Laboratory pump 300

dosingdispensingelectric

Overview
The 300 series cased benchtop pumps are laboratory-grade drives offering manual, remote, analogue (0–10 V / 4–20 mA) or RS232 control. Drives feature a chemically resistant ABS top, powder-coated casework and IP31 ingress protection. Four drive variants provide graduated control and functionality: 323Du (RS232/auto/manual, high-flow), 323U (analogue-auto/enhanced manual), 323S (high-performance manual) and 323E (manual).

Pumphead options available as standard (others available on request):

• 313D / 313D2 — three-roller pumpheads for continuous tubing
• 314D / 314D2 — four-roller pumpheads for continuous tubing
• 314MC — four-roller five-channel microcassette pumphead
• 318MC — eight-roller five-channel microcassette pumphead
• 501RL / 501RL2 — single-channel spring-loaded pumpheads for large-bore tubing

Features and benefits

• Control: manual keypad, remote TTL run/stop & direction, analogue 0–10 V or 4–20 mA, RS232 on applicable models
• Enhanced digital manual speed control up to 133:1 (model-dependent)
• Keypad lock to prevent accidental changes
• MemoDose function for accurate single-shot dosing
• Digital TTL inputs for run/stop and direction; instantly reversible
• Two-year manufacturer warranty

Performance highlights (examples from range)
313D three-roller: flows up to 2,000 ml/min (dependent on pumphead/drive and speed)
314D four-roller: flows up to 1,600 ml/min (dependent on pumphead/drive and speed)
