It features Godwin's high-pressure oil bath me- chanical seal design, which enables dry running for prolonged periods while au- tomatically priming and repriming. The HL130M can handle solids up to 22 mm in diameter, making it an effective choice for both slurry and clean water applica- tions. It is offered with a choice of engine options and also is available in an elec- tric-powered confguration. The customer also asked Xylem Peru's Monitoring and Control Group to provide a solution for remotely controlling the new pumps. The Xylem team designed a system that could remotely start and stop the pumps, monitor capacity and fuel levels, and communicate operating parameters. To provide the customer with complete monitoring capabilities, the remote sys- tem was integrated with the mine's own SCADA system, with an HMI (human- machine interface) programmable dis- play on the pump control panel linked to the system, providing a full suite of parameters for equipment control and monitoring data. With the new system installed, personnel at the mine can control the pumps' fow and operation in seconds—compared to the original setup in which switching pumps required retrieving the power cable and disconnecting hoses, according to Coll. With the telemetry system designed by Xylem, the mine can quickly adjust the fow when heavy rain events occur. "The spotlight was on us because it was the frst time that this mining com- pany had employed a solution involv- ing end-suction, surface-mounted die- sel-driven pumps," said Coll. "There were a lot of expectations not only from the mine personnel but also mine upper man- agement. Other mining companies in the region were taking notice of the situation as well." According to Coll, the business rela- tionship between Xylem and the custom- er helped successfully implement the system. "We had a strong bond with the customer. Our technicians were there at the mine, working. We trained their em- ployees on the technology and provided the support for them," said Coll. The customer has been able to cut costs by eliminating the labor previously needed for manually controlling pumps or running electrical power down into the mine. It is now considering setting up similar pumping arrangements as it expands in Latin America, according to Xylem. The Godwin pumps are remotely controlled from this station, located away from the pit bottom and easy to reach when pumping adjustments are required due to weather or other factors.
