While the facility started out with pumps from different manufacturers, over the last 10 years it has turned entirely to Tsurumi pumps to establish a reliable and cost-effective dewatering system.

Six of the newest additions to the system, which must move large amounts of mud, slurry and gravel continuously, 24 hours a day, are high-volume, three-phase dewatering GSZ-150-4 pumps.

"Crucial to the mine's choice of the GSZ pumps was their flow capacity, which is powerful enough for the requirements of its operations," said Larry De la Torre, president of Clowe & Cowan, a Tsurumi distributor in El Paso, Texas.

"Representatives from the mine told us they needed pumps to draw a lot of water quickly, that's why we recommended such powerful pumps. There are similar pumps from other brands out there, but only Tsurumi combines quality, reliability and reasonable prices, they said."

The GSZ series is one of the most formidable high-volume submersible pumps available, with capabilities to pump up to 5,000gpm. With impeller materials of high chrome and stainless steel, the GSZ series tackles the most aggressive dewatering applications.

"Tsurumi's products are known for their strength and quality, and that's exactly what the managers of the Chihuahua mine were looking for," said Vicente Marín, sales manager at Representaciones Industriales Marin (RIMA), a Tsurumi distributor in Mexico. "With a reputation for great durability, some of its pumps can even be found working today after more than 25 years active service."

Today the Chihuahua plant has about 80 Tsurumi pumps in operation. In addition to the six GSZ-150-4 models, the facility employs dozens of pumps from the LH (medium to high flows at high head) and LHW Series (extremely high head capabilities), including the LH411, LH422, LH6110, LH645, LH25.5W and LH430W.
