PRESSURE DEVICES

At Grindaix we know the exact lubricoolant requirements of your machine tools.
Based on this knowledge, we are able to design the pressure supply technology

tion. Following a Coolant Audit® (see Services chapter), we select the pump that
is suitable for your applications and calculate the return on investment period.
In so doing, we take into account the applications in your central units as well
as the pressure boosting stations on individual machines or machine groups.
