Grundfos CRN20 pumps are vertical & horizontal 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 CRN20 pumps come with various pump sizes and various numbers of stages to provide the flow and the pressure required.
Grundfos CRN20 pumps are suitable for a variety of applications from pumping of DI & RO water to pumping of chemicals. The pumps are therefore used in a wide variety of pumping systems where the performance and material of the pump meet specific demands. The CRN pumps consist of two main components: the motor and the pump unit. The motor on a CRN pump is a heavy-duty Grundfos specified motor. The pump unit consists of optimized hydraulics, various types of connections, an outer sleeve, a top and various other parts. Grundfos CRN pumps are available in various material versions according to the pumped liquid.
