Hydra-Cell High Advantages for Machine Tool Applications
Electrical Discharge Machining (EDM)
The injection of deionised (DI) water requires precise, consistent control down to very low flow rates at high pressures. DI water is corrosive, non-lubricating and can cause excessive maintenance with pumps with dynamic seals and packing.
Hydra-Cell’s seal-free, packing-free design, coupled with a constant accurate flow rate independent of discharge pressure, ensures a controllable dependable process.
Drilling
Consistent flow rate independent of discharge pressure ensures coolant is kept at the drill bit even in deep holes.
Grinding
During grinding wheel dressing fine sub 10 micron particles end up in the coolant. These are very difficult to filter but this is not problem for Hydra-Cell pumps with seal-less design.
Cleaning and degreasing
Hydra-Cell’s seal-less design, with many choices of materials of construction, enables many different chemical cleaning liquids to be used. Recycling the liquids and having suspended fine particles is not a problem for a Hydra-Cell pump.
High pressure capability ensures short cycle times and high productivity.
Deburring
Even at pressures at 350 bar, the Hydra-Cell seal-less design can handle the recycled deburring liquid without expensive seal flushing and regular maintenance.
Turning and Milling
No Problem Machining Cast Iron with Hydra-Cell
Machining cast iron generates a large amount of dust and fine powder, and when combined with machine tool coolant is difficult to filter out, creating issues for screw pumps.
It is the sub 20 microns particles which causes the damage to screw pumps! Hydra-Cell’s seal-less design can handle these solid loaded coolants reliably.
Long life and minimal maintenance costs
Any servicing is simple. With no dynamic seals wearing or tight internal tolerances to set or maintain, servicing can be carried out in any basic workshop. Depending on the duty, an annual oil change, and typically once every 2-3 years to replace a liquid end kit (only €300 to €700 depending on specification) is all that is required. A true “fit and forget” solution.
Energy efficient and reduced energy costs
Being a true positive displacement pump, the seal-less design of the Hydra-Cell pump eliminates internal flow losses giving overall efficiencies of 78% - 90% (pump-shaft to hydraulic power) resulting in significant energy savings; with no dynamic seals, this is consistent year after year.
