2″ | 51 mm Saniflo Hygienic Pro-Flo SHIFT Series Clamped Metal Pump
Wilden PS8 Saniflo Hygienic Series Clamped Metal 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 bio-pharmaceutical sterile processes. HS pumps also meet the highest standards and requirements in the industry, including 3A, ATEX, EC 1935/2004, FDA CFR 21.177 and 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
