Viking Pump

Rotary gear pumps are generally used to pump clean fluids that are not suitable for a centrifugal pump due to viscosity or control reasons.  Rotary gear pumps do not handle solids well and generally need the viscosity of the fluid to lubricate the rotor and idler gears and bushing that otherwise would wear prematurely due to metal to metal contact.  Rotary gear pumps use metallic and/or nonmetallic components depending on the application and are used in a wide range of markets and services.

Vane pumps operate using self-adjusting vanes in the rotor that maintain close clearances with the stator. Vane pumps are self-priming and also have excellent run dry capability when using non-metallic vanes. Vane pumps are used in a wide range of oil & gas, chemical, marine, power and several other general industrial applications and markets and are available in both sealed and sealless designs.

Sealless refers to the absence of a dynamic seal where the pump shaft penetrates the pump casing.  Sealless pumps are either the magnetically driven or canned motor designs.  Hose pump designs are also inherently sealless.  Sealless pumps are used for various reasons, but mostly when pumping volatile or toxic liquids where any amount of leakage cannot be tolerated.

Viking Pump’s external gear GB-410 Series™ and GB-414 Series™ products offer a robust and reliable pumping solution, engineered specifically for the rigorous application conditions for triethylene glycol (TEG) natural gas dehydration systems.
