The pump drive of the model 120 of the Hei-FLOW Expert series can be operated with either single-channel or multi-channel pump heads. The flow rates with single-channel pump heads are in the range of 0.5- 936 ml/min; with multi-channel pump heads from 0.005 - 277 ml/min.
This model has a flow rate of 2.0 — 4,056 ml/min and is designed for operation with single-channel pump heads. The analog interface makes it possible that all functions can be controlled externally. A control accuracy of ±0.5% and a conveyor speed of 24 to 600 rpm provide optimum process conditions. In addition, sensitive media can be protected from influence by using the optional foot switch.Like all Heidolph peristaltic pumps, the conveying direction of this model can be changed by a simple push of a button. Furthermore, the accelerated filling and emptying of the tubing is simplified, since here only the button for the maximum speed has to be pressed.
