Centrifugal chemical pumps are ideal for many applications, from filtration and circulation to storage and unloading.
Due to their harsh nature, corrosive chemicals must be handled carefully. As designers establish their systems, they must select pumps that are constructed to withstand the specific corrosive chemicals involved in their process.
Centrifugal Chemical Pump Types
Centrifugal pumps are available to transfer a wide range of flows. Using rotational energy supplied by an impeller, these pumps are able to move liquids safely and efficiently. Centrifugal chemical pumps are designed to transfer liquids that other pumps cannot safely handle.
Centrifugal chemical pumps are manufactured in two main styles: mechanically sealed and magnetically driven. These designs are distinct and are appropriate for different applications.
Pumps With Mechanical Seals
A centrifugal pump features an internal rotating impeller with a portion that connects to the motor through an opening in the pump housing. To prevent leakage, a mechanical seal is used for this opening. These are typically made of ceramic, silicon carbide or carbon rings that are carefully designed to seal the pump preventing leakage. One ring rotates as the shaft turns, while the other remains stationary in the pump. As the fluid travels through the pump, a small amount moves between these two seal faces to provide lubrication.
