Watson Marlow 504u Mk2 Peristaltic Pump

• Accurate dosing and dispensing in laboratory environments.
• Sterile fluid transfer in biotechnology and pharmaceutical processes.
• Chemical addition and transfer where fluid integrity is critical.
• Low-shear pumping for sensitive biological fluids.
• Fluid handling in pilot plants and small-scale production.

Typical flow rate

Varies significantly with tubing size and drive speed; commonly ranges from microlitres to several litres per minute for this class of equipment.

Speed control ratio

Units of this type, such as the 504Du variant, typically offer a wide speed control ratio, often around 220:1, allowing for precise flow adjustment.

Enclosure rating

Many versions, including the 504U, feature an IP55 washdown-resistant housing, suitable for environments with splashing or low-pressure water jets.

Power supply

Typically operates on standard single-phase mains power, commonly 230V AC for the UK market.

Fluid contact materials

Only the tubing contacts the fluid, allowing for selection of chemically compatible and sterile tubing materials.

Control interface

Units commonly feature local manual control and often include a 6-pin port for remote control and automation integration.

Footprint

Designed for benchtop installation; typically compact for laboratory and process environments.

• What are the advantages of a peristaltic pump for pharmaceutical applications?

  Peristaltic pumps offer sterile fluid transfer as the fluid only contacts the tubing, reducing contamination risk. They also provide gentle, low-shear pumping suitable for sensitive biological materials and are easy to clean and maintain.

• Can this pump be used for continuous operation?

• What type of tubing is compatible with this pump?

• Is remote control functionality available?

• What maintenance is typically required for a peristaltic pump?

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.
