Do you know how they work and what types exist? What are the advantages? Next, we will discover all the keys to take into account to choose the most appropriate option for your business.
High-strength industrial pumps
Sanitary pumps are suitable for fluids with viscosities up to 200,000 cPs, including acids and abrasive chemicals. To guarantee a long service life, these pumps are made of austenitic stainless steels, with a minimum proportion of 16% chromium and 6% nickel.
AISI-316L stainless steel, a common material for the construction of industrial pumps, also contains molybdenum, which gives it extraordinary resistance to corrosion, high temperatures or acid pitting.
What type of sanitary pump do you need?
The current catalog of pumps for industrial use includes a wide range of equipment: industrial peristaltic pumps, lobe pumps, centrifugal pumps … If we focus on the category of sanitary pumps, lobe pumps represent the most popular solution today. These industrial pumps are able to meet the high demands required by these sectors, in addition to offering other interesting operational advantages.
What types of sanitary lobe pumps can we find on the market today? There are basically two main categories:
- Sanitary lobe pumps
Sanitary lobe pumps are indicated for flows rates up to 40 m3 / hour and working pressures up to 12 bars. These types of pumps feature high strength mechanical seals, made of silicon carbon, graphite or EPDM. The standard versions usually work with tri-lobe rotors, although there are also models with wedge-shaped bilobar rotors.
Furthermore, to guarantee optimum performance, these industrial pumps also offer additional options, such as NBR or VITON gaskets, safety by-pass valve or heating and cooling jacket.
- Hygienic lobe pumps
These types of pumps are designed for the most demanding applications, complying with the requirements of the European EHEDG Certification. Hygienic lobe pumps operate with lower flow rates than sanitary pumps, up to 12 m3 / hour, and pressures up to 12 bar.
Uses and applications of sanitary pumps
Regarding their industrial applications, sanitary pumps are a very suitable solution for pumping and transferring food products (dairy products, wines, juices, sauces, jams and concentrates, oils, glucose …) or cosmetic and drugstore products (creams, gels, shampoos, toothpaste perfumes, detergents, glycerin, etc.). Sanitary lobe pumps, like the ones you can find in Boyser, are also suitable for the chemical and pharmaceutical industries.
