200 series cased pump
200 series multi-channel scientific pumps provide high-precision pulsation-free pumping. Two pump models are available, the 205S/CA manual control variable speed pump, and the 205U/CA auto control variable speed pump. Fitted with tachometer-controlled servo-quality DC motors, both pumps have precise speed control capabilities. A keypad lock prevents tampering or accidental changes, and there is a maximum high-speed priming function.
Multi-turn 'click-stop' pressure adjustments on each cassette, enable flow control for each channel. The 205CA pumphead with its snap-fit cassettes and sprung track is factory-set for standard applications. 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.
0-5 V DC tachometer output for speed monitoring, 5 V auxiliary output for motor run indication. Remote low voltage, or TTL (PLC compatible) control of start/stop and direction. Selectable dual voltage 100-120 V or 220-240 V 50/60 Hz operation.
Pumphead options available as standard:
205CA eight-roller low pulse cassette pumpheads with 4, 8, 12, 16, 20, 24 and 32 channels for manifold tubing
