Grundfos 96806913, CM3-G Series, Model CM 3-2

Product Overview

System downtime during the heat of the peak growing season is a liability no contractor can afford. When a booster pump fails, the resulting loss of pressure leads to uneven water distribution, parched turf, and compromised crop yields that can sour client relationships instantly. With global supply chains remains unpredictable, waiting for a replacement pump mid-season often results in weeks of back-orders while your project deadlines slip. Stocking the Grundfos CM3-G Series now provides the critical insurance your operation needs to ensure irrigation cycles remain consistent and your reputation for reliability stays intact through the most demanding summer months.

The Grundfos CM 3-2 distinguishes itself from standard centrifugal pumps through its compact, horizontal multistage design and superior hydraulic efficiency. While lower-grade alternatives often suffer from cavitation or premature motor failure under continuous duty, the CM series is engineered for modular flexibility and quiet operation. This design allows your crews to install high-performance pressure boosting in tight footprints where traditional pumps won't fit. By choosing a pump with integrated thermal protection and high-grade stainless steel components, you reduce the frequency of unpaid warranty callbacks and lower the long-term total cost of ownership for your clients.

Product Specifications

Available Models & Sizes

The CM3-G series is available in several configurations including various stage counts to meet specific head pressure requirements. While the CM 3-2 serves standard boosting needs, larger CM5 and CM10 models are available for higher volume demands. Please contact our technical sales team for full configuration options, specific motor voltages, or updated bulk pricing for large scale projects.

Key Features

• Compact modular footprint allows for seamless integration into existing skid packages or tight mechanical rooms.

• Advanced shaft seal materials prevent leaks and extend the service life between scheduled maintenance intervals.
• Low-noise operation ensures compliance in residential areas and noise-sensitive commercial environments.
• Designed for continuous duty cycles, maintaining stable pressure even during extended irrigation windows.
• Optimized motor efficiency reduces electrical consumption for your clients without sacrificing flow performance.

Common Applications

• Commercial landscape irrigation for retail centers and office complexes.
• Residential lawn and garden systems requiring consistent pressure boosting.
• Agricultural and crop irrigation for small-scale specialty farms.
• Sports turf and golf course maintenance for localized green or tee box irrigation.
• Greenhouse and nursery operations requiring precise water delivery.
• Municipal parks and public spaces utilizing reclaimed water systems.

Installation Notes

Always verify the electrical supply matches the motor nameplate before wiring. The CM 3-2 requires a stable foundation to prevent vibration and should be installed with isolation valves on both the suction and discharge sides to facilitate future servicing. Ensure the pump is fully primed and the system is vented of air before initial startup to prevent dry running, which can damage the internal seals. All installations should adhere to local plumbing and electrical codes to maintain manufacturer warranty coverage.
