Watson Marlow 620 Du/R Peristaltic pump

• Dosing and metering of sensitive or abrasive fluids in pharmaceutical production.
• Transferring viscous slurries or shear-sensitive biological cultures in biotech labs.
• Handling corrosive chemicals or high-purity liquids in research and development.
• Integration into automated process lines for precise fluid control.
• Food and beverage processing for accurate ingredient addition or product transfer.

Flow Rate

For this class of equipment, flow rates typically range from microlitres to several litres per minute, offering a wide turndown ratio for precision.

Pressure Capability

Units of this type commonly handle pressures up to 2-4 bar, suitable for many dosing and transfer applications.

Power Supply

Typically operates on standard single-phase industrial power, such as 230V, 50Hz in the UK.

Control Interface

Commonly features analog (e.g., 4-20mA, 0-10V) and digital (e.g., RS485, Ethernet) interfaces for remote control and system integration.

Tubing Material Compatibility

Relies on the chemical compatibility of the peristaltic tubing with the fluid being pumped; various tubing materials are available.

Maintenance

Primary maintenance involves periodic replacement of the peristaltic tubing, which is a consumable item.

• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing. They are also self-priming, can run dry without damage, and provide precise, repeatable flow rates.

• How often does the tubing need to be replaced?

• Can this pump handle viscous fluids?

• Is this pump suitable for sterile applications?

• What kind of control systems can this pump integrate with?

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.
