How it works
The Liquidyne 2-Stage seals the pump and uses the (cooling) water from the pump to lubricate and cool the seal. This water flow also enables the Condition Monitoring feature.
Liquidyne seals may consist of four types of modules
- fulfilling a sealing,
- a pressure reducing,
- a dirt retaining and
- a vacuum function.
What makes the Liquidyne special is the condition monitoring function.
More about Condition Monitoring
This function works through the water lubrication. The water lubricated Liquidyne lip seals run over a partially grooved bush placed over the pump shaft. The helical shape of the grooves and the peripheral velocity of the bush create water flow between the grooves and the lip seal.
Over time, the grooves on the bush gradually wear down. Less water is transported over the bush and the amount of water leaving the drain decreases. When the drain flow is at 20% of the initial flow, maintenance is required. By plotting this decrease in drain flow, you can plan maintenance more efficiently, optimize Mean Time Between Maintenance, reduce costs and prevent sudden pump failure.

“Thanks to the robustness of the Liquidyne seal, we hardly need to contact Lagersmit. However, if we do need to call them, we can rely on dedicated and solution-oriented people that will help us to take the right action. This works brilliantly!”
“There was a very positive interaction between our company and Lagersmit during our cooperation. Thank you for this customer experience.”
“The Liquidyne seal is robust and can stand a good deal. The big advantage is that the extent to which a seal is worn down is measurable. This enables us to plan maintenance and run our plant to a controlled stop rather than have an emergency shut down.”
