i sent an email but got zero reply. how can i buy when you do not reply to inquiry. maybe i have to check other brands or suppliers with professional staffs.
hi, we have an similar principled pump but in our pump its not achieving deeper vacuum above -100 mmhg , i dismantled the pump to check carbon vanes & outer gaskets on both sides everything was fine but the pump was not able to suck in the oil from the sump, i checked for cloggings but nothing was there, if i pour oil directly into rotary chamber there's deep vacuum around -740 but only few seconds before the oil & air gets exhausted at high pressure into the sump but no suction of oil from sump happening again losing the seal at vanes & no vacuum, how to rectify this sir ? what am i missing?
