MODEL#: CR5-4
1-1/2HP, 69 Max PSI, Oval-Flanges, EPDM O-ring
Cast Iron/304 Stainless Steel, 1-1/4 NPT

Most efficient at flow rate from 13 gpm to 45 gpm
and pressure from 30 psi to 65 psi (approximate numbers).

CR pumps are suitable for a variety of applications frompumping of potable water to pumping of chemicals. Thepumps are therefore used in a wide variety of pumpingsystems where the performance and material of thepump meet specific demands.

The CR pumps consist of two main components: themotor and the pump unit. The motor on a CR pump is aheavy-duty Grundfos specified motor.The pump unit consists of optimized hydraulics, varioustypes of connections, an outer sleeve, a top and variousother parts.

The in-line design enables the pump to beinstalled in a horizontal one-pipe system where thesuction and discharge ports are in the same horizontalplane and have the same pipe dimensions. This designprovides a more compact pump design and pipework.Grundfos CR pumps come with various pump sizes andvarious numbers of stages to provide the flow and thepressure required.
