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

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.

So your pump is making noise due to cavitation. Now what?

Join Viking Pump's Chad Wunderlich as he describes the multiple ways to address and solve for a cavitating pump. 


So just to recap: a cavitating pump is one that is exhibiting noise, loss of capacity, and if left unchecked can lead to localized pitting of the pump internals. The cause is excessive vacuum at the pump inlet. So what's the fix? 


For most systems, it starts with atmospheric pressure - but you can't move your entire facility to sea level. So what CAN you fix?

What causes pumps to cavitate? And why is my pump so LOUD?

In this Pump Report, Chad covers the causes and symptoms of positive displacement pump cavitation.


Hi, I'm Chad Wunderlich with Viking Pump. In a previous video we discussed the priming capability of positive displacement pumps, like this gear pump. This is due, in part, to the pump's ability to develop vacuum...but what happens if that vacuum gets too high? 


Today we're going to talk about cavitation. You're watching the Pump Report. 

Slowing Down Your Pump's Motor with a Variable Frequency Drive (VFD)

In a positive displacement pump, each rotation of the shaft and gears carries a fixed volume of liquid from the supply tank to the downstream piping. When paired with an AC induction motor, speed and flow are very consistent. But what if you want to CHANGE the flow? In this episode of the Pump Report, Chad discusses controlling your positive displacement pump's motor with a variable frequency drive - or VFD.

Understanding Internal Gear Pumps: How They Work and Their Benefits

Search Description

Discover how internal gear pumps work, their key features, and their advantages across various industries. Learn why they're the preferred choice for fluid handling.

Introduction to Internal Gear Pumps

Internal gear pumps are a fascinating invention that has stood the test of time. Created by Viking Pump over a century ago, they remain one of the company's most recognized products. These pumps are a type of rotary positive displacement pump, which means they move fluid by utilizing the rotary motion of their components.

How do you connect a pump to a motor? Here are FOUR common drive types

In a previous Pump Report Chad discussed the motors used to power pumps. But how do you connect a pump to that motor? And what if you want to run the pump slower than motor speed? In this episode Chad talks about drives and their related equipment. 

The term “drive” is used to describe the ancillary equipment used to mount and power a pump. This includes the motor, which we’d already discussed, but can also include a baseplate, coupling, guard, reducer, and more.

Pressure Relief Valves: Critical to Pump and System Safety and Reliability

Search Description

A key advantage of rotary positive displacement pumps is providing consistent flow regardless of changes in liquid viscosity or differential pressure. But should a downstream blockage occur, pressure will rapidly build and may exceed the rating of the pump, drive equipment, system, or any combination thereof, with the potential for damage and unplanned downtime. For this reason, overpressure protection must be used, and pressure relief valves are the most commonly used form of overpressure protection for rotary positive displacement pumps.
