A new Tsurumi heavy duty dewatering pump that delivers heads of up to 200m will change the way mining engineers, quarry and construction operators carry out dewatering duties.

The new LH4110-W was introduced by Australian Pump Industries (Aussie Pumps), the sole Australian distributor for Tsurumi.

Aussie Pumps product manager Craig Bridgement said the ability to use one pump to get up to a 200m total head was a huge breakthrough.
“To think that Tsurumi have been able to achieve this with a pump that provides a 1000 litre per minute maximum flow, but is only 23 inches (592mm) in diameter, is a revolution,” he said.

The Tsurumi LH-W series is a super high-head version of the existing LH range. The models feature two abrasion resistant, high chrome closed impellers and a centre mounted discharge flange to ensure the pump is balanced for lifting.

The range is available with discharge ports of between 50mm and 100mm (2 to 4 inches) and the slim line design enables the pump to be used in bores and wells.

The big benefit for operators is the pump’s ability to move water from substantial depths without needing to stage dewatering through ponds or tanks. This creates huge cost reduction opportunities for contractors.

The LH4110-W incorporates all of Tsurumi’s standard features that combine to build one of the most reliable pumps on the market.

Tsurumi is also working on a 316 stainless steel version of the big LH-W high end pump for the mines where there are specific corrosive liquid issues. A 1000 volt version may also be available in coming months.
