Welcome. In this Quick Tip video, we will show you how to modify and install the knockout style stainless steel window guards on a Viking Pump.
In order to accommodate grease zerks, drain lines, or other fittings window guards may need to be modified. To do this, first dry fit the window guard to identify which knockout section needs to be removed.
Wedge a flat screw driver into the knockout and rock the piece back and forth to fatigue the joints. Ensure to wear hand and eye protection.

Lip seals are a simple, economical, and compact sealing solution.
Their narrow profile makes them easy to fit into small pumps and tight spaces.
A lip seal consists of a flexible elastomeric lip held in a rigid housing. The lip seal is stationary — while the shaft rotates inside.
An inboard spring helps energize the lip — keeping it in constant contact with the rotating shaft, maintaining the seal.
An outboard lip — called a wiper — prevents contaminants in the outside environment from entering the pump.

What exactly are adhesives? And how do you pump them? Adhesives are substances, like cement or glue, that hold materials together by surface attachment. They are made from materials such as latex, silicones, and starch. Their viscosities range from water thin to extremely viscous. And some are shear sensitive. Adhesives are used in a number of different applications including: cardboard box manufacturing, plywood, paper bags, and industries like automotive and printing. So what's required to pump the various types of adhesives?

Welcome, in this video we will guide you through the conversion from packing to an O-Pro® Barrier seal in Viking 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, bend up the tang of the lock washer.

What are asphalt emulsions? And how do you pump them?
An asphalt emulsion is asphalt suspended in a mixture of water or other liquids. This makes applying the asphalt easier. Emulsions can be shear-sensitive and must be handled with care.
Asphalt emulsions are typically used in crack filling, coating roadways, or as a waterproofing substance.
So what's required to pump asphalt emulsions?
Shear sensitivity makes internal gear pumps ideal—their smooth, non-pulsating flow maintains the emulsion.

Welcome, in this video we will guide you through the replacement of O-Pro® Barrier seal o-rings in Viking 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, 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.
