An underground roadheader in a copper mine in South Africa suddenly broke down while working in a tunnel 800 meters deep. At that time, the equipment was advancing the cutting head for operation, the pressure of the hydraulic system dropped sharply, the cutting head lost power, and the conveyor belt also stopped running. Maintenance personnel went down the well for inspection and found that the drive shaft of the original hydraulic pump was broken, the shell had cracks, and the oil leakage was serious. The original equipment manufacturer replied that it would take 12 weeks to customize the replacement pump, with a unit price of 15,000, which made John, the mine operation supervisor, very anxious - each day of shutdown of each tunnel would result in a loss of more than 80,000.

After John learned about KICAN from his peers, he immediately contacted the company's foreign trade specialist via WhatsApp. He sent the model parameters of the original pump, the working environment of the equipment and the fault video. Within an hour, KICAN's foreign trade specialist replied, saying that the technical team would handle it urgently.
Two days later, KICAN's technical proposal arrived in John's email: the customized KCP-320 hydraulic pump for him has a displacement of 320cc/rev, a rated pressure of 450bar, a peak pressure of 480bar, and a maximum speed of 3950rpm, which can perfectly match the hydraulic system of the roadheader. The quotation is only $9,200, and it is promised to be delivered by air within 12 days. The technical personnel of KICAN explained in the email: "We have an integrated production chain from raw material processing to finished product assembly, which can quickly complete customized production, and at the same time strictly control the quality to ensure product quality."
When the KICAN pump arrived at the mine, the maintenance team completed the replacement and installation in only 4 hours. When starting the roadheader, John was surprised to find that the equipment ran smoothly and the vibration was significantly reduced. After three weeks of high-intensity underground operation, the operator reported: "The cutting head is powerful in propulsion, the response speed is much faster than before, the pressure of the hydraulic system is stable, and the fuel consumption has also been reduced by about 10%."
John wrote in his thank-you email to KICAN: "Your products are not only price-friendly, but also of higher quality than expected, which has greatly reduced our downtime losses. We have recommended KICAN to other mines and look forward to more in-depth cooperation in the future."
