SP Series of Self-Priming Liquid Ring Pumps… The Choice for CIP Return

The Ampco SP Series self-priming liquid ring pumps are ideally suited for products with entrained air and CIP return applications. Planned or unplanned, entrained air (gas mixed with a process liquid) is the cause of noise, vibration, seal failure, general performance reduction, or eventual pump failure.

Designed to handle entrained air conditions while maintaining specified performance and efficiency levels, the SP is built with extremely tight manufacturing tolerances.

A unique vane-shaped or wagon wheel style impeller design makes the SP capable of handling shear sensitive products efficiently while maintaining peak pump performance.

Seal options include single or double external mechanical seals, and all SP pumps are provided with 304 stainless steel adaptors as a standard to resist corrosion.
