Duplex Bottom Loading Arm

The BLA-803 duplex or double bottom loading /unloading station reduces the risk of spills or accidents while loading and unloading bulk liquid road and rail tanks. These highly engineered arms are designed for applications where a liquid and vapour line are required for bottom loading or unloading operations.

These bottom loading arms are ideal for the loading of liquids that require very high or very low temperatures and can be used for cryogenic products as well as a range of hazardous and specialist liquids. The BLA-803 Loading Arm can be used to transfer all types of liquids including chemicals, solvents, acids, alcohols, sprits, highly flammable and highly corrosive liquids.
