Design Features :
- Balanced mechanical seal replaceable with out need for pump disassembling (for 10-15-22SV>=5,5kW, 33-46-66-92-125SV).
- “O” Ring seat design to allow for simple outer sleeve dis-assembly.
- Floating for self alignment replaceable diffuser wear ring (PPS Glass filled tecnopolymer to withstand chemically corrosive, mechanically aggressive and high temperature liquids).
- Reduced impeller axial thrust for longer standard motor bearing life (17,500h).
- Hard Material Intermediate bush bearing (Tungsten Carbide/Silicon Carbide) to improve life and ability to withstand heavy duty applications, like boiler feeding.
- High temperature seal option (180°C max) with low NPSH design, high pressure design (up to 40 Bar), and passivated & electro-polished versions are available upon request.
