55 Series & Ultima

Fully self-draining pump head: no hold-up of process liquid or cleaning agents. Rapid de-contamination and product change-over. External rotor fixing - no internal crevices. Low-carbon 316L stainless-steel for maximum corrosion resistance. Hygienic seal ring for all static seals instead of O rings.

Shaft seal design combines highest levels of containment with total product draining, no cavities, and front access for easy inspection and fast maintenance. Standard surface finish: 0.8µm (150 grit), with 0.5µ (240 grit) and electropolish options. Optional steam/sterile fluid barriers on joints and front cover sealing, for true aseptic processes. High efficiency to minimise damage to shear-sensitive low viscosity fluids.
