Pump work principle is very complex, different pumps have different working principle,. To get a better sense of the pump, you'll need these mercury slides. Gear pump. Multistage centrifugal pump. Diaphragm pump. Diaphragm metering pump. High temperature separation type shielding pump. Basic separation type shielding pump. Rotz vacuum pump operating principle. Working principle of mixed flow pump.
The pumps in the DIP series are high-vacuum pumps -2 mbar. They are always operated in conjunction with forevacuum pumps. The DIP series pumps are water cooled and utilize the oil diffusion principle in their operation. They are employed in high-vacuum technology to evacuate vacuum chambers. They achieve their highest pumping speeds in pressure ranges from 10 -2 to 10 -7 mbar. The DIP pumps are fitted with a four-stage nozzle system made of light-alloy metal and with an internal heating system comprising heating cartridges and mounting wells to which heat diffusion fins are soldered. The mounting wells are made of stainless steel and are welded vacuum-tight in the pump body, in a horizontal position. The housing for the DIP pump is made of standard grade steel; the high-vacuum connection flange and the forevacuum connection are made of stainless steel alloy 1. The heat diffusion fins are made of copper and are only partially immersed in the pump fluid in the vaporization chamber. The section of the heat diffusion fins immersed in the pump fluid is dimensioned so that that intense but surge-free vaporization of the pump fluid is achieved.

Vane Pump Overview. While vane pumps can handle moderate viscosity liquids, they excel at handling low viscosity liquids such as LP gas propane , ammonia, solvents, alcohol, fuel oils, gasoline, and refrigerants. Vane pumps have no internal metal-to-metal contact and self-compensate for wear, enabling them to maintain peak performance on these non-lubricating liquids.
