Viking Pump's GB-425 Series™ is a robust and rebuildable external gear pump that is specifically designed for pipeline injection. 

Viking Pump is proud to bring you the new GB-425 Series™ pipeline injection pump. This robust, rebuildable external gear pump is specifically designed to handle the pressures, flow requirements, and abrasives that make crude oil pipeline injection one of the the most difficult applications.

Viking Pump has been leading the way in critical application pumps for over 110 years - and one of the most difficult - yet essential - applications is crude oil pipeline injection. We are proud to introduce the new GB-425 Series™.

In 2017, Viking Pump came on the pipeline injection scene with the GP-425 Series™ external gear pump - specifically designed for the rigorous pressures and flow rates required - and took the oil and gas industry by storm.

But we never stopped researching…

...never stopped designing…

...never stopped testing...

Viking Pump has evolved their flagship products. These are stainless steel pumps like you've never seen before. Modularity and customization are at the core of these products.

The new U-Plus™ bracket utilizes any of Viking Pump's cartridge or component mechanical seals, packing, and Viking Pump's own O-Pro® seals.
