Grundfos CM SP Horizontal Multistage Self-Priming Pumps with AQQE Silicon Carbide Seal

The Grundfos CM-SP Series is a compact and efficient range of horizontal multistage self-priming pumps, engineered for applications where priming reliability and corrosion resistance are essential. Built with a modular design and fully stainless steel wetted components, these pumps deliver long-lasting, quiet performance for both commercial and light industrial use.

Featuring a robust AQQE mechanical shaft seal with silicon carbide for enhanced durability, the CM-SP can achieve a suction lift of up to 4 metres, making it ideal for installations where the pump must draw water from below its inlet. The axial suction and radial discharge port configuration, combined with internal Whitworth pipe threads (Rp ISO 7/1), allows for easy integration into new or existing systems.

Each pump is powered by a single-phase IP55-rated foot-mounted asynchronous motor, ensuring smooth operation with minimal maintenance. The CM-SP range is well-suited for water transfer, pressure boosting, and systems where compact self-priming functionality is required.
