Wilden PS4 (2" Tri-Clamp) Saniflo FDA AODD Pump

The PS4 Saniflo FDA pump is a stainless steel air operated double diaphragm pump that was designed by Wilden for small to medium sanitary processing facilities. It has 2" Tri-Clamp connections and features the durability, reliability, customization, and innovative technology that Wilden is known for. The PS4 uses up to 60% less air than its competitors due to the addition of the Pro-Flo SHIFT air intake system. This system prevents the air chambers from overfilling saving air, saving you energy and money. The PS4 meets FDA and ATEX requirements and is availabe in a variety of configurations to tailor it perfectly to every application. The Wilden pump lines are highly customizable. We have selected several standard popular models, however there are a variety of diaphragms, materials, and valves available. If you require a specific configuration or help tailoring the PS4 to your application, please contact our sales team. PS4 Saniflo Diaphragms All diaphragms are FDA compliant and other diaphragms are available upon request. Traditional Diaphragm Wilden's traditional "pie shaped" diaphragm is the industry standard for AODD pumps, it is durable and reliable. The traditional diaphragm comes standard in EPDM and Sani-Flex, but is also available in Wil-Flex, Polyurethane, Buna-N, Neoprene, and FKM upon special request. Full-Stroke IPD The Integral Piston Diaphragm (IPD) is a popular choice in the food, beverage, and chemical industries. This diaphragm does not have an outer piston, the piston is fully integrated into the diaphragm. It is ideal for applications involving abrasive product and harsh environments. The IPD meets higher sanitary standards as the integrated piston removes the cavity between the outer piston and diaphragm found in a traditional design. This also makes it easier to clean. Reduced stroke IPD is available upon request for applications with highly viscous products. The IPD diaphragm is available in Wil-Flex and Saniflex. EZ-Install Diaphragm The Ez-Install diaphragm is designed for applications where regular maintenance is required. The EZ-install diaphragm does not need to be inverted, making it easy to install as it can be accessed without specialty tools. Easier maintenance means less downtime, and lower maintenance costs. This diaphragm is a direct replacement for traditional diaphragms, with the same performance, durability, and footprint. The PS4 EZ-Install diaphragm comes standard in Wil-Flex but is also available in Saniflex, Polyurethane, and Bunalast. Full-Stroke PTFE Diaphragm The Full-Stroke PTFE Diaphragm is designed to handle a variety of different abrasive products and aggressive chemicals. PTFE is chemically inert and is recommended for acids, caustics, ketones, aldehydes, and acetate's. The PTFE diaphragm has increased displacement per stroke when compared to other diaphragms, resulting in enhanced flow rates and suction lift. This diaphragm has the same hardware and general design as the standard diaphragms, but has a more contoured shape and smooth surface than the TPE and rubber variations. Its unique shape and chemical and abrasion resistance makes this diaphragm ideal for aggressive applications. This diaphragm is available standard with Wil-Flex or Saniflex back-up material, while Buna, neoprene, and EPDM back-up materials are available upon special request.
