Two pump models are available, the 205S/CA manual control variable speed pump, and the 205U/CA auto and manual control variable speed pump. Both are fitted with tachometer-controlled servo-quality DC motors for precise speed control. A keypad lock prevents tampering or accidental changes and there is a maximum high speed priming function.

Flow control for each individual channel is provided by multi-turn "click-stop" pressure adjustment on each cassette. The 205CA pumphead with its snap-fit cassettes and sprung track is factory-set for standard applications,but lockable occlusion adjustment allows settings to be optimised when necessary and, uniquely, remain undisturbed during tube changes. 205CA pumpheads accept manifold pump tubing in six different materials and nineteen sizes.

0-5V DC tachometer output for speed monitoring, 5V auxiliary output for motor run indication. Remote low voltage, or TTL (PLC compatible) control of start/stop and direction. Selectable dual voltage 100-120V or 220-240V 50/60Hz operation.
