BOXER 503 ALU / Fuel transfer pump for industrial environments
DISCOVERCompany profile
The client operates in the liquid fuel storage and management sector. The Bertrange facility is a fuel depot dedicated to the storage of fuels, specifically petrol and diesel, in accordance with the strict regulatory and operational requirements applicable to this type of infrastructure. In such a sensitive storage environment, operations such as tank bottom draining, product recovery and controlled emptying require the use of an extremely robust fuel transfer pump that is easy to move and quick to connect to existing pipelines.

Application of the BOXER 503 ALU mobile fuel pump
The Boxer 503 ALU is used to transfer fuel from drain points located at the bottom of storage tanks. The main objective is to enable the controlled emptying and recovery of the product during normal operational, maintenance or depot management activities. Choosing this mobile fuel transfer system, equipped with double-diaphragm technology, is a particularly suitable solution:
- It allows fluids to be handled under varying operating conditions
- It does not require an electric motor fitted directly to the unit
- Installation on a trolley facilitates rapid movement between different points within the plant
- Quick-connect fittings allow rapid connection to the suction and discharge lines, reducing set-up times
To ensure maximum efficiency, the connecting pipework is kept to a minimum length, promoting stable operation, limiting pressure drops and facilitating priming during drainage operations.

Operating conditions of the mobile fuel transfer pump
Within the depot, the mobile fuel pump is used intermittently for draining, recovery and emptying operations. The Boxer 503 enables the movement of significant volumes of petrol and diesel in a short time, ensuring excellent flow continuity and extremely practical handling. Operational advantages include:
- No need for permanent installations
- Rapid and targeted operations in different areas of the plant
- A pneumatic supply that is easy to integrate into environments where a compressed air network is already in place
Safety note: In applications involving flammable fluids such as petrol and diesel, the configuration must be carefully assessed in light of the installation area, the environmental classification (ATEX) and the earthing and equipotential bonding procedures specified for the system.

Why choose a mobile fuel pump for a fuel depot
The customer required equipment that met very specific requirements. The Boxer 503 proved to be the ideal fuel transfer pump because:
- It is mobile and easy to transport
- It is robust and suited to the harsh industrial environments of fuel depots
- It ensures quick connections to existing lines, thanks to the quick-connect fittings supplied
- It is fully compatible for use with petrol and diesel
- It is suitable for draining tanks from the lowest point
- It reduces operating times during draining and maintenance
- It offers maximum flexibility, as it is not restricted to a single fixed location
The quick-connect couplings are a key feature of the design, as they speed up connection and disconnection operations, improving the ease of use of the entire system.
Results achieved with the fuel transfer pump at an ESSO depot
The adoption of the BOXER 503 ALU mobile fuel transfer pump, mounted on a stainless steel trolley, has provided the ESSO Oil Depot in Bertrange with practical and highly reliable equipment.
The ease with which the unit can be moved to different points within the depot and the reduction in connection times to the process lines have resulted in a significant increase in efficiency during draining operations. This solution has demonstrated how the integration of a robust pneumatic pump within a compact system can optimise o nd operational flexibility, providing excellent support for the complex day-to-day activities of a large fuel depot.
