Wobble Pump

Barr + Wray Range wobble pumps work solidly in many industrial sectors.

Wobble Pump

They efficiently transfer liquids of all viscosities, even with a high proportion of solids. Unlike conventional Progressive Cavity pumps they have a rotating unit with only one joint, hence why the ‘wobble’.

Key Facts

Conveying Capacity – Up to 10m3/hr
Pressure – Up to 4 Bar

Features + Benefits

Rotating unit with only one joint
Easy to maintain and economical due to a simple pump design
Quick replacement of the conveying elements due to the rotating unit only having one joint
Space saving – short compact design with directly flange mounted drive (block type)
