Open Pit Mining


A large open pit coal mine used to install dewatering pumps from European manufacturers and had issues with pumping water during heavy rain events and snow season when the water became mudy and loaded with solids. When the water became loaded with abrasive material a lot of problems started.

The problem

Water on site was changing all throughout the year from clear water to muddy, abrasive water causing the formerly installed pumps to fail.

The solution

Tsurumi GSZ and LH pumps were installed on pontoons to operate continously 24/7 throughout the year without failure. Extra motor power available on Tsurumi pumps proves very valuable in conditions like this, making the pumps handle contaminated liquids with ease. GSZ Tsurumi pumps remove mud around the big excavators to ensure a continous production of coal without interruptions of the process.

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.

In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
