The new ILMVAC scroll pumps "Dry Run I and II" are intended
for use as dry-running vacuum generators in the laboratory and in industry.
The scroll pump can be operated either as a single pump or in pump
combinations. The ILMVAC DRY Run I and II have been conceived and developed as truly chemically resistant dry running pumps. The wetted parts receive as PTFE based proprietary treatment ensuring resistance to most corossive chemicals. However, chemical resistivity tolerance may vary according to the application. The pump has a gas ballast device which also ensures the pumping of vapours up to a defined maximum intake pressure. Should condensate form in the pump body, the unique vertical construction of the pump allows it to flow out of the pressure port easily.
The working pressure ranges from low to high vacuum. The dry running avoids pump oil particles from diffusing back into the suction port of the pump and on into the connected apparatus. The time consuming filling and draining of operating oil is also eliminated, which provides clean handling of the pump.
