PRECISION COOLANT SUPPLY SYSTEMS
The patented HELLMERICH rotary union – Europe patent 0319662
The HELLMERICH rotary union has been specifically developed for installation in confined and hard to access assembly areas while at the same time guaranteeing the greatest possible operational safety, as the central coolant supply of the working spindles of multi-spindle heads requires.
A dry run through the patented, non-contact sealing system is no problem at all. With the extremely reduced friction, only very low heating is achieved even at the highest speeds. Very easy to fit and pipe.
Product benefits:

• Smallest possible centre distances to neighbouring spindles
• Not sensitive to contamination of the coolant
• Not sensitive to radial forces
• High flow rate at high pressures with very small leaking rates
• Perfectly suitable for hidden installation on multi-spindle heads for revolver assembly or centre application (FMS)

Most requirements of the fields pneumatics, vacuum technology, or vacuum lifting technology can be fulfilled by products of our standard product range. However, there are occasionally special requirements which we gladly solve and manufacture corresponding special solutions for.
   
Examples for special solutions are: cylinder-valve combinations, printing machines paint supply systems, pneumatic control blocks, feedstuff distributing valves, special cylinders, special valves, large cylinders, coolant dosing system, 6/2 way valve, 3/2 start valve, silenced vacuum pump, double-stel cylinder, vacuum distributor, pneumatic timing, heavy duty vacuum cross beam.
