We’ve been making seals ever since we launched the world’s first submersible pump in 1948. Because the sealing system is the heart of a submersible, we make no compromises. Not only do we develop all seals ourselves, but we’ve even kept manufacturing strictly in-house.
The right stuff
Most materials used for the face of the seal offer either good corrosion resistance or high durability. Working together with metallurgists, we have developed a unique tungsten carbide alloy that offers both.
Facing aggressive media
As a complement to tungsten carbide, we offer silicon carbide seal faces for seawater and media with a low pH.
The art of making unflat seals
At Flygt, we actually build a slight concavity into our seals. Why? As the seals get warm during operation they straighten out for a flatter seal face.
Keeping their cool
Flygt seals are designed so that heat is quickly and efficiently transferred to the surrounding material. This keeps seals cool even when they are running dry.
The spin doctor
Spin-Out™ is a patented design that harnesses the centrifugal force of the shaft to spin abrasive particles out of the seal cavity. The result is less wear on the seal and reduced risk of clogging.
Plug & play & play & play
Plug-In™ is a cartridge seal that offers fool-proof mounting, eliminating the risk of human error. Because the inner and outer seals are factory-assembled as a unit, the seal faces are protected from dirt, solids and long fibres that could cause leakage.
