Well suited for use in cities

“One of our 10 vacuum tanker trucks runs regularly for the Danish construction group Aarsleff’s division that carries out cured-in-place pipe lining, a technique used to repair leaky sewers. Here, we flush and empty the sewers to remove sludge and waste before the cured-in-place lining is led through. This work is often done in cities, where the Samson pumps come into their own. Compared to rotary vane pumps, which make far too much noise while running, Samson’s liquid ring pumps are practically noiseless. This is, of course, a big advantage for the workers operating the pumps, but also for the people who live and work in the surrounding area.

“The environment and working area also benefit when we use Samson pumps. Because the pumps are water-based, they only emit harmless steam, which evaporates quickly and doesn’t bother the operator. Oil-based rotary vane pumps, on the other hand, emit oil fumes that cause problems for both the operator and the surrounding environment. If the vacuum tanker truck is parked next to a building, the oil fumes can stain the wall. If a rotary vane pump has a downward-facing exhaust, the oil fumes settle like a film that looks awful and can damage the asphalt. We can avoid this type of trouble and damage by using liquid ring pumps from Samson,” Ulrik explains

Pump from 1996 still running

Djursland Kloakservice ApS purchased its first Samson pump in 1996, and it is still running today, just not in Djursland. The company has a policy of replacing its vacuum tanker trucks after around 12 years of ‘”service.” The vacuum tanker was thus sold to a colleague who still uses the vehicle and the incredibly durable Samson pump on a daily basis.

A few years ago, Ulrik began offering dry matter vacuuming, such as the removal of ash from combustion plants. As of yet, he is not sure if there will be enough work to purchase a dedicated – and expensive – dry matter vacuum. He therefore decided initially to fit a vacuum tanker truck with two Samson pumps. This proved to be an effective solution, and a high number of orders quickly came in – so many, in fact, that after a couple of years there was a basis for investing in a costly mammoth vacuum that is designed on a completely different pumping principle than Samson’s liquid ring pumps.

“Today we’re doing a lot of work with dry matter suction, which has become an important business area for us. And it was the strong and effective pumps from Samson that made it possible for us to move into this area,” Ulrik notes.
