Watson Marlow 520Di Peristaltic Pump

• Accurate dosing and dispensing in laboratory settings.
• Transfer of shear-sensitive or corrosive fluids in chemical processing.
• Metering of ingredients in food and beverage production.
• Biopharmaceutical fluid transfer and fermentation processes.

Typical flow rate range

For this class of equipment, flow rates typically range from microlitres to several litres per minute, depending on tubing size and drive speed.

Power supply

Units commonly operate on standard single-phase mains power, typically 110-230V, 50/60Hz.

Control interface

The 520Di model typically features a digital display and keypad for precise control and programming.

Tubing compatibility

These pumps are designed to accept a range of tubing materials and bore sizes to suit various applications and fluid types.

Ingress Protection (IP) rating

Commonly, units of this type offer an IP rating suitable for general laboratory or industrial environments, protecting against dust and splashes.

Footprint

Benchtop units like the 520Di typically have a compact footprint, suitable for laboratory benches or integration into process lines.

• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing, are gentle on shear-sensitive fluids, and provide accurate, repeatable dosing.

• Is this pump suitable for viscous fluids?

• What maintenance is typically required for a Watson Marlow 520Di?

• Can this pump be used for continuous operation?

• What kind of accuracy can I expect from a 520Di?

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.
