I have a model ECVP425 vacuum pump from easy composites which has been running well for the past two years or so. When running the pump for more than 12hrs or so I generally feel the pump casing to make sure it's not getting too warm, and normally I can leave my hand on it as it only ever gets slightly warm. Yesterday however I noticed that it is getting *very* hot after just a few minutes running - I can not hold my hand on it for longer than 3-4 seconds before I risk burning myself!
My last infusion job (2' x 8') was problematic - the melamine covered chipboard work syrface I use became porous and started leaking air badly several hours into the infusion, so the pump had to work hard to maintain the vacuum while the resin cured. I had changed the oil in the pump only a short time before that but noticed yesterday when I drained the sump that it had become cloudy and emulsified with water (not sure where that came from - the chipboard perhaps?) I drained the oil and removed the bell housing covering the pump to check everything looked ok and to mop up any residual contaminated oil before refilling the pump with fresh oil... but it is still getting *very* hot very quickly. I don't want to damage the pump.
I don't want to disassemble the pump mechanism until I know what to look for, but such a job is well within my comfort zone.
Can you offer any suggestions?
Thanks,
Philip.
