Hygienic Pumps

A hygienic pump is used in systems where cleanliness is vital to the product being pumped, such as food products, beverages, and pharmaceuticals. Hygienic pumps need to be able to be cleaned and sanitized on a regular basis and must be able to handle liquids gently. Indications that a pump is considered hygienic include certification of being an ATEX pump as well as other certifications.

The Viking hygienic pump with the highest pressure rating is our TRA®20 Series at 500 PSI. We encourage potential customers to contact their local distributor to discuss your specific application needs.

Viking's hygienic positive displacement pump products are manufactured both in Cedar Falls, Iowa, USA, and Eastbourne, UK.

Circumferential piston pumps handle high value shear sensitive liquids across hygienic applications where gentle handling, cleanability, and efficiency are paramount. Viking Pump Hygienic has a wide range of displacements with high pressure capabilities. It's ability to handle solids is excellent and has low shear characteristics across a wide range of product viscosities.

Rotary lobe pumps are the mainstay of many hygienic fluid handling applications where gentle handling & cleanability are of utmost importance. These pumps have a wide range of displacements, good solids handling capabilities, and low shear characteristics across a wide range of product viscosities. The non-contacting pumping principle for RLPs means no metal-on-metal contact, limiting pump wear regardless of product viscosity.

Centrifugal pumps can transfer large volumes of liquid, but efficiency and flow decrease rapidly as pressure and/or viscosity increases. Rotary pumps and circumferential piston pumps, on the other hand, offer higher efficiency wherein they move a consistent amount of liquid at a constant speed. They are gentle on liquids and have extremely low shear characteristics across a wide range of product viscosities.

Peristaltic pumps certainly have their place in the hygienic process, especially when handling fluids that will be infused with someone's blood (like IV fluid, for example). However, there are phases of the hygienic process that require gentle handling of the fluid being conveyed and the pulsation of a peristaltic pump could damage the product. That is why having a RL or CPP with consistent speed and flow is ideal, depending on the phase of production of the liquid.
