What is a peristaltic pump and how does it work?

A peristaltic pump uses rollers to compress and release a flexible tube, creating a vacuum that draws fluid through. This action moves fluid without the pump mechanism contacting the fluid itself.

Why would I choose a peristaltic pump over other pump types?

Peristaltic pumps are ideal for applications requiring sterile, non-contaminating, or shear-sensitive fluid transfer. They are also excellent for viscous, abrasive, or corrosive fluids as the fluid only contacts the tubing.

What does 'L/S' mean in Masterflex L/S?

'L/S' stands for 'Laboratory/Standard' and refers to a specific range of tubing sizes and pump head designs within the Masterflex system. This ensures compatibility between pump heads, drives, and tubing.

Is a pump head included with this unit?

The description states this unit is supplied with no pump head. Buyers will need to source a compatible Masterflex L/S pump head separately to operate the unit.

What maintenance is typically required for a peristaltic pump?

The primary maintenance involves regular inspection and replacement of the tubing, as it is the only component in contact with the fluid and subject to wear. The drive unit itself typically requires minimal maintenance.

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. The flow rate may vary with viscosity, and tubing selection can optimise performance.
