Internal gear pumps have been used for more than 100 years on low-hazard foods like chocolate, confectionary, oils and sweeteners, and are now available in truly hygienic models suitable for dairy, egg, meat, processed foods and FDA-regulated personal care products.

This new series of positive displacement pumps, from 1 to 320 GPM, has only one shaft and one shaft seal. It eliminates the need for timing gears and one of the two shaft seals found in most hygienic pumps, greatly simplifying and reducing costs of installation, operation and maintenance.

These pumps are authorized to display the 3A Sanitary Standards Symbol for Centrifugal and Positive Rotary Pumps (3-A Sanitary Standard #02-09), a globally recognized standard for hygiene within the food and dairy industries.  With radiused internal angles, polished stainless steel surfaces, O-ring sealed joints and a behind-the-rotor seal, the pump eliminates areas of product entrapment. An easy-to-remove head, rotor and front-loading seal enables Clean-Out-of-Place (COP) cleaning methods.

This series also holds Type EL Class 1 certification from the European Hygienic Engineering and Design Group (EHEDG), which ensures that the pump is suitable for Clean-In-Place (CIP) cleaning methods. This in-place cleanability is validated through actual bacterial challenge testing. For facilities which COP today, but may convert to CIP at a later date, Viking Pump offers the ability to do either or both.


This series offers opposite (in-line) porting in either horizontal or vertical (for self-draining) configurations, as well as 90° ports for mounting directly under tanks with side discharge. ANSI-compatible flange ports are available as drop-in replacements for existing Viking pumps and others with a common footprint. Seal options include single or double O-ring seals and single or double mechanical seals. Jacketing options are available for melting chocolate and other solids before startup.
