Grundfos CME3-4 A-S-A-E-AVBE

Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port and

radial discharge port. The shaft, impellers and chambers are made of stainless steel. 

The inlet and

discharge parts are made of cast iron. 

The mechanical shaft seal is a special designed, unbalanced

O-ring seal.

 Pipework connection is via internal NPT pipe threads.

The pump is fitted with a 1-phase, fan-cooled, permanent-magnet, synchronous motor. The motor

includes a frequency converter and PI controller in the motor terminal box. 

This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement. The combined motor and frequency converter efficiency

exceeds the super premium efficiency IE4 level defined for fixed-speed motors in IEC 60034-30-1
