Features and Benefits

Saniflo™ Hygienic™ Series (HS) pumps are uniquely designed for high-cleanliness requirements and feature a free-draining flow path that enables clean-in-place (CIP) capability. The HS flow-through liquid-path design also eliminates any potential areas where product residue can be trapped and contaminate the product. They are perfect for low-acid, pasteurized and protein-based products all the way up to biopharmaceutical sterile processes. HS pumps also meet the highest standards and requirements in the industry, including 3A, ATEX, EC 1935/2004, USP Class VI* and FDA CFR 21.177.

*USP Class VI certification is available only for Saniflo HS pumps with PTFE elastomer options
  • Featuring energy efficient Pro-Flo® SHIFT ADS
  • Free-draining flow path for CIP capability
  • Easy assembly with self-centering ball cages
  • Permanent or rotatable stand for cleaning
  • Multiple valve options: ball, mushroom, or flap for different application requirements
  • Shear sensitive
  • Greater flow - more gallons pumped per SCFM
