e-SV vertical multistage pump in stainless steel

The Lowara e-SV vertical multistage pump is a highly reliable and technologically advanced multipurpose pump. It’s capable of satisfying the needs of a wide variety of users and many different construction designs are available. The e-SV range feature models in eleven sizes  with 1-3-5-10-15-22-33-46-66-92-125 m³/h nominal capacities.
All pumps ≥ 1.5kW are equipped with IE3 standard motors.

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 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 Dry Run sensor. The  i-Alert™ and the Dry Run sensor are available as an accessory for all models.

The e-SV is certified by WRAS, ACS and D.M. 174 for use with potable water.
