Performance characteristics

Note: The performance characteristics described below are for use with hydrocarbon oil.
The positions of the mode selector and the gas-ballast control define the performance characteristics of the pump.
These performance characteristics are listed fully in Table 3 and Table 4.
Table 5 gives the ultimate vacuum and maximum water vapour inlet pressure for each of the six possible
combinations of control positions. The curves 0, I, and II in Figure 2 show the relationship between inlet pressure and
pumping speed for High Vacuum mode 
