Plugged Impellers
In certain applications, such as pneumatic conveying, plugged impellers may be needed to keep material from building up in the rotor and creating an imbalance. RAM, RCS, and RAS units can be supplied with plugged impellers with additional cost and lead time. Contact us to discuss your application with one of our professional application engineers.
