Viking’s thin liquid internal gear pumps handle low viscosity liquids with high efficiency, offering many advantages in applications normally associated with centrifugal pumps. These pumps are suitable for even non-lubricating or corrosive liquids with low viscosities. Viking pumps are self-priming and capable of reversible direction of flow, enabling use of one pump instead of two for loading/unloading or line stripping. The gear pump’s flow is directly proportional to input speed, allowing it to meter process liquids. Thin liquid models are available in iron, steel or stainless steel, with adjustable end clearances and idler gears of iron, non-galling 770 alloy or PPO composite. The pumps offer capacities up to 17m3/hr (75 gpm) and a pressure range of 0 to 7bar at viscosities from 0.1 to 4cSt, or up to 17bar at higher viscosities.
