Vertical pumps with frequency control
A vertical multistage centrifugal pump with suction and discharge nozzles located on the same level (the so-called "in-line"), which provides the possibility of installation in a horizontal single-pipe system. The pump head and base are made of cast iron - all other parts in contact with the pumped product are made of stainless steel. A cartridge shaft seal ensures high reliability, safe handling and easy service and access. The rotation is transmitted through a detachable coupling. Connection to the pipeline using oval flanges with internal thread Rp. The pump is equipped with an air-cooled synchronous permanent magnet electric motor. The electric motor includes a frequency converter and a PI controller in the terminal box. This ensures constant smooth control of the motor speed, as well as the ability to adjust the performance characteristics in accordance with the specified requirements. The combination of the efficiency of the electric motor with the
