Overview

The Varisco V Series are a positive displacement internal rotary gear pump suitable for pumping viscous liquids without solids in suspension.  While solids cannot be handled by these pumps, they can cope with small abrasive particle.

Suitable for:

  • Chemicals: solvents, acids & alkalis, alcohols, pharmaceuticals, isocyanate, polyol, sodium silicate.
  • Petroleum Products: gasoline, diesel fuel, oils, additives
  • Soap & detergents
  • Adhesives: Glue, epoxy resins
  • Paint & ink: varnish, printing ink
  • High temperature: Bitumen, tar, asphalt, heat transfer liquids
  • Foodstuffs: molasses, chocolate, cocoa butter, glucose, vegetable oils, fat, animal feed.

Varisco V series gear pumps: Benefits

  • Constant capacity
  • Smooth flow, without pulsations or pressure peaks
  • Versatility. Simply by adjusting the axial position of the rotor, the same pump can handle water-thin liquids or high viscosity liquids
  • Reversibility. By inverting the direction of rotation the flow of liquid is reversed. Full performance is available in either direction of flow.
  • Rapid self priming
  • Simplicity. Only two moving parts: the rotor and idler gears, and only one shaft seal. 
  • Rugged, heavy duty construction. Low rotor speed.
  • Low rate of wear. 
  • Simple, minimal maintenance. Inspection without removing the pump, piping or drive.
  • Interchangeability. The modular design makes it possible to replace components with others in alternative materials or with different characteristics.
  • Variable port positions. The casing can be rotated on the bearing housing to take up different positions.
  • By-pass relief valve. This is mounted on the pump and can easily be adjusted. Double and heated versions are available on some models.
