No need for power supply, saving on the investment in large-scale power transformer construction. As the main and backup pumps, they can be installed in two or three sets, unaffected by power facility damage in case of fire, offering a higher safety factor. With the continuous improvement of diesel engine manufacturing technology, the starting performance of diesel engines is more reliable, comparable to electric fire pumps. The 6102Q, 6135 series, and 12V135 series diesel engines in the pump set configuration are all of excellent quality. Upon customer request, we can also provide high-end diesel engines from brands like "Cummins," "VOLVO," and "STEYR" from imported or joint-venture companies. Water pumps with anti-corrosion flow components such as mechanical seals, copper impellers, and stainless steel can be selected.
