Internal Gear Pump R


The internal gear pump R is a positive displacement pump for liquids with a wide
range of viscosity, also with abrasive components like in cacao mass.

This internal gear pump in special executions from Sivag is very successfully used in the chocolate industry around the world. With our experience of more than 30 years, we have the best pump for your application no matter if you need to pump
cacao mass, chocolate or cacao butter.


  • Special executions for chocolate (0,5 - 20t/h)
  • Special execution for cacao mass (0,5t - 25t/h)
  • Special execution for cacao butter (0,5t - 25t/h)
  • Heating (jacket or cover)
  • Simple and robust design
  • Pumping in both directions
  • Inline version also available


We recommend for the cast iron for chocolate pumps. This ensures lowest cost and best performance. All pumps are also available in stainless.

Sensible parts for abrasion are delivered in highly abrasion resistant materials like hard metal to ensure a long life time
