CR, CRI, CRN, CRE, CRIE, CRNE 4 Product data Introduction This data booklet deals with CR, CRI and CRN as well as CRE, CRIE and CRNE pumps. CR, CRI, CRN Fig. 1 CR, CRI and CRN pumps CR, CRI, 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...

Product data CR, CRI, CRN, CRE, CRIE, CRNE Pump The CR and CRE pump is a non-self-priming, vertical multistage centrifugal pump. The pumps are available with a Grundfos standard motor (CR pumps) or a frequency-controlled motor (CRE pumps). The pump consists of a base and a pump head. The chamber stack and the outer sleeve are secured between the pump head and the base by means of staybolts. The base has suction and discharge ports on the same level (in-line). All pumps are equipped with a maintenance-free mechanical shaft seal of the cartridge type. Fig. 3 CR pump CR pump with ANSI/NSF 61...

Product data CR, CRI, CRN, CRE, CRIE, CRNE 10 Terminal box positions As standard the terminal box is mounted on the suction side of the pump. Fig. 4 Terminal box positions Ambient temperature Ambient temperature: Maximum +104 °F. If the ambient temperature exceeds +104 °F or if the motor is located 3280 feet above sea level or higher, the motor output (P2) must be reduced due to the low cooling effect of the air. In such cases, it may be necessary to use a motor with a higher output. Fig. 5 Relationship between motor output (P2) and ambient temperature Viscosity The pumping of liquids with...

CR, CRI, CRN, CRE, CRIE, CRNE Product data for E-pumps Examples of E-pump applications CRE, CRIE and CRNE pumps are the ideal solution in a number of applications characterized by a need for variable flow at constant pressure. The pumps are suited for water supply systems and pressure boosting, but also industrial applications. Depending on the nature of the application, the pumps offer energy-savings, increased comfort or improved processing. E-pumps in the service of industry Industry uses a large number of pumps in many different applications. Demands on pumps in terms of pump...

CR, CRI, CRN, CRE, CRIE, CRNE 12 Control of E-pumps Control options of E-pumps Communication with CRE, CRIE, CRNE pumps is possible by means of • a central management system, • remote control (Grundfos R100) or • a control panel. The purpose of controlling an E-pump is to monitor and control the pressure, temperature, flow and liquid level of the system. Central management system Communication with the E-pump is possible even though the operator is not present near the E-pump. Communication is enabled by having connected the E-pump to a central management system allowing the operator to...
