Case study
Background
Operated by Hillgrove Resources the
Kanmantoo Copper Mine is located in
one of South Australia’s most under
explored regions, the Adelaide Hills.
The Kanmantoo processing plant was
commissioned in 2011 and was first
projected to operate with a throughput
of more than 2.4 Mt p/a, containing
20,000t of copper metal and associated
gold per annum. A mine extension
was approved in mid-2014 to further its
operating life to 2019.
The challenge
Kanmantoo’s two existing Warman®
AH®
12/10 pumps were each achieving a wear
life of only 300-800 operating hours.
They were using non-OEM wear parts
which required 10 pump rebuilds per
year.
A Weir Minerals’ engineer conducted
detailed analysis to demonstrate that
a Warman®
pump using genuine OEM
parts provides superior perfomance. In
addition, the analysis ensured that the
right pump was selected for the site’s
specific duties.
Hillgrove Resources saved up to AU$110,000
per annum in operating costs by installing
the Warman®
MCU®
250 pump at Kanmantoo
The solution
After evaluation of the duty conditions
and wear life of the Warman®
pumps
operating with the non-OEM wear parts,
Weir Minerals supplied Kanmantoo
mine with a 12 month trial of one
Warman®
MCU®
250 pump equipped
with OEM parts.The commitment
made to Kanmantoo was to reduce
their operational spend by AU$90,000
per annum.This was compared to the
existing installed pump operating with
non-OEM wear parts.
The Weir Minerals team provided
an innovative fixed cost supply plan
to demonstrate theTotal Ownership
Cost (TOC) savings to be achieved at
Kanmantoo by using the Warman®
MCU®
250 pump.The plan also included
a yearly cost comparison between the
existing incumbent parts and genuine
Warman®
pump parts.
Kanmantoo signed an agreement for a
monthly service structure under which
Weir Minerals serviced the Warman®
pump for the 12 month period.

Conclusion
Warman®
MCU®
250 pumps are designed for the most aggressive duties,
providing outstanding wear life and reliability. Ensuring availability of
spare parts and constant operational support through an experienced
team of qualified professionals, it was clear that the Warman®
MCU®
250
pump was the optimal pump choice for Kanmantoo mine.
The results
After a 12 month trial, the new Warman®
MCU®
250 pump achieved 2,500 operational
hours, more than 3 times than those of the existing Warman®
AH®
12/10 pump
working with non-OEM wear parts.
By reducing pump rebuilds from 10 times per year to only 3, the Kanmantoo
mine experienced an increase in labour availability due to the reduction in rebuilds
per annum.
The outstanding results of the Warman®
MCU®
250 pump with genuine Warman®
wear parts has assisted Kanmantoo Copper Mine to reduce downtime and increase
pump availability; and theTotal Ownership Cost (TOC) benefit for Hillgrove Resources
is a cost reduction of AU$110,000 per annum.
Hillgrove Resources has subsequently signed a second service proposal for another
12 months as a result of the high level of service, increased reliability of the pumping
equipment and lowerTOC.
