Tsurumi LH4110-W dewatering pump

Tuesday, 22 July, 2014 | Supplied by: Australian Pump Industries Pty Ltd


Tsurumi has introduced a heavy-duty dewatering pump, 592 mm in diameter, which delivers heads of up to 200 m and a maximum flow of 1000 L/min. The LH4110-W pump is suitable for mining engineers and quarry and construction operators carrying out dewatering duties. The LH-W series is a superhigh-head version of the existing LH range.

The pump features two abrasion-resistant, high-chrome closed impellers and a centre-mounted discharge flange that ensures the pump is balanced for lifting. The range is available with discharge ports of between 50-100 mm and has a slimline design enabling the unit to be used in bores and wells. The pump is able to move water from substantial depths without needing to stage dewatering through ponds or tanks.

A fully lubricated dual silicon carbide mechanical seal, enclosed in an oil chamber, 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.

The anti-wicking cable block on the cable entry prevents water incursion due to capillary wicking should the power cable be damaged or the end submerged. This is claimed to eliminate around 40-50% of submersible pump failures. 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.
