Design Features
- Balanced mechanical seal replaceable without 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 technopolymer 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.
Further unique features of the e-SV include the integration of performance diagnostic devices such as the i-Alert™ vibration monitor and the Dry Run sensor. The i-Alert™ and the Dry Run sensor are available as an accessory for all models.
