Varisco V Positive displacement internal gear pumps

Varisco V Positive displacement internal gear pumps

Positive displacement internal gear pumps for pumping liquids with any kind of viscosity, even with abrasive particles but, not containing solids. They are use in industrial plants.

  • Constant capacity, directly proportional to the rotational speed and virtually independent of pressure
  • Smooth flow, without pulsations or pressure peaks which could cause vibrations in the pipework
  • Rugged, heavy duty construction. Low rotor peripheral speed
  • Wide range of materials: ductile iron, WCB steel, AISI 316 stainless steel
  • Versions: ATEX and API 676
  • Viscosity: from 20 to 100,000 (mm²/s - cSt)
  • Temperature of the liquid: 200°C max (HT version: 300°C)
