserted. Any imbalance in the dosing would weaken the seal and result in the clarity of the windscreen being compromised. Verderflex® tube pumps are widely specified for a variety of applications in the automotive industry worldwide. In addition to pigment and glue dosing, they are used for coatings and acid transfer and to feed lapping solution. The proven capability of the Verderflex® auto control peristaltic pump therefore made it an obvious choice for Durban-based Reliable Electrical Services. Remote stop/start and speed control allowed it to be easily integrated into the automated windscreen sealing system. This model of Verderflex® tube pump with brushless dc motor, provides flow rates from 0.8 to 1312 ml/min at speeds from 10 to 250 rpm. Speed and flow rate are infinitely variable and the value of all adjustable parameters are indicated on a keypad with twin line alpha numeric display. Easy tube loading is a characteristic of this - and indeed all - Verderflex® cased peristaltic pumps. They are also stackable, self priming and can run dry. The pump at Reliable Electrical Services doses 64ml/min consistently at 40 rpm, around the clock. Eddie Horn, one of the founders of the company concludes, “The Verderflex® tube pump is ideal for this application. It gives us the assurance that precise ink/sealant combination will be applied to the windscreen.”
