Watson Marlow Peristaltic Pump 4 Roller Pumphead 314D

The Watson Marlow 314D (Part Number 133.4411.000) is a precision-engineered 4-roller pumphead designed for high-accuracy fluid transfer in laboratory and industrial applications. Known for its iconic "flip-top" design, the 314D series allows for rapid, error-free tube loading without the need for tools. The 4-roller rotor configuration is specifically chosen for applications requiring lower pulsation and higher dosing accuracy compared to standard 3-roller models, making it ideal for sensitive cell culture, pharmaceutical, and analytical processes.

Technical Performance and Design

• Enhanced 4-Roller Rotor: Features a 4-roller assembly that significantly reduces flow pulsation and increases volumetric accuracy for precise metering tasks.

• Flip-Top Tube Loading: The intuitive snap-fit design allows the track to be opened easily, enabling tubing changes in seconds and reducing downtime.

• Durable Construction: Built with a glass-filled polypropylene body and MoS2-filled Nylon 6 (Nylatron) rollers for exceptional chemical resistance and mechanical longevity.

• Precision Spindles: Utilizes electroless nickel-plated hardened steel spindles and carbon steel bearings to ensure smooth rotation and consistent compression.
