DSL/NSL/ESL series - Inline centrifugal pump
DESMI DSL, NSL AND ESL vertical in-line centrifugal pumps. Vertical, space-saving in-line design that can be easily installed in existing piping systems
The DSL/NSL/ESL series have high efficiency, low NPSH requirements, are easy to install and have low maintenance costs. DSL/NSL/ESL series in-line centrifugal pumps are widely used in various applications and markets.
Easy installation and access for maintenance, monobloc design without alignment requirements - with or without ball bearings, or spacer coupling
NSL is a radial split, single-stage centrifugal pump in in-line design with connecting flanges according to international standards. The pumps can handle electric motors with different international flange dimensions.
The pump casing is equipped with a replaceable seal ring. The impeller has double-curved blades that ensure low NPSH values and high efficiency.
The bearing unit is equipped with heavy-duty ball bearings; the smaller models have permanently lubricated ball bearings and the larger models have double ball bearings with grease nipples.
Can be supplied with built-in vacuum pump for self-evacuating function.
Typical applications and fluids are water - with or without additives, seawater, thin oils, diesel, gasoline, chemicals. Excellent for fuel depots, cooling water/media, circulation systems, alcohols and solvents
