描述: Models PD 5201 and PD 5206 for advanced requirements. Peristaltic pumps are ideal for transporting and metering aggressive, abrasive, or corrosive solutions, and also for sterile media under low pressure. The medium to be transported only comes into contact with the tubing, so there is no contamination. Suitable for transporting highly viscous media up to 10000 mPas. The pumps are self-priming without seals or valves. Can be used in the food industry for filtering and separating, for water treatment, in biotechnology and routine laboratory applications. Media can be transported under pressure and under vacuum. Maintenance-free motors ensure long service life. Quantities displaced by the pump heads are stored in the program depending on the individual tubes used, and are shown in the digital display. Software may be ordered separately as an accessory. The pump drive is microprocessor-controlled. Equipped with RS232 digital interface; speed, metered quantity, flow rate, pause, and tube dimension can be controlled. Digital display of speed (min⁻¹) and flow rate (ml/min). Digital display of displacement volume (ml) in the case of volume metering. Intermittent metering is available with adjustable pause times. A metered volume can also be specified in addition to the flow rate display. Extremely simple calibration of displacement volume (ml) and flow rate (ml/min).
