Lowara NCSE 400v 1450rpm
Lowara NSC2 32-250/11A/P45RCS4 400v 101843871
- Established 1975
- Trusted by thousands of customers
The Lowara NSC2 32-250/11A/P45RCS4 (101843871) is a two-impeller end-suction centrifugal pump from the Lowara e-NSC range, close-coupled on an extended motor shaft, with a cast iron casing, stainless steel impellers and a 1.1 kW 4-pole motor (~1450 rpm) for a 400 V three-phase supply. It delivers up to 13 m³/h (3.6 l/s) and up to 18.7 m of head.
The two-stage NSC2 design gives higher head than a single-impeller pump of the same size. Back pull-out construction lets the motor, adapter and impellers come out without disturbing the pipework, and a silicon carbide/carbon/EPDM mechanical seal suits clean water in heating, cooling, water supply and process systems.

What are centrifugal pumps used for?
Centrifugal pumps use a rotating impeller to move liquids and are commonly used for water transfer, circulation and industrial processes.
How do I choose a centrifugal pump?
Compare the required flow rate, total head, liquid characteristics and electrical supply with each pump’s performance curve.
Are centrifugal pumps suitable for dirty water?
Some are designed for clean water only, while others handle solids or wastewater. Check the particular pump’s permitted liquid and solids specification.
