One of very progressive thinking client had plans for larger mining activities on a long-term plan. Their aim is to deploy high performance pump set which can be used for years to come as they keep operating their coal mines at various depth and forward moving mines.
Their genuine demand was pumping system must be working non-stop, and asset usable for decades to come with least of maintenance.
DESIGN AND EXECUTION
Upon successful receipt of award entire team at RWTPL kicked into action and finalized various components of this unique pumping system as below.
- Heavy Duty High Head solid handling Mines dewatering pumping system with flow range of 4500 to 5000 GPM
- Vast head range of 95 to 200 meters head driven by custom 1140 HP motor
- Specially designed Solid handling mine dewatering NON SLAM Check Valve and Gate Valve.
- Customized modular Heavy Duty 1340 HP VV-VFD Drive system with climate control customized container, able to work in monsoon rain as well
- 400 meters of long coil PE pipeline with just two joints of high pressure operation and expecting decades of long life
- Custom steel rolled & fabricated, pressure, leak tested Pontoon able to handle dynamic loading up to 40 ton load
- Entire massive pumping system was dispatched within 3 months 10 days which any regular manufacturer may have taken at least 6 to 8m months considering magnitude of works involved
EXECUTION, COMMISSIONING WITH O&M BY RWTPL
RWTPL hand held client to assist in selection of client transformer & ACB
Completed full supervision of entire system erection and successfully commissioned entire pumping system.
Pump and pontoon was installed at deepest location in the mine sump strike length for effective dewatering without need for any shifting nor any regular manpower attendance
Pumps were delivering flow up to 1212 M3/hr at very Low 1230 rpm
Pumps can be operated all the way till 1800 rpm — Huge operational flexibility for client
Maintains volumetric efficiency close to 98% of its design rating, consumed just 323.44 to 370 KW/Hr
LONG COILED pipe having constant friction co-efficient factor impact in high energy savings
Pump was running 24×7 in the able hands of our O&M team
Conclusion:
The above system set an example of how a pontoon-mounted mines dewatering pumping system combined with flexible pump operational range along with CRUSH PROOF AND LEAK PROOF pipe can give greater benefits for client in dewatering and mines production.
