Lowara Lowara e-NSC (NSCE, NSCS)
Single-stage end-suction centrifugal pumps from the Lowara e-NSC series, with discharge from DN 32 to DN 300 and head up to 154 m.
e-NSC is the Lowara series of horizontal end-suction centrifugal pumps with radial discharge, single-stage (NSC2 has two stages), in back pull-out construction: the impeller, adaptor and motor can be removed without disconnecting the pump casing from the pipework. The casing and impeller are in cast iron in the standard version, with other materials available up to duplex stainless steel. At 50 Hz the brochure indicates flow up to 640 m³/h in the 2-pole range and up to 1,900 m³/h in the 4-pole range, head up to 154 m (2 poles) and 100 m (4 poles), liquid temperature from -25 to +120 °C in the standard version and a nominal pressure of 16 bar (PN 12 for NSC2).
The letter after NSC shows the construction: NSCE has an extended motor shaft, NSCS a short shaft (stub shaft), NSCF is frame-mounted, and NSC2 has two impellers. The code continues with the discharge port diameter, the impeller diameter and the motor power: in 32-125/22, 32 is the DN, 125 the nominal impeller diameter in mm, and 22 the power of 2.2 kW × 10. For a quotation please send us the full code, a photo of the nameplate and, for a pump without a motor, the motor data; we check the variant in the Lowara brochure before sending the quotation.

Frequently asked questions
What is the difference between NSCE and NSCS?
The brochure describes two constructions: an extended motor shaft (NSCE) and a short shaft, for coupling with a standard electric motor (NSCS). Other letters in the code: F for frame mounting, C for frame with spacer coupling, 2 for two impellers, no letter for the version without a motor (bare shaft).
How do I read “65-200/150”?
The first number (65) is the nominal diameter of the discharge in mm, the second (200) the nominal diameter of the impeller in mm, and 150 is the motor power in kW × 10, that is 15 kW. On versions without a motor, the last part contains the letter D and the actual impeller diameter.
Can I replace an e-NSC pump with another?
The connections comply with EN 733 for the models indicated in the brochure, but replacement depends on flow, head, liquid, seal and motor. You can send us the full code and a photo of the nameplate; we check the fit in the Lowara documentation.
Other Lowara series
The model list in the brochure has availability columns by construction (NSCE, NSCS, NSCF, NSCC) and by number of poles; for your exact code we confirm availability from the brochure table. Curves, dimensions and weights are read from the brochure per model.
