Hydraulic pump - Wikipedia

When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed .

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 .

Contamination Control-Dehydrators

The resulting vacuum in the chamber has the effect of reducing the boiling point of the water in the fluid. This causes the liquid water to turn into a vapor and to be released from the oil. Any trapped gases are also released. The vacuum pump then removes the water and gas, and the oil .
