Watson Marlow 313DW Peristaltic Pump Head

• Accurate and contamination-free chemical dosing and transfer in laboratory and industrial settings.
• Precise liquid dispensing in pharmaceutical and biotech research and development.
• Fluid transfer in food and beverage processing, particularly for shear-sensitive or viscous liquids.
• Sampling and metering in environmental monitoring and water treatment plants.

Typical flow rate

Up to 2,000 mL/min for this class of pump head, depending on tubing size and drive speed.

Tubing compatibility

Commonly accepts 1.6 mm wall thickness tubing with bore sizes typically ranging from 0.5 mm to 8 mm.

Roller configuration

This model typically features a three-roller mechanism for higher flow rates, with four-roller options available for reduced pulsation.

Materials of construction

Typically built with durable, chemical-resistant materials such as glass-filled polypropylene, IXEF, and MoS₂-filled nylon for long service life.

Extension capability

Units of this type commonly allow for the addition of multiple extension pump heads, depending on tubing and drive specifications.

Maintenance

Features a rapid-load, flip-top design for quick and tool-free tubing changes, simplifying routine maintenance.

• What is a peristaltic pump and how does it work?

  A peristaltic pump works by compressing and relaxing a flexible tube, creating a vacuum that draws fluid through. This design ensures the fluid only contacts the tubing, preventing contamination of the pump mechanism.

• What are the advantages of using a peristaltic pump head like the 313DW?

• Can this pump head be used with different tubing sizes?

• Is this pump head suitable for continuous operation?

• What kind of drive unit is required for this pump head?

Pump heads and accessories are valued for their reliability and compatibility with established laboratory and biotech systems. Buyers typically prioritize condition of seals, tubing compatibility, and flow rate specifications when purchasing used units. Common strengths include longevity when properly maintained and availability of replacement parts. Key considerations include verifying previous calibration records, checking for corrosion or wear, and confirming material compatibility with intended fluids. Industry sentiment favours reputable manufacturers known for precision engineering and robust construction.
