Grundfos Cme 25-2 High-Efficiency Water Pump for Industrial Use

Grundfos CME 25-2 A-R-I-E-AQQE S-A-D-N
A compact and highly reliable horizontal multi-stage end-suction centrifugal pump with an axial suction port and a radial exhaust port. The material of the pump body in contact with the liquid is stainless steel. The mechanical shaft seal is a specially designed unbalanced O-ring seal. The pipe connection is achieved through internal Whitworth pipe threads (Rp (ISO 7/1)). A 3-phase asynchronous motor with a cooling fan and a mounting bracket is installed on the water pump. According to the IEC 60034-30-2 standard, the energy efficiency of this motor is of IE5 level. The motor's junction box contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the water pump to be adjusted to its optimal operating state according to environmental conditions. The operation panel on the motor junction box can not only set the water pump to "minimum" or "maximum" operating intensity or "stop", but also set the required set values. The Grundfos Eye indicator on the operation panel can display the status of the pump:

"Power On": The motor is running (rotating green indicator light) or not running (steady green indicator light).
"Warning": The motor is still running (rotating yellow indicator light) or has stopped (steady yellow indicator light).
"Alarm": The motor has stopped (flashing red indicator light).
Communication with the pump can be carried out via the Grundfos GO Remote (accessory). The remote control can be used for further settings and to read certain parameters, such as "actual value", "speed", "input power", and "total power consumption". The terminal blocks for these connections are installed in the internal junction box.
