FAQs
- What is an air operated double diaphragm (AODD) pump and why is it used in sanitary processes?
-
An AODD pump is powered by compressed air and flexes two diaphragms to draw in and discharge fluid through check valves. With no mechanical seal in the product zone, it offers straightforward cleanability and gentle transfer across a wide range of viscosities. AODD pumps can run dry without damage and are limited by available air pressure (typically around 120 psi maximum), which suits many sanitary transfer duties.
- Which industries do your AODD pumps serve?
-
Food, dairy, beverage, brewery, home and personal care, biopharmaceutical, and chemical applications.
- Do you offer sanitary AODD pumps with hygienic certifications?
-
Yes. Select models meet 3-A and FDA requirements. Almatec Biocor series pumps are built in compliance with applicable hygienic standards including EHEDG, 3-A, FDA, and USP Class VI. See each series page for specific certifications.
- Are AODD pumps CIP or SIP-capable for hygienic cleaning?
-
Many air operated diaphragm pumps can be cleaned-in-place (CIP) or steamed-in-place (SIP). Capability depends on the series and configuration.
- Can AODD pumps handle shear-sensitive or solids-laden products?
-
Yes. AODD pumps provide gentle handling for shear-sensitive products and can handle high-viscosity fluids and large suspended solids, depending on the model and material/diaphragm selection.
- How do I choose the right AODD pump size and materials for my process?
-
Contact our team with product, temperature, viscosity, required flow/head, and any needed certifications for a recommendation.
- Do these pumps require electricity to operate?
-
No. Air operated double diaphragm pumps use compressed air rather than an electric motor at the pump.
- Can I buy an air operated diaphragm pump online from CSI?
-
Yes. You can buy and air operated diaphragm pump through our online store or call 417.831.1411 for selection help.
- Do you offer options for both hygienic and chemical transfer duties?
-
Yes. This category includes sanitary designs for food and biopharmaceutical use and configurations suited for chemical transfer. Materials and certifications vary by series.
