The Impeller: Why It Could Be Called The Heart Of The Bioreactor

An open impeller has a hub with attached vanes and is mounted on a shaft. The vanes do not have a wall, making open impellers slightly weaker than closed or semi-closed impellers. However, as the side plate is not fixed to the inlet side of the vane, the blade stresses are significantly lower. In pumps, the fluid enters the impeller's eye, where vanes add energy and direct it to the nozzle discharge. A close clearance between vanes and pump volute or back plat… WebOpen - The right impeller below has a completely open space between each blade that allows for easy CIP, but provides less power than disk impellers.
