A Verderflex tube pump is enabling Durban-based automotive industry supplier Reliable Electrical Services to ensure the automatic and precise dosing of ink and sealant 24 hours a day, every day.

The dosing process has a direct bearing on the quality of the finished part, 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 auto-control peristaltic pumps are said to be particularly suitable for applications in the automotive industry. In addition to pigment and glue dosing, they are used for coatings and acid transfer and to feed lapping solution.

To this end, Reliable Electrical Services decided to use a Verderflex tube pump with a brushless DC motor that provides flow rates from 0.8ml/min to 1,312ml/min at speeds of 10–250rev/min.

Key benefits of product application

  • Remote stop/start and speed control allowed the pump to be easily integrated into the automated windscreen sealing system.
  • Speed and flow rate are infinitely variable and the value of all adjustable parameters are indicated on a keypad with a twin-line alphanumeric display.
  • The Verderflex pump ensures easy tube loading and is stackable, self-priming and able to run dry.
  • The pump in use at Reliable Electrical Services doses 64ml/min consistently at 40rev/min, around the clock.
