Various features of the process require different delivery.
Pumps come in different sizes in terms of delivery and pressure.
In a given process the following pumps may be required:
- 300 litre/min at 10 bar
- 150 litre/min at 4 bar
- 50 litre/min at 1 bar
- 80 Litre /min at 70 bar
Often more than one machine may need to be connected to a system this may result in one system requiring 20 plus pumps due to the process.
This part of the process is all to often overlooked.
Water quality varies across the country so this should be taken into account. Hard water when mixed with a cutting fluid can make soap which will coat a filter and therefore impede the filtration process.
For water based coolant, 95% of the content is water so this has to be considered.
Due to evaporation a lower level of concentration maybe required along with de- mineralised water.
Pumping fluid can change the fluid character including adding air.
