Diaphragm Pumps, Self Priming

Saniflo HS Pumps and Shear Sensitivity

Wilden HS pumps provide delicate, shearsensitive operation and gently transfer products. AODD pumps are among the safest and gentlest because the fluid is simply drawn into a chamber and then pushed out with no contact to moving parts. This low-shear operation ensures product quality is not damaged or compromised, resulting in the proper transfer of critical high-value fluids and materials.

Wilden Saniflo™ Hygienic Series Pumps: One-Of-A-Kind Design
The unique design of Wilden Saniflo HS pumps incorporates a free-draining flow path that optimizes performance and enables CIP capability while lowering the risk of cross contamination or compromised finished product that may lead to costly recalls. CIP is critical to hygienic-process success because it eliminates the need to disassemble the equipment to properly clean the pump, which costs the end
user time and money between runs.

Free-Draining Flow Path
Saniflo HS have been specifically designed for superior drainability thanks to the free-draining flow path. The pumps can quickly and
easily be drained without the need to disassemble the pump. With these state-of-the-art design features that help simplify cleaning,
HS pumps are the only US manufactured pumps in the industry to have earned 3A certifications for CIP operations.

Tri-Clamp®
Pump performance can be further optimized through the use of patented Tri-clamp® -style fittings that have been designed with an eccentric
cartridge check valve assembly, allowing for ease of maintenance by ensuring liquid chambers and pump manifold alignment. HS pumps also feature wash-friendly clamp bands with wetted path material of 316L stainless steel with an Ra 0.8 μm (32 μ-in) interior polish for ease of cleaning. DIN and SMS connections also available.

CIP Stand
For ease of maintenance and cleaning, Wilden offers an optional swivel pump to be drained by rotating the pump so that the fluid can flow
out of the discharge and into a suitable container. The swivel stand also permits the pump to be drained without disassembly.
