Corrosive liquids on mining and construction sites are a fact of life. Pumps used for metalliferous mines are susceptible to breakdowns simply because the material of construction is not compatible with the required mid-range PH liquids. Tsurumi’s new 316 cast stainless steel high head pumps have been designed for such applications and challenges. Australian Pump Industries is working with Tsurumi to develop a range of big electro submersible pumps designed to deal with these issues.

The pumps are available in 316 stainless steel are now in a range of up to 110 kW with heads as high as 200m.

Called the Tsurumi LH series, the new pump claimed by API to change the way mines, quarries, industrial applications and even infrastructure projects think about moving inconvenient water fast.

Aussie Pumps’ Tsurumi Product Manager, Neil Bennett, said, “Tsurumi’s LH series will deliver flows of up to 6,500 lpm.

“They are loaded with features that Tsurumi has integrated as standard to maintain the highest levels of reliability.”

The big pumps, with their high flows and high head combination are designed in the unique ‘slimline’ that enables the pump to be used in bores and wells. For example, even the 110kW pump has a diameter of only 606mm.

Additionally, the pump incorporates a centred discharge flange that ensures the pump is ideally balanced for lifting in its installed position.

Discharge ports are up to 200mm (8”) and are flanged.

The pumps achieve their high performance by using two 316 stainless steel impellers. Pumps over 55kW are fitted with electro type leakage sensors and protection anodes where required.

Tsurumi’s anti-wicking cable entry prevents water getting into the motor if the power lead is damaged or the end submerged. Their unique double dual silicone carbide mechanical seal system is an added feature, and seals are incorporated in an oil chamber fitted with a patented ‘oil lifter’ that provides forced lubrication into the mechanical seals thus ensuring they always stay ‘wet’.

The extension of seal life and the anti-wicking cable entry point eliminates 90 per cent of the reasons of failure in submersible motors, dramatically extending the pump’s life and ultimately its reliability on-site.

“Tsurumi’s commitment to Australian Pump and the Australian market is tremendous,” Mr Bennett said.

“The establishment of the pump banks in Singapore and Japan mean fast delivery even if Australian Pump’s huge warehouse in Sydney doesn’t have product for immediate shipment.”
