CR, CRI and CRN pumps are vertical multistage, centrifugal pumps. The in-line design of the pumps enables installation in a horizontal one-pipe system where the suction and discharge ports are in the same horizontal level and have the same pipe dimensions.
This design provides a more compact pump design and pipework. CR pumps are available in various sizes and various numbers of stages to deliver the flow and pressure required.
CR pumps are designed for a variety of applications ranging 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.
A CR pump consists of two main components: the motor and the pump unit. The motor is a Grundfos motor designed to EN standards. The pump unit consists of optimised hydraulics, various types of connections, a sleeve, a pump head and various other parts. CR pumps are available in various material versions according to the pumped liquid.
