Vertical multi-stage centrifugal pump with integrated frequency converter. The pump materials in contact with the liquid are made of high-grade stainless steel (EN 1.4401).

CRNE 95-1-1 NV-P-A-V-HQQV 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 high-grade stainless steel. The Grundfos 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 PJE (Victaulic®) coupling. 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 is at the IE5 level. The junction box of the motor 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 the optimal operating state according to environmental conditions.
