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?

Yes, peristaltic pumps like the 504u Mk2 are designed for both continuous fluid transfer and precise dosing/dispensing applications. The longevity of the tubing will depend on the fluid, speed, and duration of operation.

What type of tubing is compatible with this pump?

The pump head is designed to accept specific tubing sizes and materials. Buyers should consult the manufacturer's specifications or the unit's manual to ensure correct tubing selection for their application and chemical compatibility.

Is remote control functionality available?

Many units in this series, including the 504u Mk2, are equipped with a remote control port, allowing for integration into automated systems for start/stop, speed control, and direction changes.

What maintenance is typically required for a peristaltic pump?

The primary maintenance involves regular inspection and replacement of the pump tubing, as it is a wear part. The frequency depends on usage, fluid type, and operating parameters. The rollers and housing may require occasional cleaning.

This listing is for 1 of 2 Watson Marlow 504u Mk2 Peristaltic Pumps

These units are in full working condition and ready for immediate release.

The Watson‑Marlow 504U is a peristaltic (tube) pump designed for dosing, dispensing, or fluid transfer in laboratory, process, and industrial settings. Because of its design, the fluid only contacts the tubing, which helps with chemical compatibility, sterility, and ease of cleaning/maintenance.

It features a fairly durable, washdown‑resistant housing (IP55) in many versions, allowing it to tolerate exposure to splashing or low‑pressure water jets.

A few variants (e.g., “Mk2” or “Du”) bring updates in control, enclosure, and durability

Other features:

The manual for the 504Du version describes that the pump’s speed control ratio is 220:1, giving a minimum speed of 1 rpm (for the 220 rpm drive) and 0.5 rpm (for 55 rpm version).

The pump is intended to be installed on a horizontal surface with good ventilation and free airflow around it.

The pump allows for remote control / automation through a 6‑pin port for auto/remote operation

Typical Specifications

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.
