Stork

The shaft seal is an essential part of our pumps. In the past, Stork Pumps often used compression gland packing and mechanical seals.

As recently as 2018, we converted a compression gland packing into a water-lubricated Liquidyne seal for a pumping station pump. This involved a Stork pump from 1969 equipped with a grease-lubricated compression gland packing. The Water Board (Waterschap) prescribed a water-lubricated lip seal, in part because of its target to eliminate the use of grease in surface water. As a pump manufacturer, we always carefully weigh up our options. We have chosen a pump shaft seal from Lagersmit, partially because of our positive previous experiences with the quality of products delivered, the service offered, and options for joint, customer-specific engineered solutions.

Adjustments have been made to the pump parts, and the Liquidyne® seal – delivered on time – has been installed. The pump, complete with the new Liquidyne seal, was then successfully commissioned and tested in the pumping station.
