Watson Marlow 323 Peristaltic Pump

• Accurate dosing and metering in laboratory settings.
• Transfer of shear-sensitive fluids in biopharmaceutical processes.
• Chemical addition in water treatment plants.
• Sampling and analytical applications in environmental monitoring.
• Food flavouring and additive dosing in food processing.

Typical flow rate range

Units of this type commonly offer flow rates from microlitres per minute up to several litres per minute, depending on the pump head and tubing size.

Power supply

Typically operates on standard single-phase mains electricity, commonly 230V, 50Hz in the UK.

Control interface

Often features a digital display and keypad for precise control, with options for remote control via analogue or digital signals.

Tubing material compatibility

Designed to accommodate various tubing materials, such as silicone, Marprene, Bioprene, and Chem-Sure, to suit different fluid chemistries.

Pump head options

May be fitted with different pump heads (e.g., single channel, multi-channel) to optimise flow and pressure for specific applications.

Ingress Protection (IP) rating

Commonly features an IP rating suitable for laboratory or light industrial environments, protecting against dust and splashes.

• What is the primary advantage of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing, making them ideal for sterile or corrosive applications. They also provide precise and repeatable flow rates.

• Can this pump handle viscous fluids?

• What maintenance is typically required for a Watson Marlow 323?

• Is this pump suitable for continuous operation?

• How do I ensure the correct tubing size for my application?

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.
