Voith Turbo product story

The EPAF variable-speed motor pump unit with the IPME internal gear pump was specially developed for the delivery of cooling lubricants.
Machine tools are becoming more and more powerful.
This also means that the requirements placed on the cooling lubricant circuits in the machines are also increasing.
Voith Turbo offers an innovative system for the delivery of cooling lubricants.
The EPAF variable-speed motor pump unit with the IPME internal gear pump was specially developed for the delivery of low-viscosity media.
Due to its renowned high efficiency, the IPME pump type is particularly suited as a delivery pump for the cooling lubricant circuit in machines with internally cooled tools.
A pressure-dependent drive speed control allows cooling lubricant to be delivered as and when it is required.
Pressures up to 100bar can be generated.
The EPAF system has a significantly higher efficiency than in conventional cooling lubricant feed systems with screw pumps.
One internal gear pump covers a considerably larger working range (pressure, delivery) and an accurate attainment of the most varied operation points of the tools (drill characteristic curve) is possible easily.
Reduced energy consumption, fewer components and automatic wear compensation are the main benefits of the EPAF system.
