Fabricated stainless steel impellers and diffusers for corrosion resistance
Heavy duty stainless steel structure for improved stiffness and ensuring the permanent alignment of all components and thus increased run time and trouble-free operation
PTFE floating neck ring, ceramic guide journal sleeve (tungsten-carbide on request) and Nitrile rubber fluted bearing to ensure durability against wear for long-lasting constant performances and product reliability
Compact, reliable and suited to operate in horizontal position
Built-in check valve to protect the pump against water hummer risk
Radial models with double reinforcement rings and mix-flow models longer than 3 m are equipped with tungsten-carbide (widia) upper journal sleeve and with an intermediate tungsten-carbide (widia) journal sleeve plus special intermediate split cone nut
The hydraulic design is such to enhance the overall efficiency thus reducing energy consumption and making the pumping systems more cost effective
