Low-priced Peristaltic Pump
Rietschle Thomas Puchheim is now offering its proven peristaltic pump series SR25 with a stepper motor. The pump now offers a very broad control range and also allows for continuous operation. And all that for a competitive price.
The robust design makes revolutions up to 300 rpm’s possible; this results in a maximum flow of 428 ml/min. In order to effectively use the entire adjustment range the control circuit board is divided into four speed ranges.
In addition, the control board offers several options: clockwise or counter-clockwise operation, a digital speed indicator, a speed button, and a potentiometer. The pump can also be activated via personal computer with an analogue input signal (0 to 5 V).
Finally, an integrated circuit enabling 1/8th of a step, guarantees a smooth operation, particularly at low speeds. Thus the SR 25 peristaltic pump series works efficiently within the entire control range.
Typical applications for this pump are dosing applications, in the chemical and medical field as well as food and beverage.
