DSL
Vertical In-line Double Suction Centrifugal Pump DSL

The DSL pumps are high capacity pumps.
Up to 4000 m3/h, pressure up to 40 mLC
The DSL pumps are single-stage, double-suction, vertical, centrifugal pumps. The design of the suction side
provides for a perfect flow, and the inlet is placed in line
with the outlet. Add to this the advanced double-suction
impeller and the result is high efficiency and low NPSHvalues.
Application
Ballast and cooling water pumping are among the many
tasks that the DSL pumps solve to perfection. But also
district heating and power plants together with many
other industries will profit from using DSL pumps.
