In the basement under the beam pumping engine is this air vessel on the pumping main. Reciprocating pumps need a 'shock absorber' to prevent the pressure of pumping from fracturing the pipes, especially unpleasant with a sewage pump. The air vessel has liquid at the bottom and compressed air at the top. The air is compressible and acts like a spring to store energy while the pump delivers and return it on the suction stroke, thus smoothing the flow in the pipes.
