Sanitary Air Operated Double Diaphragm (AODD) pumps are widely used in pharmaceutical manufacturing. Ranges such as Graco Saniforce and the Enviroflex EF Series have smooth, cleanable wetted parts, handle shear-sensitive products gently and cope with a wide range of viscosities.
Where compressed air is not wanted, an electrically driven diaphragm pump such as the Graco Quantm or Dellmeco DME offers the same gentle handling. Flexible impeller pumps suit lower-pressure transfer of thin liquids, and sanitary drum pumps make it simple to empty containers without contaminating the product.
Pharmaceutical products must stay free from contamination, and pumps need to be cleaned thoroughly between batches. A pump with hard-to-clean areas or unsuitable materials can compromise product quality and compliance. Choosing a pump designed for sanitary duty protects your product and makes cleaning and validation much simpler.
