LS Split Case

Overview

Overview

The Grundfos LS long-coupled, horizontal split-case pump offers increased pump performance and system efficiency. This double suction, single-stage, non-self-priming, centrifugal volute pump is designed especially for water utility applications and manufactured to the highest Grundfos quality standards. With a wide efficiency range and very low NPSHr, safe and economic operation is ensured, even when the actual flow deviates from the designed duty point.

LS pumps have a very high efficiency, not only at the rated flow but also within a wide flow range. The pump retains high efficiency even when the actual flow deviates by +/-20 % of rated flow. The feature enables the system to operate at high efficiency when pumps have to operate in parallel, which fits precisely the specific application at the pumping station, variable duty points and wide demands for flow range.

Grundfos LS pumps are in-line design with a radial suction port and radial discharge port. The flanges are in accordance with DIN standard. Pump performance is in accordance with ISO9906 G2. The compensated double-volute design virtually eliminates radial forces on the shaft and ensures smooth performance throughout the entire operating range. NPSHr for LS pumps at rated point is about 2m-5m and this fits most customer demands. In addition, Grundfos provides customised solutions for special requirements.
