The first pumps with a new type of propeller have been sent out into the world.

The propeller type is designed, developed and produced here at the factory in Ferritslev, Denmark and is milled out in one piece from a solid block and into a very accurate propeller. The former propellers have been casted in a mold.

"We are constantly working to adjust and optimize our pumps. Throughout the company's history, we have had our propellers casted from molds designed by ourselves, but  casted at a foundry .

With the latest technology and large CNC machines, it is now possible that we can mill the propellers here at the factory at the exact angles and dimensions to pump water in the most energy-efficient way. It requires a lot of development work, but is also really exciting, when we see the results," says owner Karsten Lykkegaard.

It is the 5th generation at the factory, Jeppe Lykkegaard, who is behind the engineering work in designing, drawing and developing the new propeller type.

Significantly more efficient

According to in-depth tests in our factory, the new type proves to be more energy efficient than the previous cast propellers.

This means that if a customer changes a the propeller of a pump from the former to the new type, they will either have a larger pumping capacity at the same energy consumption or the same capacity at a lower energy consumption.

And for pumps that run around the clock, this is can surely be seen on the operating account. Lykkegaard's pumps already have a reputation of being extremely energy efficient, but with the new techonology we can guarantee a lower energy consumption.

The strategy to do all phases of the propeller-making in-house, from design to manufacturing, also dramatically reduces the production time of new propellers. Previously we had to go through a long process of having a mold made at a subcontractor and then have it sent to the foundry. Get the propeller cast, have it sent back to be machined and only then test it. Now, the whole process is done in a one day. From design to end test.

Better for the working environment

Being able to mill the propellers in stead of having them casted into a form is also better for the working environment.  The casting process contains physical hard work and it is difficult to avoid dust and gasses from the liquid metal coming into the air that the workers breathe.



That is a much more controlled process with the advanced CNC-machines. So it is a kind of win win - the propeller and the pump gets more exact and has a higher efficiency - AND the working environment is improved.

All pumps which pump from 10 - 200 l/sec are now produced with the new milled propellers.
