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. 

Viking Pump Canada has been serving customers across the Canadian provinces for over 100 years. First opened in 1924 as an additional manufacturing center for US-based Viking Pump, Viking Pump Canada has developed into an important source of positive displacement pump expertise.

Through the years, Viking Pump Canada has had different ownership - but was ultimately reacquired by Viking Pump in 1992. Now with a strong focus on high quality distribution and service, Viking Pump Canada is accelerating growth for the entire Viking Pump business.

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.

Welcome, in this video we will guide you through the conversion from packing to Viking Pump’s O-Pro® Guard seal in pumps with the U-Plus™ bracket. This video applies to these pump models… 
Before you begin, please consult the appropriate technical service manual for safety information. A copy of the latest revision can be found on our website at vikingpump.com. 
To begin, remove the stainless-steel window guards from the bracket. 
Next, bend up the tang of the lock washer. 
Place a brass or hardwood bar into the port opening to keep the pump from turning. 

Let's start in Utah. Soaps and detergents are viscous and corrosive - making them perfect applications for Viking pumps. These include dishwasher detergent, laundry detergent, and hand soaps just to name a few. Many are liquids, but some are powder slurries which are then dried into powder or compressed into tablets for easier handling.
