CRNE 45-2-2 A-F-A-E-HQQE Vertical, multi-stage centrifugal pump unit with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in high-grade Stainless Steel. A cartridge shaft seal ensures high reliability, safe handling, and straightforward access and service. Power transmission is via a rigid split coupling. Pipe connection is via DIN flanges. The pump is equipped with a 3-phase, fan-cooled, permanent-magnet, synchronous motor. The motor efficiency is classified as IE5 in accordance with IEC 60034-30-2. 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. An operating panel on the motor terminal box enables setting of required setpoint as well as setting of pump to "Min." or "Max." operation or to "Stop". The Grundfos Eye indicator on the operating panel provides visual indication of pump status:
- "Alarm": Motor has stopped (flashing red indicator lights)
- "Warning": Motor is still running (rotating yellow indicator lights) or has stopped (permanently yellow indicator lights)
- "Power on": Motor is running (rotating green indicator lights) or not running (permanently green indicator lights)

Communication with the pump is possible by means of Grundfos GO Remote (accessory). The remote control enables further settings as well as reading out of a number of parameters such as "Actual value", "Speed", "Power input" and total "Power consumption".
