  • Pump body, motor casing, handle, suction grille in AISI 304 stainless steel;
  • Stamped brass supports;
  • Impellers, diffusers and separators in glass-filled PPOm, each stage is complete with a stainless steel wear ring;
  • Crankshaft in AISI 430 stainless steel;
  • Mechanical seal in alumina graphite lubricated with oil;
  • On request in SILICON CARBIDE;
  • Special lip seal for sand protection.


MOTOR :


  • Asynchronous single-phase V.230 50HZ or three-phase V.400 50HZ;
  • Other voltages and frequencies on request;
  • Insulation class F;
  • Internal cooling in a bath of non-polluting food-grade mineral oil;
  • External cooling by pumped liquid;
  • Built-in thermal protection.
  • In the single-phase version, the capacitor can be inserted inside the pump or supplied together with the external control panel.
