Multi-stage centrifugal pump with an integrated frequency converter. The material of the pump body in contact with the liquid is stainless steel (EN 1.4301).

CRIE 20-6 V-FGJ-A-E-HQQE Vertical multi-stage centrifugal pump with the inlet and outlet on the same horizontal plane (in-line). The material of the pump body in contact with the liquid is stainless steel. The cylindrical shaft seal can improve the reliability of the machine and the safety of operation, making maintenance more convenient. Electrical energy is transmitted through a split coupling. The connection of the pipeline is achieved through a combined flange of DIN - ANSI - JIS. An asynchronous motor with a cooling fan and feet, and of three - phase type, is installed on the water pump. According to the IEC 60034 - 30 - 2 standard, the energy efficiency of this motor belongs to the IE5 level. The junction box of the motor contains a frequency converter and a PI controller. This allows the system to continuously adjust the motor speed, enabling the water pump to adjust to the 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 fixed values. The Grundfos Eye indicator light 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 - on green indicator light). "Warning": The motor is still running (rotating yellow indicator light) or has stopped (steady - on yellow indicator light). "Alarm": The motor has stopped (flashing red indicator light).

Communication with the pump can be achieved through the Grundfos GO Remote (accessory). The remote control can be used for further settings and to read certain parameters, such as the "actual value", "speed", "input power" and "total power consumption". The junction box is equipped with a large number of input and output interfaces, enabling the motor to be applied in advanced scenarios that require a relatively large number of inputs and outputs.
