Several customers return to Lykkegaard A/S because their electricity bills have become significantly lower after they have bought one or several pumps from Lykkegaard. In these months, more than ever, we experience our customers' concern for the energy consumption is larger than ever due to the global energy crisis. It is however, not the only reason why the awarenes of energy consumption is rising. We experience a growing interest for sustainability and general consciousness on consumption. 

More orders have come in from customers who buy a single or a few pumps to test whether it can be true that they use significantly less power in relation to the performance, than their previous pumps. Now they are returning to replace all their pumps and with that mission save huge sums on the electricity bill.

A French fish farm has bought 12 pumps on that account over the past year and a half. They first bought one pump in the spring of 2021. Then five more, which were delivered last summer. And now we have just sent the last six away, so they have received a total of 12 pumps.

"We find that customers are significantly more demanding for higher energy efficiency. And with good reason, because a lot is saved in the long term, especially with the rising energy prices we have nowadays," says Karsten Lykkegaard, who owns Lykkegaard Pumper A/S.

The pumps are optimized for the customer's needs

Lykkegaard specializes in producing pumps for draining low-lying areas and for the fishing industry. Many of the pumps work around the clock to either circulate and oxygenate water or to drain. Therefore, savings in energy consumption make a big difference on an annual basis.

At Lykkegaard A/S, each individual pump is designed and produced specifically for the customer's needs. In the calculations, it is designed to run at the best operating point – that is, where you use the least amount of energy to achieve the lifting height and performance that the customer needs.

All pumps from Lykkegaard are tested in Lykkegaard's own testing center before they are shipped to the customer. The customer receives a signed certificate that the pump meets the targets for water volume, lifting height and energy consumption.

Looking for details that can optimize energy even more

At Lykkegaard it has always been a goal to achieve energy-efficient pumps. Karsten Lykkegaard's grandfather developed pumps where the diameter of the pump pipe is increased at the outlet compared to the inlet, because it lowers the water speed and thus also the energy loss.

The pumps are still designed according to that technique – even though it is more complex to produce than if the pipes had had the same diameter.

In addition, the newest pumps are getting a new type of highly efficient propeller, which is milled rather than cast. The detailed accuracy means that the propeller uses less energy to move the same amount of water at the operating point.

"It is in our DNA to work with energy optimization and we have done it for generations. But with the increasing focus on climate, environment and especially the unruly energy prices we have nowadays, we find that more customers do not just see it as a positive, but a definite criterion,  when choosing new pumps," says Karsten Lykkegaard, who also promises that the company continue to develop and optimize the pumps.
