N/A General: Depending on the model, the Centry® Series centrifugal are available as standard with closed impellers. Closed impellers eliminate axial loads and extend the life of the motor bearings when the pump is close-coupled to the motor. Closed impellers simplify the axial positioning of the impeller, when using close-coupled sealed pumps.

Single Mechanical Seals:
Single mechanical seals are the most economical type of seal to use when leakage is not desired. When properly installed and maintained, these seals will generally give years of trouble-free service.

Double Mechanical Seals:
Double Mechanical seals are also available for the Liquiflo Centry® Series centrifugal pumps. This seal configuration relies on a barrier lubrication system to cool and lubricate the seal faces.

Magnetically-Coupled Pumps:
These offer a simple and cost-effective solution to sealing toxic, noxious, crystallizing or most other fluids that present problems for single seals and would therefore require use of a double mechanical seal. Magnetically coupled pumps eliminate the need for cooling loops that are required for double mechanical seals.
