Tough jobs, tough pumps

The Australian Mining Review - - COMPANIES GEARING UP -

AUSTRALIAN Pump In­dus­tries (Aussie Pumps) rein­tro­duced Tsu­rumi’s LH se­ries sub­mersibles to Aus­tralia’s min­ing in­dus­try six years ago.

The aim was to re­peat the great suc­cess achieved by the prod­uct in South Africa, the US and Canada.

Tsu­rumi’s LH se­ries rep­re­sents a breakthrough in de­sign and con­cept for mine de­wa­ter­ing pumps that face the harsh­est con­di­tions.

The sub­mersibles are cylin­dri­cal in shape; very dif­fer­ent to the con­ven­tional ‘broad belly’ de­sign.

The ob­vi­ous ad­van­tage for users is that Tsu­rumi pumps are equipped with high chrome iron im­pellers, de­signed for long last­ing ser­vice and per­for­mance.

The ranges starts with 100mm (4”) pumps all the way through to 8” pumps in a power ranged from 22kW through to 110 kW. The pumps will de­liver flows of up to 6500 litres per minute and heads as high as 150m.

They don’t break

Tsu­rumi’s whole pro­gram is based around ma­chines that are ca­pa­ble of pro­vid­ing con­tin­u­ous ser­vice with min­i­mal main­te­nance.

The unique, anti-wick­ing ca­ble en­try pre­vents wa­ter in­cur­sion due to cap­il­lary wick­ing. This means that even if the ca­ble is cut, dam­aged, or the end sub­merged the wa­ter that pen­e­trates the ca­ble can­not wick into the mo­tor.

The pump cham­ber has twin dual sil­i­con car­bide me­chan­i­cal seals. Th­ese seals are rated as 5 times higher cor­ro­sion and heat re­sis­tance than tung­sten car­bide. The unique de­sign in­cor­po­rates an oil cham­ber with an ‘oil lifter’ that en­sures com­plete lu­bri­ca­tion and cool­ing to all seal faces. Tsu­rumi LH se­ries: Mine Friendly The slim­line de­sign means the pump can be in­stalled in nar­row spa­ces.

It can even be used in bores and wells, sub­stan­tially re­duc­ing in­stal­la­tion costs. The flanged top dis­charge out­let en­sures the pump is bal­anced for lift­ing.

Tsu­rumi: The Min­ing So­lu­tion

Australian Pump’s co­op­er­a­tion with Tsu­rumi’s en­gi­neers has been re­warded with the fast-track­ing of pumps that par­tic­u­larly suit Aus­tralia’s min­ing mar­ket.

To­day, the ful­fil­ment of the pro­gram in­cludes 316 grade stain­less steel LH se­ries pumps from 22kW to 37kW and even as high as 110kW.

A com­pre­hen­sive free lit­er­a­ture pack is avail­able from Australian Pump In­dus­tries on (02) 8865 3500.
