Colleagues,<br>
<br>
We are in need of repairing/replacing our cleanroom process vacuum
pumps.<br>
Currently, we use a water sealed rotary vane system but it has been
suggested to convert to a oil sealed rotary screw style pump.<br>
We target an ultimate vacuum of 28mmHg and our volume requirements,
at point of use, are quite small (a couple spin chucks, end
effectors, etc.). Can anyone attest to having a rotary screw pump
installed for this purpose that has withstood the test of time? Any
issues with premature/frequent bearing failure or replacement?
Also, does changing from water sealed to oil sealed set off any red
flags? <br>
<br>
Thanks in advance,<br>
Bryant<br>
