Air Separator Float Device Pumping Unit Operation and Maintenance

Air Separator Float Device

On OIML Euro versions of the pumping unit, a float assembly is provided on the pumping unit

vent opening. This assembly is used to prevent liquid from escaping through the vent pipe. See

Figure 3-4.

Control Valve

The pumping unit uses a control valve that aids in the elimination of air by producing a back

pressure and is also used as a check valve for any fuel above it.

The control valve also contains a pressure relief valve. This valve relieves excess hose

pressure, which may result from the expansion of fuel in the hose during hot weather, to the air

eliminator chamber. This action prevents hoses from bursting and helps prevent pumping unit

leaks.
