Vacuum pump - Wikipedia

History Early pumps. The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire. The suction pump later appeared in medieval Europe from .

Wet Vacuum Pump - Piper Flyer Association

New to the forum but found nothing in the search function, so here goes. I have an Apache/Geronimo with 2 wet vac pumps. The left side stays relatively dry but the right flap gets dripping wet after 10 or so hours. I did a run this morning (3-5 minutes) with a rag covering the vacuum pump output hose in lieu of it going into the (tiny) separator.
