The 12PSB-S is engineered to handle the rigorous demands of legacy automotive repair. As a robust multi cylinder diesel pump testing rig, it empowers technicians to accurately
measure oil supply capabilities across varying speed conditions, ensuring every cylinder operates in perfect harmony.
Versatility is at the core of this premium fuel injection pump tester. It features a highly stable variable frequency drive, allowing for seamless RPM transitions. Users can confidently
evaluate the performance of PE and VE pumps without the risk of power fluctuations under heavy loads.
Furthermore, the 12PSB-S excels as specialized mechanical engine governor adjustment equipment. By providing precise pressure readings and stroke counts, it allows workshops
to fine-tune traditional engine components, guaranteeing optimal fuel efficiency and restored power for older commercial vehicles.
