What is the primary benefit of a peristaltic pump for dispensing?

Peristaltic pumps offer high accuracy and gentle fluid handling, making them ideal for sensitive or sterile applications where product integrity is crucial.

Can this pump handle different fluid viscosities?

Yes, peristaltic pumps are well-suited for a wide range of fluid viscosities, from aqueous solutions to highly viscous gels, without compromising accuracy.

Is this unit suitable for cGMP environments?

Units like the 520Di are designed with features such as batch record output and validation support documents (IQ/OQ protocols) to meet cGMP requirements.

What kind of maintenance does a peristaltic pump typically require?

Maintenance primarily involves routine inspection and replacement of the peristaltic tubing, which is a wear part. This is generally a straightforward process.

Can this pump be integrated into an automated system?

Yes, units of this type commonly feature digital I/O and remote operation capabilities, allowing for integration into automated production lines or control systems.
