Hygienic
For the highest standards of cleanliness, product safety, and process control
Air-Operated Double Diaphragm Pumps
For hygienic applications
Air-operated double diaphragm pumps (AODD) are also used in sensitive applications where media must be transferred safely, cleanly, and gently. They are suitable for pumping low-viscosity liquids as well as viscous or paste-like products and can be integrated flexibly into existing processes.
With the right choice of materials, matched sealing systems, and application-specific design, these pumps enable reliable pumping even in areas with increased requirements for cleanliness and product safety.
For demanding hygienic processes—reliable and gentle on your product.
