Triple Range Bottom Unloading Arm | Bottom Unloading Arm | Model 2454-BC

Triple Range Bottom Unloading Arm

The triple range bottom unloading arm (Model 2454-BC) is typically used for road and rail applications. This model is designed for unloading hydrocarbons products from a bottom connection point. This type of arm is mounted directly onto a riser post which is available on request. This is supplied with five swivel joints for vertical and horizontal positioning. The range and manoeuvrability means that it is easy to find and connect to the mating tanker connection.

Additionally, a compression spring balance cylinder is incorporated into this loading arm for ease of movement and a ball valve with a locking device for when it is in a closed position. The triple range bottom unloading arm can either be manufactured in a right or left hand configuration to suit your needs.

These are manufactured to ATEX / PED standards.
