E-pumps

Denmark-based Grundfos manufactures E-pumps that save energy and increase comfort. These are used in pressure boosting systems, hot or cold liquid circulation and for water supply. These pumps are based on the dry-running principle, lending themselves to applications other than circulation in heating installations. CRE, CRNE and CHIE are used for water supply and pressure boosting. The TPE series 2000 and LM(D)E, LP(D)E and TPE(D) are used for circulation in heating/cooling installations.The E-pumps range comprises pumps for single or three-phase main connections. Pumps with motor sizes of up to 1.1 kW are based on single-phase Grundfos MGE motor with built-in PI controller and connections for external control signals. Pumps with motor sizes of 1.5 kW or more are combined with the new three-phase MGE motorsThese pumps are flexible that t it is possible to adapt it to any application. The power range is 0.37 to 1.1 kW and 1.5 to 5.5 kW for single and three phase pumps, respectively. The single-phase pump has operational relay contact and the power supply is 1x220-230 V +/- 10 percent. Fault relay contact is for three-phase pump with power supply 3x380-415 +/- 10 percent. The sensor input for both the phases is 0-20 mA or 4-20 mA and the set point input is 0-5 V or 0-10 V.
