What a WATER Barometer Teaches Us About Pumps

This is a gear pump, a type of rotary positive displacement pump. Its tight-fitting clearances allow it to evacuate air in the suction line to prime the pump. And once primed, it's capable of pulling even higher vacuums. This ability to self-prime is key in applications like unloading drums, totes, rail cars, and barges. But as good as this pump is at pulling the liquid in, it's always going to be limited and not based on the pump. It's based on an invisible force pushing the liquid in from the outside, and that's atmospheric pressure.

How REVERSIBLE Internal Gear Pumps Work

Hi! I’m Chad Wunderlich with Viking Pump and this is an internal gear pump. With each rotation of the gears, a set volume of liquid is moved from the inlet to the outlet. And if I were to reverse the direction of rotation, I reverse the direction of flow. Now this isn’t unique to internal gear pumps, other rotary pumps like external gear, lobe, and hose pumps exhibit this same behavior. But did you know it’s possible to make this internal gear pump deliver flow in just one direction, independent of the direction of rotation?

Viking Pump invented the internal gear pump in the early 20th century; but did you know that we carry various other pump technologies? Most of them are easily identifiable based on their shape. But one common mistake that we see is confusing a lobe pump and a circumferential piston pump. So what exactly are the differences and advantages of circumferential piston pump technology (CPP)?

Revolutionary to Evolutionary: A brief history of the Viking Pump® internal gear pump

Author / Byline
by Chad Wunderlich - Distributor Development Manager
Search Description

In the early 20th century industrial innovation was accelerating. And as Henry Ford developed his Model T and the Wright Brothers were unlocking the secrets to manned flight, a Danish immigrant named Jens Nielsen was working on an invention of his own. Nielsen’s internal gear pump was intended to be used to lift water from his quarry but soon others found uses for his pump and the Viking Pump® company was formed.
