Re-plungering is a cost effective solution for the commercial marine industry. It is also an option when dealing with the challenges often experienced in the present environment of frequent fuel switching in SECA (SOx Emission Control Areas) and fuel quality issues due to the reduced lubricity of the ultra-low Sulphur fuels.

The team of Diesel Injection has been aware of this  for over 30 years. The experience gained in that time manifests itself in the quality of its service today and lead to investments in the latest state of the art of precision CNC and grinding machinery to manufacture there own wear parts with high quality certified steel. A large variety of new plungers are made this way and are kept in stock, which can be accurately built in during reconditioning.
