Grundfos 97568303, CM3-G Series
Product Overview
System shutdowns during peak irrigation demands can lead to catastrophic turf damage and expensive crop loss; failures that contractors cannot afford when high summer temperatures arrive. Waiting for a replacement pump once a system has already failed creates unnecessary pressure from clients and puts your reputation at risk. Global supply chain fluctuations often mean long lead times for high performance motor units; leaving your projects stalled while you wait for backordered components. By securing your equipment now, you ensure your crews remain on schedule and your clients' landscapes remain viable through the toughest parts of the growing season.
The Grundfos CM3-G Series offers a significant technical advantage over standard residential grade pumps through its modular design and industrial build quality. This horizontal multistage centrifugal pump is engineered for compactness and reliability, which reduces the labor required for retrofitting into existing tight mechanical spaces. The high grade stainless steel construction minimizes long term maintenance costs by resisting corrosion and internal wear better than cast iron alternatives. Maintaining a stock of these reliable units provides your business with a competitive edge, as you can offer immediate, high quality solutions when inferior systems fail under pressure.

Installation Notes
Ensure that the pump is installed on a level, solid foundation and that the suction line is airtight to prevent cavitation. We recommend installing a foot valve for suction lift applications and a check valve on the discharge side to protect the pump from water hammer. All electrical connections must be performed by a qualified technician according to local codes, and the pump should never be run dry. Use pipe dope or thread tape on NPT connections to secure a leak free seal during the initial commissioning phase.
