Viking AK190 Rotary Gear Pump 2-1/2" NPT

The Viking AK190 is a robust rotary gear pump designed for handling viscous fluids in industrial applications such as oil transfer, chemical processing, and lubrication systems. Manufactured by Viking Pump Co. of Canada Limited, this positive displacement pump features internal gears that provide consistent flow rates with minimal pulsation, making it ideal for metering and transfer duties. Key benefits include high efficiency in pumping high-viscosity materials up to 500,000 SSU, self-priming capability, and reversible operation for versatile installation. It offers advantages over centrifugal pumps in maintaining flow against high backpressure and handling shear-sensitive fluids without degradation. Drawbacks may include higher initial cost and the need for regular maintenance on seals and gears to prevent wear. This model, with 2-1/2" NPT ports, is constructed from durable cast iron for corrosion resistance in non-aggressive environments. Based on image analysis, the unit appears used with some internal wear visible on gears and ports, but the exterior paint is intact, suggesting it has been well-maintained. No parent/child assets like motors or controllers are attached. Suitable for applications requiring flow rates up to 190 GPM, it excels in reliability and longevity compared to similar Viking models like the KK series by offering higher capacity in a compact footprint.
