Positive displacement internal gear pumps

They are used in industrial plants for pumping liquids of any viscosity without solids in suspension:

  • Chemicals products
  • Petroleum products
  • Soap and detergents
  • Adhesives
  • Paint and ink
  • High temperature liquids
  • Chocolate


Pumping of viscous liquids

Pumping of viscous liquids


V pumps are internal gear positive displacement rotary pumps. The flow is generated by two gears: the rotor and idler, one inside the other, separated by a crescent. As the gears rotate, liquid is drawn into the spaces created between the gears and the crescent. When the gears mesh, the liquid is forced out of the pump.


  • Constant capacity, directly proportional to the rotation speed and virtually independent of the pressure
  • Smooth flow, without pulses or pressure peaks which could cause vibrations in the pipework
  • Rugged, heavy duty construction. Low rotor peripheral speed. External pedestal bearing housing with oversize ball bearing to take axial and radial loads
  • Preheating. Heating chamber cast integral with the casing or mounted on the cover or gland.
  • By-pass relief valve. This is mounted on the pump and can easily be adjusted


  • Heavy duty casing in ductile iron, steel or stainless steel with flanged ports
  • Rotor and idler gears in ductile iron or stainless steel

Bushes in cast iron, bronze, graphite or carbon tungsten

SAXMAG magnetic drive

The magnetic coupling allows power to be transmitted without contact and with absolutely no leaks, thanks to the static seal.
Suitable for inflammable, explosives, polymerizing liquids
Compliance with ATEX standards
