13 brand new – and large – hybrid pumps are being assembled and made ready for a major project in Northern Norway.

They are all of the type LMSALT 600. The pumps are to be part of a brand new fish farm that Cermaq Norway is building to farm salmon.

Since the pumps are to work in salt water, which is aggressive, they would quickly corrode if they were constructed as traditional steel pumps. Instead, the pump pipes are constructed of the corrosion-resistant HDPE material, while the shaft and propeller are made of the strong and acid-resistant duplex.

For smaller pumps, the T-bend can also be made of HDPE. However, the pumps here have a diameter of 600 millimeters and are therefore both large and heavy. Therefore, the T-bend is made of steel, which is surface-treated with a very strong composite that is resistant to salt water.

The first five pumps have just been shipped. The next five will be ready at the beginning of 2026. The last three will be designed slightly differently, so they will have a higher capacity. They will be ready in March 2026.
