The United Pumps model VP is a single stage, vertical, in-line bearing bracketed centrifugal pump, that is flexible and versatile enough to meet the requirements of a wide variety of pumping applications today. Commonly serving in oil refineries, petrochemical plants, and offshore environments, the United VP pump has proven itself to be a very reliable piece of equipment.
In 2015, Valero Refining in Port Arthur, TX decided to incorporate Isomag magnetic bearing seals on their VP pumps to add to it's already robust reputation. This batch of pumps went to a new unit using oil mist as the lubrication system. Isomag magnetic bearing isolators eliminate stray oil mist their liquid tight sealing faces. In addition to providing superior sealing and protection.
Since the installation, Valero Refining has reported that the stray oil mist issue has been alleviated and their pumps in the unit have cooler bearing housings.
