Full Description

The Lowara LNTSX 50-390/40/204CS4 is a single-stage in-line centrifugal pump from the e-LNT range, a close-coupled in-line twin unit with two pumps. The twin-head design puts two pumps in one unit for duty/standby or parallel running. Its integrated variable-speed drive holds constant pressure while cutting energy use. Built for high flow rates in water supply, HVAC, cooling and industrial transfer, with a cast-iron casing, flanged connections and back pull-out servicing.

FAQs

What does the size code mean?

The first number is the discharge bore (e.g. 32 = DN32) and the second is the nominal impeller diameter in mm.

What’s the difference between e-LNE and e-LNT?

Both are close-coupled in-line pumps. e-LNE is a single pump; e-LNT is the in-line twin version — two pumps in one in-line unit for duty/standby or higher combined flow.

Can you confirm the duty point?

Send us your flow and head and we’ll confirm the exact model, impeller trim and motor.
