Product Description
Grundfos CR, CRI and CRN pumps are vertical multistage centrifugal pumps. The in-line design enables the pump to be installed in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal plane and have the same pipe dimensions. This design provides a more compact pump design and pipework.
Grundfos CR pumps come with various pump sizes and various numbers of stages to provide the flow and the pressure required. CR pumps are designed for a variety of applications from the pumping of potable water to the pumping of chemicals. The pumps are therefore suitable for a wide diversity of pumping systems where the performance and material of the pump meet specific demands.
The CR pumps consist of two main components: the motor and the pump unit. The motor of CR pumps is a Grundfos motor designed to EN standards. The pump unit consists of optimized hydraulics, various types of connections, an outer sleeve, a pump head and various other parts.
Benefits of Grundfos Pump & Motor Assemblies
• Motor: The ML motors are remarkably quiet and highly efficient.
• Cartridge seal: The specially designed cartridge seal increases reliability, ensures safe handling and enables easy service and access.
• Connection Options: The Grundfos CR can be connected to any piping system.
• Dry-running sensor: The patented Grundfos LiqTec ™ system eliminates the risk of breakdowns due to dry running. If there is no liquid in the pump, the LiqTec will immediately stop it.
• High-performance hydraulics: Pump efficiency is maximized by state-of-the-art hydraulic design and carefully crafted production technology.
• Durable bearings: The CR bearings are remarkably long-lived thanks to hardwearing materials and a wide range of options for difficult liquids.
