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?

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. 

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.

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.
