Watson Marlow 520S Peristaltic Pump

• Precision dosing and metering in laboratory and pilot plant settings.
• Transfer of shear-sensitive biological fluids and cell cultures.
• Handling of corrosive chemicals and abrasive slurries in industrial processes.
• Dispensing of viscous liquids in food and beverage production.
• Sterile fluid transfer in pharmaceutical and biotech manufacturing.

Typical flow rate range

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.

Speed control

Units of this type typically offer a wide speed control range, often with fine increments for precise flow adjustment.

Power supply

Commonly found with universal voltage input, such as 100-240V AC, 50/60Hz, allowing for global compatibility.

Control interface

Typically features a membrane keypad for manual control, including speed, direction, and start/stop functions.

Fluid contact materials

Only the tubing contacts the fluid, with various tubing materials available to suit different chemical compatibilities and application requirements.

Maintenance

Maintenance is generally low, primarily involving periodic replacement of the pump tubing.

• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing. They can handle a wide range of fluids, including viscous, shear-sensitive, and corrosive materials, and can run dry without damage.

• Can this pump be used for continuous operation?

• What type of tubing is compatible with this model?

• Is this unit suitable for sterile applications?

• Does this pump come with a pumphead?

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.
