Watson-Marlow 720S Cased-Drive Peristaltic Pump with Variable Speed Control and IP66 Enclosure
Product Description
The Watson-Marlow 720S peristaltic pump is a robust cased-drive pump designed for demanding industrial and laboratory environments, including harsh washdown applications. It belongs to the 700-Series, featuring a NEMA 4X (IP66) rated enclosure that provides exceptional protection against dust and water ingress, making it suitable for biotechnology bioprocessing and molecular diagnostics workflows where contamination prevention is critical.
Key technical specifications include:
- Flow rate: Up to 8.8 GPM (approx. 2,000 L/h) at 2 bar (30 psi) pressure for primary pumpheads; extension pumpheads maintain flow at reduced 1 bar (15 psi) pressure
- Speed control: Precise variable speed from 0.1 to 360 rpm with 0.1 rpm resolution, delivering a 3,600:1 turndown ratio for fine flow adjustment essential in synthetic biology and biopharmaceutical production
- Pumphead: Typically equipped with a LoadSure continuous tubing pumphead featuring four driven rollers that minimize tube wear and extend tubing lifespan, crucial for continuous gene editing and cell culture processes
Control and interface features:
- User interface: Membrane-style keypad with numeric and function keys, enabling manual control, direct flow input, speed calibration, and the “MemoDose” one-off dosing function
- Remote control: UN variant supports analogue input signals (0–10 V, 4–20 mA), logic control, and speed feedback (0–1478 Hz); DuN variant adds PIN-secure settings, RS-485 network control, and dual analogue inputs for advanced dosing and metering needs
- Security: Dual-level process access control via PIN to prevent unauthorized parameter changes, ensuring process integrity in sensitive molecular biology and clinical diagnostics setups
Construction and maintenance:
- Enclosure: Durable IP66/NEMA 4X rating ensures resistance to rigorous industrial washdowns and harsh lab environments
- Consumables: Only the tubing contacts fluid, simplifying maintenance and reducing contamination risks—ideal for biomanufacturing and sterile live-cell imaging applications
- Weight: Ranges from approximately 18.5 kg (drive unit only) to 31.5 kg with pumpheads, balancing portability and stability for bench or pilot-scale use
This pump supports precise fluid handling, widely adopted in biotechnology research fields such as bioprocessing, gene editing protocols, and synthetic biology experiments requiring reliable and contamination-free pumping solutions.
