To begin, bend up the tang of the lock washer. Place a brass or hardwood bar into the port opening to keep the pump from turning. Loosen and remove the locknut. Remove and discard the lock washer. Loosen the bearing housing set screws. Loosen and remove the bearing housing. Remove the bearing spacer collar. The collar may have come out the bearing housing. Remove the half round rings. Remove the stainless steel window guards from the bracket. Loosen the set screws on the seal sleeve to free the sleeve from the shaft. Loosen and remove the two nuts holding the seal gland to the pump.

Welcome, in this video quick tip video we will guide you through the installation of Viking Pump’s O-Pro® Guard seal into a pump with the U-Plus™ bracket. 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. Before installing the new seal, ensure the shaft is free of any debris or wear. Any burrs can damage o-rings upon installation. You can now prepare the O-Pro® Guard seal for installation. First, install the three set screws into the sleeve.

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. 

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…

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.
