Grundfos 97568435, CM5-G Series, Model CM 5-2
Product Overview
System downtime during the height of the growing season or a sudden pump failure in a high demand commercial application can lead to rapid turf degradation, lost nursery stock, and costly emergency service calls. When peak summer heat hits and water requirements are at their maximum, waiting weeks for a back-ordered pump isn't an option for your clients. Securing the Grundfos CM 5-2 now ensures your projects stay on schedule and your water delivery systems remain operational. Proactive procurement protects your reputation and prevents the logistical headaches caused by localized supply shortages or extended manufacturer lead times. Having this unit ready for immediate deployment means you can solve water pressure issues before they become catastrophic failures.
The Grundfos CM 5-2 offers a distinct technical advantage over lighter duty utility pumps by utilizing a compact, horizontal multistage design that maximizes pressure output without increasing the physical footprint. This unit is engineered for continuous duty, meaning fewer callbacks for overheating and a significantly longer service life compared to standard centrifugal models. By choosing a pump known for high efficiency and quiet operation, you reduce long term energy costs for your clients and minimize maintenance labor over the life of the system. Maintaining a stock of these reliable units allows your crew to provide immediate, professional solutions while your competitors are still waiting on shipping confirmations.

Installation Notes
Installation of the CM 5-2 requires standard plumbing tools and a firm, level mounting surface to prevent vibration transfer. Ensure that the suction line is airtight and sized correctly to prevent cavitation during peak flow. It is recommended to install a foot valve or check valve if the pump is located above the water source level. All electrical wiring must be performed by a qualified professional in accordance with local codes and manufacturer wiring diagrams. Verify that the motor voltage matches the onsite power supply before commissioning the system.
