Watson Marlow 620S Peristaltic Pump

• Accurate dosing and transfer of shear-sensitive or viscous fluids in laboratory and pilot plant settings.
• Chemical metering and transfer, particularly for corrosive or abrasive liquids where pump integrity is critical.
• Food and beverage processing for flavourings, additives, and delicate product transfer.
• Pharmaceutical and biotechnology applications requiring sterile or hygienic fluid handling.
• Water and wastewater treatment for chemical addition and sampling.

Typical Flow Range

For this class of equipment, flow rates commonly range from approximately 0.001 L/min up to 18 L/min, depending on the pump head and tubing configuration.

Pressure Capability

Units of this type typically handle pressures up to 4 bar (60 psi) with appropriate tubing and pump head selection.

Speed Control

Fine speed control is commonly available, often from 0.1 to 265 rpm, with high accuracy for precise dosing.

Power Supply

Typically designed for dual voltage operation, commonly 100-120 V or 200-240 V, 50/60 Hz, making them suitable for various industrial environments.

Pump Heads Supported

This model commonly supports interchangeable pump heads such as the 620R Mk II for continuous tubing and 620RE/620RE4 for LoadSure elements, offering flexibility in application.

Tubing Compatibility

Compatible with a range of tubing materials (e.g., Marprene, Bioprene, Sta-Pure, silicone) and inner diameters, typically from 6.4 mm to 17 mm.

Enclosure Rating

Units in this series commonly feature an IP31 or NEMA 2 rated enclosure, suitable for dry industrial environments.

• What are the primary benefits of a peristaltic pump like the 620S/R?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing. They are also well-suited for viscous, abrasive, or shear-sensitive fluids and provide accurate, repeatable dosing.

• Can this pump handle different types of fluids?

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a peristaltic pump?

• Are spare parts and tubing readily available for this model?

Peristaltic pumps are valued in laboratory and pharmaceutical settings for their gentle, non-contact fluid handling, making them suitable for delicate samples and sterile applications. When buying used units, buyers typically prioritise checking tubing condition, motor functionality, and calibration history. Industry sentiment favours these pumps for their reliability, low maintenance requirements, and consistent flow rates. Common strengths include versatility across various fluid viscosities and compatibility with corrosive or shear-sensitive media. Prospective buyers should verify spare parts availability for specific models.
