High pressure cooling with Hydra-Cell
High pressure coolant delivery has many benefits in terms of metal cutting efficiency. It can offer dramatic reductions in cycle time of up to 70% while improving the quality of surface finish, extending the life of tooling and inserts and enhancing chip control. Many pump types offer the pressures and flows required for high pressure coolant delivery but one stands out in terms of reliability. Hydra-Cell®.
The problem lies in the fact that machining produces fines as well as chips; small particles of metal that are highly abrasive and, if not removed from the system by ultra-fine filtration will destroy any pump where bearings and seals are exposed to the pumped coolant.
Even the most efficient filtration system can fail; a bag filter can split or housekeeping may be inadequate as filters are changed allowing fines to pass through to the pump. Hydra-Cell pumps are designed to operate under such conditions and handle fines up to 500 microns in diameter removing the need for expensive fine filtration if not needed for surface finish requirements.
Should a filter become completely blocked, screw and gear pumps will tend to overheat as they need the pumped fluid for sealing and internal cooling whereas Hydra-Cell pumps will continue to operate without damage. Hydra-Cell pumps are also designed to run-dry indefinitely without damage.
