PUMPS AND TURBOPUMPS FOR SPACE LAUNCHERS TEST BENCH
The facility was designed, executed and commissioned by COMOTI, for testing pumps and turbopumps under VEGA-E space launchers program. Successfully tested liquid oxygen turbopump (by similitude with GN2) and pump (electrical motor + gearbox - similitude with water) supplied by AVIO.
