These new Oerlikon Leybold ScrollVac SC5D oil-free dry scroll pumps are a modern completely oil-free vacuum pump. They are inexpensive to operate and offer high performance in a compact design. They have a improved tip-seal material that requires less maintenance than competing foam backed tip-seals. These Oerlikon Leybold SC series dry scroll vacuum pumps are an excellent option to consider when upgrading from oil-sealed rotary vane vacuum pumps, as you avoid issues common with wet vacuum pumps, such as, routine oil changes, exhaust oil mist filters, backstreaming foreline traps, used waste oil disposal, and potential oil leaks. These Oerlikon Leybold SC5D dry scroll vacuum pumps can be set to operate on 1-phase 100-115 or 200-230 VAC at 50/60 Hz and have a pumping speed of 3.8 CFM.
The Oerlikon Leybold SCROLLVAC SC series dry scroll vacuum pumps are available in 4 sizes: SC-5D, SC-15D, SC-30D, and SC-60D. The Oerlikon Leybold ScrollVac SC series dry scroll pumps have a large pumping speed for their size which ranges from 3.8 to 42 CFM. We offer a wide selection of optional accessories including HEPA filter inlet traps, exhaust silencers, and maintenance rebuild kits.
Every Oerlikon Leybold ScrollVac dry scroll vacuum pump consists of two Archimedes spirals engaging each other with an offset of 180°. Thus, several crescent-shaped pockets of differing sizes are created. By means of an eccentric drive, a second spiral is made to orbit about a fixed spiral, thus reducing the volume of the pockets and compressing gases from the outside towards the inside thereby pumping the gases. Important to the quality of a scroll pump is that precise manufacturing tolerances are maintained and that suitable materials are selected. In order to maintain the performance of the pump, a standard maintenance is required after a certain number of operating hours. For this we are offering complete maintenance kits: small maintenance kit (Minor Kit) after 8,000 h or at latest after an operating time of 12 months and a large maintenance kit (Major Kit) after 16,000 hours or at latest after an operating time of 24 months of solid operation.
