Challenge

Within a demanding application in a plastic recycling plant, KSB’s KWP pumps failed after barely six months of service. Due to the application’s arduous nature and the short-coupled pump’s construction, the mechanical seals and motors failed within this short period. Due to the high recurring repair costs associated with these pumps, and the risk of downtime, it was evident that a durable and reliable alternative had to be found. Since Vaikon already had a series of pumps running successfully within other processes in the plant, the customer came to us for a solution.

Solution

Although the existing pumps have their use in clean water applications, they are unfortunately not suitable for heavier applications like this one. As an alternative, the client followed our advice to replace them with Schegler Vigor pumps. These
heavy-duty slurry pumps have a significantly higher shaft stiffness and a more robust construction overall. Vigor’s high wear resistance, in combination with the expeller sealing, and its proven track record, convinced the customer to go with this alternative, despite the slightly higher purchase price. All Vigor pumps were delivered to the customer quickly and directly from our own stock.
