CNSME PUMP completes slurry pump retrofit at Chile mine

CNSME PUMP says it finished a major slurry pump retrofit at an Antofagasta, Chile mining site, cutting expected operating costs by about RMB 60,000 ($8,300) per pump each year. The project led to a new engineering assignment for a planned mine expansion and highlights demand for more efficient, longer-lasting pumping systems.

Why it matters: - The retrofit addressed a mining site with high throughput demands and chronic pump failures. - CNSME PUMP says the upgrade should lower annual operating costs by about RMB 60,000, or $8,300, per pump. - The project also led to a follow-on engineering order tied to a new mining expansion.

What happened: - Shijiazhuang Minerals Equipment Co., Ltd. (CNSME PUMP) completed a slurry pump retrofit at a large mining operation in Antofagasta, Chile. - The mine covers 492 hectares and includes 900,000 tons of titanium ore, 100 million tons of white silica sand and 4.6 million tons of yellow sand. - The site had been using locally produced pumps that did not meet the operation's production requirements. - The upgrade was finished in three months.

The details: - CNSME PUMP engineers conducted an on-site inspection before selecting AH Series Slurry Pumps. - The AH series is a heavy-duty horizontal centrifugal pump with a horizontal double-casing structure designed to simplify installation and maintenance. - The inner casing uses high-chromium alloy material and is meant to be replaced periodically as the main wet-end wear part. - The new pumps use a five-vane impeller and other wear-resistant wet-end parts to extend service life. - The shaft sealing system uses an expeller seal, removing the need for seal-flushing water. - The bearing assembly uses heavy-duty, grease-lubricated bearings and does not require an external oil station. - A belt-driven system was tailored to the site conditions and pump-motor setup. - After installation and commissioning, the pumps met the performance guarantees in the contract. - The retrofit reduced the original problems of low efficiency, rapid wear and high energy consumption.

Between the lines: - The project is a practical example of how mining operators are trying to cut energy use while improving equipment uptime. - The new order suggests the first retrofit gave the customer enough confidence to extend the relationship. - The lack of clean water and the harsh mining environment shaped the technical choices, which points to how site constraints can drive pump design.

What's next: - CNSME PUMP will develop a customized design solution for the new expansion project after receiving preliminary operating data from the customer. - The company plans to promote the Antofagasta project as a model for future energy-saving slurry pump retrofits. - CNSME PUMP says the project demonstrates how targeted pump upgrades can improve efficiency, reduce energy consumption and extend equipment life.

The bottom line: - CNSME PUMP turned a struggling mine pump setup into a lower-cost, more durable system — and won more business in the process.
