Contvac vacuum equipment & systems
Girovac’s Contvac catalogue groups GVPDIF diffusion pumps and GVPDK two-stage rotary vane pumps. The two families perform different jobs: diffusion pumps form part of a high-vacuum installation, while rotary vane pumps can provide suitable backing or stand-alone pumping.
Build the complete high-vacuum arrangement
A diffusion pump needs the backing arrangement, operating fluid, cooling and installation controls specified for the selected model. The vacuum reached at the chamber also depends on pipework, gas load and cleanliness. Choose the high-vacuum pump and its supporting equipment together.
Select against the documented operating conditions
Compare connection sizes, pumping performance, electrical requirements and service access on the model pages. For a replacement, send the complete nameplate and existing installation details. Girovac will confirm the proposed equipment, configuration, condition and supporting documentation in the quotation.
