Watson Marlow 530S Peristaltic Pump

• Precise fluid metering and dosing in laboratory and pilot plant settings.
• Transfer of shear-sensitive or viscous fluids in biotech and pharmaceutical processes.
• Handling corrosive or abrasive chemicals where fluid isolation is critical.
• Dispensing and filling applications in food and beverage production.
• Water and wastewater treatment for chemical addition.

Typical flow rates

For this class of equipment, flow rates commonly range from microlitres per minute up to several litres per minute, depending on the pumphead and tubing size.

Power supply

Units of this type typically operate on standard single-phase mains power, commonly 230V, 50/60Hz in the UK.

Control interface

The 530S model typically features a user-friendly keypad and display for local control, with options for remote analogue and digital control.

Tubing compatibility

Designed to accommodate a range of tubing materials (e.g., silicone, Marprene, Bioprene) and sizes to suit various chemical compatibilities and pressure requirements.

Pumphead options

Commonly compatible with multiple pumphead types, allowing for flexibility in flow rate and pressure performance.

Ingress Protection (IP) rating

For cased industrial pumps, an IP rating suitable for general laboratory or light industrial use is typical, protecting against dust and splashes.

• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer fluid isolation, meaning the fluid only contacts the tubing, which reduces contamination risk and simplifies cleaning. They also provide gentle pumping action for shear-sensitive fluids and have a good turndown ratio for precise flow control.

• Is this pump suitable for continuous operation?

• What kind of maintenance does a peristaltic pump require?

• Can this pump handle abrasive fluids?

• What is meant by 'turndown ratio'?

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.
