The FPS 6″ SR Series water pumps were designed specifically for municipal and industrial applications where high grade stainless steel is required. These pumps contain stainless steel impellers, a thick solid stainless steel shell to maintain alignment and heavy investment cast suction and discharge brackets. Designed to operate efficiently with Franklin Electric submersible motors, the FPS SR Series all stainless steel pump is equipped to handle the most demanding conditions.
Features
- 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
