Features of 1, 3, 5, 10, 15 & 22SV series

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 ≥ 0,75 kW 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) and ISO 3069 for 1, 3, 5SV and 10, 15, 22SV (≤ 4 kW) series

Easy maintenance. No special tools required for assembly or disassembly

With round flanges that can be coupled to counter-flanges, according to EN 1092

Options

  • The following versions are available:
  • –  F: round flanges, in-line delivery and suction ports, AISI 304
  • –  T: oval flanges, in-line delivery and suction ports, AISI 304
