Tsurumi LH4110-W submersible dewatering pumps

Friday, 15 August, 2014 | Supplied by: Australian Pump Industries Pty Ltd

The Tsurumi LH4110-W is designed to improve the way mining engineers, quarry and construction operators carry out dewatering duties. The LH4110-W can achieve up to a 200 m total head while providing a 1000 L/min maximum flow, but is only 592 mm in diameter.

Tsurumi’s LH-W series feature two abrasion-resistant, high chrome closed impellers and a centre-mounted discharge flange that ensures the pump is balanced for lifting. The LH-W range is available with discharge ports of between 50 and 100 mm, and has a slimline design, enabling the pump to be used in bores and wells, with major cost reductions for users.

The LH4110-W is a fully lubricated dual silicon carbide mechanical seal enclosed in an oil chamber. This eliminates spring failure caused by corrosion or abrasion and keeps both surfaces of the mechanical seal lubricated and cool.

An oil lifter guide vane inside the oil chamber ensures the mechanical seal is lubricated even if the oil level falls. This increases the time between routine pump maintenance and extends operating life.

An anti-wicking cable block on the cable entry also prevents water incursion due to capillary wicking should the power cable be damaged or the end submerged. Tsurumi claims this eliminates around 40-50% of submersible pump failures, again delivering lower operating costs and significantly improving reliability.

The pump comes with a 2-pole, 415 V motor, driving the impeller through a high-tensile, stainless steel shaft supported by deep groove ball bearings.
