“Pumps for the food, pharmaceutical and cosmetic industries have some pretty special properties.” A separate requirement for pumps used in this industry is the materials used for producing them out have to be clean in order to they don’t generate any toxic mixtures. The material of the pump does not change the properties of the fluid. Manufacturing of pumps used in these industries must be inert materials, free of chemical reactions or oxidized upon contact with some high oxidising substances, pumps may resistant to the mixture of strong oxidizers and cold-hot temperature change.
In addition to choosing the pump not only met the flow criteria, the pressure column, a critical criterion given is that the pumped liquid should be carefully treated and after the pump must be cleaned easily.
Technical requirements of food and pharmaceutical pump:
The fabrication materials are completely smooth and do not have holes for food to cling to affect the quality of food.
The requirement for food pumps must have a surface roughness of between 3.2 and 0.4 μm.
The materials used in the pump must be stainless steel (316L stainless steel) is made by the monolithic molding technology
Standard of the food and pharmaceuticals pumps :
FDA: Foodstuffs and pharmaceuticals by US standards
EHEDG – Clean Equipment Design Group of Europe
QHD – Quality design
3-A – Sanitary standards
3A0 / 3A1: Sanitary / Industrial Standards (Ra ≤ 3.2 μm)
3A2: Sterile standard (Ra ≤ 0.8 μm)
3A3: Sterile standard (Ra ≤ 0.4 μm)
Products of the food pump designed optimally is easy to use in many areas such as:
Water industry: wine, juice, beer, beverage
Food industry: milk, oil, vegetable oil, olive oil, soy sauce, fish sauce, vinegar
Chemical industry: Acids, detergents
Pharmaceutical industry: emulsion, soap
Cosmetics industry: toothpaste, shampoo, shower gel, etc.
