Aluminium central case featuring intermediate stages that form the diffusers and return channels, all assembled using tie rods for optimal durability. Aluminium suction and pressure heads are equipped with labyrinth seals on the shaft to ensure tight sealing. The rotor consists of aluminium airfoil impellers, which are securely coupled to a special steel shaft and balanced statically and dynamically for superior performance. The centrifugal impellers are mounted and coupled to the special steel shaft to maintain high efficiency. The bearings (both ball and roller) are housed in cast iron supports with ring seals, while the lubrication system automatically eliminates excess grease for easy maintenance. The transmission system is driven by belts and pulleys, with a belt stretcher mounted on the motor base to ensure consistent performance. A safety casing made of steel wire mesh is installed according to accident-prevention regulations on the motor base, providing enhanced protection. Upon request, the equipment can be manufactured in ATEX version, suitable for zone 1 /21 areas.
