Product Description

MRC Impeller No. 23

is a four-blade collapsible impeller designed for blending, homogenizing, dissolving, and suspension work in vessels with narrow openings. Its hinged blades fold inward for insertion through a restricted vessel neck, then swing outward during rotation to provide a working diameter of 140 mm (5.51 in.).

Applications

Narrow-Neck Vessel Mixing

Designed for insertion into bottles, flasks, carboys, reactors, and other vessels where a fixed 140 mm impeller cannot pass through the available opening.

General Liquid Blending

Provides broad engagement with the batch after the blades open, supporting routine blending of compatible low-to-moderate-viscosity liquids.

Dissolving and Homogenizing

Suitable for dissolving soluble ingredients, evening out concentration differences, and promoting more uniform composition throughout the vessel.

Suspension Maintenance

The deployed blades can help maintain compatible solids in suspension and reduce settling during laboratory and small-batch processing.

Restricted-Access Reactors and Containers

Useful where the impeller must pass through a limited access port before opening inside a larger vessel body.

Features

• Four hinged blades fold inward for insertion through narrow vessel openings.
• Blades swing outward during rotation to form a broad working profile.
• Designed specifically for vessels with restricted necks or access ports.
• Suitable for blending, dissolving, homogenizing, and suspension-maintenance tasks.
• Allows the impeller to remain attached to the shaft during insertion and removal.
• Collapsible construction eliminates the need to assemble a full-size fixed impeller inside the vessel.

FAQs

What type of impeller is the MRC Impeller No. 23?

It is a four-blade collapsible impeller designed to pass through a narrow vessel opening and expand to a 140 mm (5.51 in.) working diameter during rotation.

How do the blades open?

The blades pivot outward around their hinges as the shaft rotates. Centrifugal force and fluid resistance hold them in the deployed position while the impeller is operating.
