Internal gear pumps

Voith internal gear pumps are especially well-suited for any application in the low, medium, and high-pressure range, such as industrial manufacturing, Hydraulic Power Units and presses, plastics processing and wind energy.

Voith internal gear pumps feature very low pressure pulsation – typically up to 50% less than other comparable internal gear pumps. This considerably improves the controllability of the pump. It also reduces noise emissions by up to 6 dB(A).

Decades of design improvement have resulted in high volumetric efficiency. At rated speed, the volumetric efficiency of Voith pumps is often 5 to 10% better than other pumps on the market, improving your overall efficiency while reducing machine or system power consumption.

The internal gear pumps are available as:

  • single pumps
  • pump combinations (multi-flow pumps, multi-circuit pumps)
  • motor pump units
  • variable speed pumps
  • servo pumps
