Aussie Pumps begins 1000V mining pump field testing

Australian Pump Industries announces that Tsurumi’s 1000V submersible dewatering pumps will
soon begin trials at mine sites across Australia. Tsurumi’s Kyoto factory has
finished the design, prototyping, and laboratory testing for the pump model, which
is now ready for live mine environments.

distributor in Australia, Australian Pump Industries is working with key mine
operators on a program that will offer 11kW through to 110kW 1000V dewatering
pumps for field testing. Well known for their pumps’ advanced design and heavy
duty construction, Tsurumi has the capacity to build over 1.5 million pumps a

Australian Pump’s
John Kofron explains that the Tsurumi LH high head mining pumps offer real
advantages over the current models in terms of design and cost.

Tsurumi designed the
new 1000V series submersible pumps specifically to withstand the punishing
conditions found in harsh mining sites. The three phase pumps have flows of up
to 6,500 lpm and maximum head of up to 200 metres.

Already well
established in Australian mine and quarry applications, Tsurumi’s KTV and 3
phase LH series high head pumps have been selected by consultants and specified
by pump engineers in diverse projects including Gina Reinhardt’s Roy Hill mine.

According to Kofron,
these pumps have been built in line with Tsurumi’s no-compromise design philosophy
and are feature-packed to give mine operators the lowest possible total cost of

Key features of
Tsurumi’s 1000V pumps include inbuilt thermal protection in motors cutting power
on over current or extended dry run conditions; self-reset function allowing
the pump to automatically restart; anti-wicking cable entry preventing water from
entering the motor if the power lead is damaged or nicked; and double silicon
carbide seal provided as standard on all models with both seal surfaces
submerged in an oil chamber, away from the pumped liquid, ensuring lubrication
and protecting against ingress of foreign materials.

The mechanical seal
design features a patented Tsurumi oil lifter that increases seal longevity.
The lifter ensures both the upper and lower seals are lubricated and cooled,
even if the oil level in the chamber is low, or if the pump is operating out of

Kofron adds that Tsurumi’s pump features not
only eliminate the biggest failure points on any submersible pump but also
offer the assurance of a better product at lower cost, making the range perfect
for a mining industry application.
