Dredge Seals

For centuries, water management – including dredging and land reclamation − has helped the Netherlands to stay above water. Nowadays, this dredging knowledge is being used worldwide. From the palm island in Dubai to the Panama Canal, Lagersmit is there. Whether it involves propeller shaft seals, pump or cutter shaft seals, you can rely on us.


Dredging companies use all kinds or types of water pumps and dredger pumps. Liquidyne® pump shaft seals play a crucial role in pumps used for a wide range of applications:

  • Trailing suction hopper dredgers
  • Cutter suction dredgers
  • Dredging & mining slurry pumps

You are paid for every cubic metre of dredging spoil and work with strict deadlines. Every day that your dredger pump is down and that costs money, the Lagersmit seals minimises this downtime. You want your dredger pump to run as long as possible. Dredger pumps often have to cope with severe shocks and vibrations, the wrong alignment and/or an abrasive medium. Our pump shaft seals are specially designed to withstand events such as these. Added to that, you can monitor the condition of the seal so that you know exactly how long you can continue dredging.

Besides a stable dredger pump, it is also important to keep your dredging vessel going. To make this possible, we supply our own Supreme® shaft seals.
Our Supreme seals deliver a plus to your dredger’s propulsion system. We believe a stern tube seal should deliver top performance, keep you going and offer you Peace of Mind.

As a manufacturer of (dredger) pumps, it is important that your pumps run for as long as possible. The Liquidyne was designed especially for the dredging industry and does exactly that. Incorporate the Liquidyne into your new equipment programme and increase the reliability and durability of your pump.
