Speed Control Precision: Variable speed range from 0.1 rpm to 360 rpm with fine resolution of 0.1 rpm, yielding an impressive 3,600:1 turndown ratio
Pumphead Configuration: Typically features a LoadSure continuous tubing pumphead with four driven rollers—minimizing tube wear and maximizing lifespan
Control & Operation
User Interface: Equipped with a membrane-style keypad (numeric and function keys) for intuitive manual control, direct flow entry, speed calibration, and use of the “MemoDose” feature for one-off dosing
Remote Control Capabilities:
UN variant: Accepts analogue inputs (0–10 V, 4–20 mA), industry logic, and offers speed feedback (0–1478 Hz)
GlobalSpec Datasheets
DuN variant: Adds PIN-secure settings, network control via RS‑485, and dual analogue inputs for advanced metering control
Security: Dual-level process protection through PIN access ensures operational safety and prevents unauthorized alterations

Watson Marlow 520S Peristaltic Pump
Watson Marlow520S
Call
Condition: used, This listing is for a Watson Marlow 520S Peristaltic Pump. (1 of 7 Available)
The unit is in full working condition and is ready for immediate release.
Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to
clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the
pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic
pumps can operate dry without risk.
Easy to install, simple to operate and inexpensive to maintain, peristaltic pumps are ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. Suitable for metering, dosing and dispensing applications.
520S drive offers manual control via a large-key membrane keypad: speed adjustment; run and stop; forward/reverse; "Max" key for rapid priming and purging.
Supply voltage/frequency: 100-120V/200-240V 50/60Hz
