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.

Features and benefits

Horizontal swivel joints allow the arms to extend out to their full range and fold away into a small parking envelope.
Vertical swivel joints allow the arms to move up and down within a set range.
Spring balancing makes it easy to handle and maneuver by a single operator
Arms designed to suit specific liquids, with wetted materials including aluminium, carbon steel, stainless steel and PTFE lined versions. Ideal for LPG, Industrial Gases, and Pressurised Liquids.
Independent arms allow maximum flexibility for tanker connections.
Heated arms are available with thermal insulation and trace heating to maintain product at a constant temperature.

Case Study
The Duplex Bottom Loading Arm in action

We recently completed a project for a large-scale Chemical Manufacturer, helping streamline their loading operations. They were looking at ways to reduce manual handling on site, as well as reduce risks of leaks and spillages. See our solutions here.
