FEATURES of 1, 3, 5, 10, 15 & 22SV SERIES OPTIONS

  • »  Vertical multistage centrifugal pump. All metal parts in contact with the pumped liquid are made of stainless steel
  • »  Reduced axial thrusts enable the use of standard motors that are easily found in the market. The SM ? 0,75kW and PLM surface motors have efficiency values that fall within the range normally referred to as efficiency class IE2
  • »  Seal housing chamber designed to prevent the accumulation of air in the critical area next to the mechanical seal
  • »  Mechanical seal according to EN 12756 (ex DIN 24960) andISO3069for1,3,5SVand10,15,22SV(?4kW) series
  • »  Easy maintenance. No special tools required for assembly or disassembly
  • »  With round flanges that can be coupled to counter-flanges, according to EN 1092FEATURES of 33, 46, 66, 92 & 125SV SERIES
    • »  Version G: vertical multistage centrifugal pump with impellers, diffusers and outer sleeve made entirely of stainless steel, and with pump casing and motor adaptor made of cast iron
    • »  Innovative axial load compensation system on pumps with higher head. This ensures reduced axial thrusts and enables the use of standard motors that are easily found in the market
    • »  Seal housing chamber designed to prevent the accumulation of air in the critical area next to the mechanical seal
    • »  The pumps for G and N versions are certified for drinking water use (as per AS/NZS 4020)
    • »  Standard version for temperatures ranging from -30° to +120°C
    • »  Pump body fitted with couplings for installing pressure gauges on both suction and delivery flanges
    • »  In-line ports with round flanges that can be coupled to counter-flanges, in compliance with EN 1092
    • »  Mechanical sturdiness and easy maintenance. No special tools required for assembly or disassembly
