A new range of hygienic internal gear pumps that provide features and benefits for pumping in food, brewing, pharmaceutical, fine chemicals and other ‘sensitive’ hygienic applications, has been introduced by gear pump specialists Viking Pump.
Available in the UK through Michael Smith Engineers, the positive displacement Viking Hygienic Series represents a breakthrough in combining the reliability and ease of maintenance of an internal gear pump with the clean-ability of a hygienic pump. The Hygienic Series is also third-party-certified to display the 3A Sanitary Standards Symbol for positive rotary pumps (3-A Sanitary Standard 02-11) a globally recognised standard for hygiene within the food and dairy industries.
Features include only one shaft seal (unlike the two usually found in most other types of hygienic positive displacement pump), which reduces the possibility of unplanned downtime and associated costs, internal wetted surfaces polished to a minimum of Ra 0.8µm and internal angles machined to a minimum radius of 0.8mm.
The Hygienic Series has sealed bearings with food-grade grease, so no need for an oil reservoir or oil changes. Also, the pumps incorporate front removable rotor, shaft seal and casing to enable fast disassembly and reassembly for cleaning and inspection and have double seal flush/quench ports as standard to enable in-situ change from single to double seals.
