Cummins CustomPaks equipped with Weir Multiflo high-capacity dewatering pumps

Twenty-two 1000 hp Cummins Inc. CustomPaks, built in Australia and equipped with Weir Multiflo high-capacity dewatering pumps, have been delivered to one of the world’s largest coal mining contractors for dewatering operations in Indonesia.

The mining contractor is one of Weir’s key customers for dewatering in the Asia Pacific region. Weir’s dewatering equipment is manufactured and assembled for global markets at its facility at Coolum on Queensland’s Sunshine Coast.

There’s no glory in mine dewatering, with bulletproof diesel workhorses and pumps required for relentless 24/7 operation in deep pits, lifting thousands of litres of water a minute to the surface. It’s a critical business.

Trusted workhorse
The CustomPaks are designed around Cummins’ QST30 engine, a 30-litre V12 continuous duty-rated at 1000 hp, a tried and trusted workhorse in dewatering with its combination of power density, flexible rpm range and proven robustness.



One of the 22 Cummins-powered dewatering pumps built for one of the world’s largest coal mining contractors.

While Cummins CustomPaks have earned a reputation for ruggedness, their ability to operate in intense heat is another feature. All CustomPak cooling systems provide for continuous operation in ambient temperatures of plus 50 deg. Celsius.

The CustomPaks for the Indonesian customer incorporate Weir’s Multiflo MF-420(EX) HV pump which is designed for high capacity, high head and heavy-duty mine dewatering due to its robust structure and materials of construction. The pump delivers a maximum flow rate of 340 litres/second or 1,200m3/h (at 200 metres head).
