Dewatering Pumps

Weir Minerals has launched the latest edition in its range of Warman centrifugal pumps, the DWU dewatering pump, to the European market. The company says the pump is designed to deliver increased efficiency where water needs to be lifted over greater heights, a common requirement in both open and underground mines, and the unit delivers efficient operation at heads of up to 140m. Four different sizes are available, with outlet diameters of 75mm, 125mm, 150mm and 200mm and around 50% of the parts used in the

Getech is introducing its largest model of high performance centrifuge for sludge dewatering in the construction industry “We have built up extensive knowledge in the last 20 years of processing silts from aggregates, dewatering sludge from the construction of foundations, from quarries, from sand and gravel washing and also recovery of bentonite from weighted mud in vertical drilling applications,” says the company. “Nowadays we are able to offer solutions for individual applications using the very best te

Continuing its investment in the development of a range of super-silenced pumps, Sykes Pumps has launched its new MH150/100 Super Wispaset. Applications include pressure testing, batching plant washing, emergency or temporary fire mains and any situation where high vertical and/or long discharge runs are required. Employing a 129kW Iveco engine, the unit is capable of heads up to 105m, with a maximum flow rate of 320m³/hour and noise levels down to an average of 70dBA at 7m. The pump is set to run at 1,800r

A team of pumps from Tsurumi are working at one of Europe’s largest open air copper mines to keep it safe. Operated by Hellenic Copper Mines, the 4,000-year-old Skouriotissa copper mine in Cyprus is one of the oldest operational mines in the world. Integral to the day-to-day operation of the mine, the pumps remove groundwater, rainwater and highly acidic liquids (pH 2) unearthed by explosive excavation. The pumps have been working fault-free at the site for two years and counting. Pumping muddy water with l

In response to the mining and quarrying sectors’ concerns over pump and engine damage in situ, Pioneer Pump has devised a solution to protect its customers’ pump-sets. Based on Pioneer Pump’s original Rock & Rain protection, consisting of a painted carbon steel roof over both the engine and the pump, the new design aims to provide added protection to the sides of the pump-set, reducing repair costs and increasing equipment longevity.

Water removal in quarries is essential for good working, but much of the water is reusable within the site. Patrick Smith reports. Rubislaw Quarry in Aberdeen, Scotland, was opened in 1740, and during its 200-year lifespan an estimated six million tonnes of granite were excavated. The site, credited with giving Aberdeen its famous Granite City name (many buildings are constructed from the material), left one of the deepest man-made holes in Europe. When quarrying ceased, so too did daily pumping, and in the

Grindex has unveiled its upgraded drainage pump range and the company claims that the new design triples the durability of the units. The added service life comes from increased wear resistance in the impellor which has been achieved by preventing abrasive particles from reaching the vulnerable parts of the pump. The newly designed hydraulics section with its closed impeller dramatically reduces the performance drop caused by long-term wear, according to Grindex. Maintenance on the units has been improved w

Weir Minerals has launched a new website, DewateringExpertise.com, that uses interactive graphics to show which of its pumps are most appropriate for use in a wide range of mine and quarry applications. Covering underground and open-pit mining and quarrying as well as extraction of water from lakes, rivers, ponds and the sea for use in wet processes, the site makes it simple for operators to see quickly which of Weir’s wide range of pumps and other process equipment best fits their needs.
