Being among the world's most crucial and hygienic operations, food-processing applications naturally demand the highest cleanliness standards – particularly when it comes to pumping products.
Engineered by Wilden® – the inventor of air-operated double-diaphragm (AODD) pumping technology – the Saniflo™ Hygienic™ Series AODD Pump is specifically designed to excel in food-processing applications handling low-acid, pasteurized and protein-based products.
But what makes the Saniflo Hygienic Series a better choice than other food-processing pumps? Here are four ways the Saniflo Hygienic Series sets the standard for simple, efficient, reliable and hygienic operation.
1. Reduced Air Consumption & Greater Flow Rates
At the heart of Saniflo Hygienic Series pumps is the Wilden Pro-Flo® SHIFT Air Distribution System (ADS). Equipped with the most energy-efficient and high-performance ADS on the market, the Saniflo Hygienic Series offers operators the following advantages:
Reduced air consumption by up to 60% while creating flow rates up to 34% greater than other AODD pump models
Easy access to the air valve to observe its condition without removing the pump from service
Due to its stall-free design, there is no need for full pump disassembly or hammer blows to repair or restart
2. Longer-Lasting Hygienic Diaphragms
Saniflo Hygienic Series pumps are optimized with Wilden Pure-Fuse™ Integral Piston Diaphragms (IPDs) – available in Saniflex™ (Hytrell®) and Wil-Flexl® (Santopene®) materials – designed for greater durability in food-processing applications.
Featuring a zero adhesive, one-piece design that offers a safe, clean and reliable product transfer with no product entrapment areas, Pure-Fuse Diaphragms provide the following advantages:
Up to 50% price reduction compared to PTFE laminate diaphragms
Up to 100% increased flow and suction lift compared to PTFE laminate diaphragms
Minimized product contamination risks by eliminating outer pistons where particles and bacteria can hide
Increased service life over standard diaphragm types by eliminating outer-piston wear
Reduced maintenance costs and improved facility safety by eliminating the risk of leaks
Additionally, Pure-Fuse™ Diaphragms utilize the same shaft and inner-piston hardware as standard Wilden pumps, making upgrades simple.
3. Easy-to-Clean, Clean-in-Place Design
Wilden Saniflo Hygienic Series AODD Pumps with Pure-Fuse Diaphragms are designed with the following advantages to help operators effectively clean, rinse and restart their processes with minimum downtime:
Easy cleanability with clean-in-place (CIP) capability and improved draining with wetted-path design
No need to remove the Pure-Fuse Diaphragms to clean behind the outer piston since there are no product entrapment areas
Meets strict cleanliness requirements and the highest hygienic standards in the industry, including 3A, ATEX, EC 1935/2004 and FDA CFR 21.177
Unlike other pumps that require clean-out-of-place (COP) procedures, Wilden Saniflo Hygienic Series Pumps with Pure-Fuse Diaphragms help food-processing operators reduce downtime and minimize cleaning efforts, resulting in significant cost savings.
4. Utility Pumping & Compatible Repair Kits
Saniflo AODD Pumps are designed to help operators increase operational efficiency and reduce inventory items. Due to its simple and effective design, the Saniflo Hygienic Series can also be used for other applications in food-processing facilities that do not involve food contact, such as chemical, water or other non-food product transfer. Here’s how:
Pro-Flo SHIFT ADS is used across the Wilden product line, which means that the 1.5” aluminum pump used to muck out sump uses the same air kit as the 3” Saniflo Hygienic Series pump transferring food product
Diaphragms and valve components used in the Saniflo Hygienic Series, while food-grade, can also be installed in standard pumps with no need to maintain separate inventories
Because the Saniflo Hygienic Series serves as a utility pump, operators of food-processing applications can take advantage of compatible repair kits, reduced inventory on hand and overall increased profitability.
Conclusion
With a multitude of operational advantages, it’s clear that Wilden Saniflo Hygienic Series Series AODD Pumps are a better choice for food-processing applications. To see the difference in action, watch the video: Introduction to Wilden Saniflo Hygience Series (HS) AODD Pumps.
