The Lowara NSCE 40-125/05/S45RCS4 (101843230) is an end-suction centrifugal pump from the Lowara e-NSC range, close-coupled (extended shaft), with a cast iron casing, stainless steel impeller and a 0.55 kW 4-pole motor (~1450 rpm) for a 400 V three-phase supply. It delivers up to 28.8 m³/h (8 l/s) and up to 6.5 m of head.

The impeller is keyed directly onto the extended motor shaft for a compact unit. Back pull-out design lets the motor, adapter and impeller come out without disturbing the pipework. DN40 flanged discharge with EN 733 connection dimensions and a silicon carbide/carbon/EPDM mechanical seal, for clean water in heating, cooling, water supply and industrial process systems.

FAQs

How much will it pump?

Up to 28.8 m³/h (8 l/s) with 3.7 m of head still available, and up to 6.5 m of head at zero flow. Choose the pump so your duty point sits near the middle of the curve.

What power supply does it need?

3 × 220–240 / 380–415 V three-phase, 50 Hz.

Can it pump hot water?

Yes — with the standard seal it handles −25 to +120°C, rated 16 bar up to 90°C and 10 bar at 120°C.

Are counter-flanges included?

No — counter-flanges, bolts and gaskets are ordered separately. Ask us and we’ll add the right set.

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.
