Welcome, in this quick tip video we will guide you through the installation of a stuffing box component mechanical seal in Viking Pump’s with the U-Plus™ bracket. First, place the seal collar onto the shaft with the stepped side facing the end of the shaft. Insert a hex head wrench into the seal access hole and into a set screw to hold the seal collar in place. Install the seal installation sleeve with the taper toward the end of the shaft. Lubricate the shaft and inside of the rotary member of the seal.

Mechanical seals are extremely common in the pumping industry - and come in a wide range of materials and options. In its simplest form, a single component mechanical seal has two faces that contact and create a seal. These seal faces are lapped to a smooth, high quality finish. One face rotates with the pump shaft - while the other is held stationary in the pump housing. Once a small amount of process liquid reaches the seal faces, a hydrodynamic liquid film is created - this is what forms the seal and lubricates the faces.
