Three versatile additions to the 2600 dewatering line take advantage of vortex hydraulics.

Sludge pumps can find themselves in some pretty tough situations. They might need to move sediment-filled water out of a mine or pump light slurry from a factory that makes kitchen tiles. At a fish farm, they might have to transport water containing a lot of salmon waste.

Flygt’s three new sludge pumps are up to the task. The pumps, additions to the company’s flagship 2600 dewatering line, can tackle solids without missing a beat.

“You never know what a pump will encounter,” says Peter Hansen, product manager for Flygt drainage pumps at Xylem. “With these new sludge models, our customers get highly versatile pumps that handle larger solids with ease.”

The sludge pumps – models 2620.281, 2630.280 and 2640.280 – have a range of 1.5 to 5.6 kW (2.4-8.9 hp, 60 hz). They’re built with the same drive units as the existing 2600-series models, but they have vortex hydraulics that allow the pumps to move sediments, sand and light slurry. You can even convert an existing 2600 drainage pump into a sludge pump simply by replacing the hydraulics with a sludge version.

The three new models also incorporate the latest enhancement in Flygt pumps: the terminal board. By sealing off the junction box from the motor, the terminal board prevents any water from passing between compartments. “In the event of unwanted water entry,” Hansen explains, “the terminal board limits damage and therefore reduces repair costs.”

Although the sludge pumps can be used in permanent installations such as those at municipal wastewater treatment plants, Hansen anticipates that the pumps will mainly be used for temporary jobs. “I believe every rental location will acquire these models,” he says. “They’re multi-purpose.” In light of Xylem’s recent acquisition of Godwin pumps, these pumps are one more reason the company has become the global leader in the dewatering rental business.
