Gear pumps for viscous liquids

Victor gear pumps type R are used for liquids of any viscosity – including solvents, chocolate and bitumen. The liquid can be lubricating or non-lubricating and may contain abrasive particles such as color pigments.

  • Viscous liquids
  • Constant capacity
  • Constant non-pulsating flow
  • Self-priming
  • Longevity

R pumps are used in industries working in petrochemistry, paints and resin, soap and detergent, food and chocolate and paper. In short, all industries dealing with viscous liquids with high viscosity and therefore in need of stable gear pumps.


  • Self-priming
  • Capacity is directly proportional to the speed
  • Non-pulsating constant flow – therefore no vibration in fittings, valves or coupling
  • No foaming or churning of the liquid
  • Only one axle seal or with magnetic coupling
  • Moulded heat dissipation shaft into the house
  • Full performance in both directions
  • The chassis can be rotated and comes with 90° or 180° connection
  • Overpressure valve built into the pump
  • Heavy-duty construction - long service range
