Specialty Series

Wilden’s Specialty Series Pumps are uniquely designed for specific markets and applications where a standard diaphragm pump could not meet performance requirements.

Wilden® Saniflo™ Hygienic™ Series Pumps for Hygienic and Sanitary Applications

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 and FDA CFR 21.177.

• Free-draining flow path for CIP capabilities.
• 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.

Wilden® High-Pressure Series Pumps for High-Pressure Applications

Wilden® High-Pressure Series Air-Operated Double-Diaphragm (AODD) Metal Pumps are equipped with a specialty air distribution system (ADS) that utilizes a double-acting power piston and Duplex technology to intensify fluid discharge pressure. Wilden high-pressure pumps can reliably deliver pressure performance of up to 20.7 bar (300 psig), making them perfect for a wide variety of high-pressure duties, including filtration, chemical sludge transfer and other viscous, solid-laden slurries.

• Simplex and Duplex technology available (depending on the size).
• Industry’s only 3″ high-pressure pump.
• Builds up to 300 psi discharge pressure.
• Built-in internal pressure amplifier with limited external piping for a more robust design.
