The internal gear pumping principle was invented by Jens Nielsen, one of the founders of Viking Pump. It uses two rotating gears which un-mesh at the suction side of the pump to create voids which allow atmospheric pressure to force fluid into the pump. The spaces between the gear teeth transport...

Designed exclusively to handle ammonia and other low vapor pressure fluids in both refrigeration and transfer applications, these pumps are operated at low speeds to minimize flashing. They feature double mechanical seals with pressurized seal chamber and oil reservoir to prevent release of gas to...

The LP Gas series pumps are designed and UL listed for handling LP gas (propane) or butane for intermittent transfer applications such as bottle filling, vehicle fueling, bulk plant transfer and truck-mounted service. All feature mechanical seals and pressure relief valves. The larger sizes feature...

The Abrasive Liquid series pumps are designed to maximize pump life handling paints, inks, waste oil, and other abrasive liquids. With tungsten carbide bearings and silicon carbide behind-the-rotor mechanical seals, as well as other hard materials of construction, these pumps have doubled and...

The General Purpose Pumps utilize a simple and economical "floating rotor" design, in which the rotor/shaft is not retained by a thrust bearing, and is allowed to "float" within the pump head. This reduces the available pressure and allowable viscosity compared to a thrust bearing design like the...

Viking Duplex Fuel Oil Systems are factory engineered and built to order for oil transfer applications such as fueling diesel generators, fuel oil filtration, or oil re circulation. These systems can be provided with or without UL-CSA electrical control panels and include all strainers, check...

Viking Lid-Ease® strainers provide protection for any pumping system by preventing solids or foreign materials from entering the pump. Simple lid rotation disengages the breech lock lid, permitting easy, top removal of the basket for cleaning. The inner stainless steel screen is rigidly supported...

Gear Reducers to reduce a driver's synchronous speed to the speed required by the pump or other driven device.  Viking offers three sizes of offset helical gear reducers to reduce standard driver speeds to match pump (or other driven equipment) requirements. Adjustment slots on the mounting...

These motors can be directly coupled to Viking pumps for compact fluid transfer units (Power Transfer Units). These PTU's are ideal for mobile pump applications where an electric motor driver isn't practical (truck mounted oil delivery pumps for example).

Vane pumps are used for liquid transfer applications from chemicals to liquefied gases. Vanes extend from slots in the rotor, sweeping liquid through a cam-shaped cavity. The vanes provide very low slip and high volumetric efficiency. 

Rotary lobe pumps use timing gears to eliminate contact between the rotors, which allows their use on non-lubricating fluids. Various rotor forms are available, including bi-wing (shown at left) and multi-lobe options. These pumps offer low shear and gentle handling of the liquid to minimize...

Viking Hydraulic Pumps feature precise tolerances and reduced clearances within the pump to provide high pressures for fluid power applications. They are also used for high pressure industrial transfer and metering applications on clean, filtered, lubricating fluids. Mounting options include foot...

Designed exclusively to handle ammonia and other low vapor pressure fluids in both refrigeration and transfer applications, these pumps are operated at low speeds to minimize flashing.
