55 Series & Ultima Ultra Hygienic Rotary Lobe Pumps
For the very highest standards of sterile containment cleaning in-place (CIP) and steam-sterilising (SIP)
Applications Biotechnology Sterile pharmaceuticals Ultra-hygienic food processing Separation equipmentAseptic manufacturing Multi-product facilities Sanitary/hygienic production Sampling Benefits 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. Controlled-compression gasket-type joints and no O-rings in product contact. Shaft seal designcombines 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, for true aseptic processes. High efficiency to minimise damage to shear-sensitive low viscosity fluids.
Front-loaded single mechanical face-type seals of hygienic design. Materials include carbon and silicon carbide. Low-pressure flush seals use the same single mechanical seal with an additional housing. Double mechanical seals use all the components from single seals.
High specification taper roller bearings
