Main Applications
AHLSTAR end suction single stage close coupled cen-trifugal pumps are designed for industrial applications to pump: •Clean and slightly contaminated liquids•Viscous liquids•Fibrous slurries•Non-fibrousslurries•Liquids containing large solids
The pumps are also suited to the pumping of liquids with a high gas content of up to 40% of free gases or up to 70% of bound gases.
