Tsurumi Stainless Pump Solution

Model: SFQ Series 18th June 15

Australian construction sites and mines are often faced with the problem of moving contaminated water that is corrosive by nature. Cast iron submersible pumps are unable to cope with these conditions and often failure prematurely.

Tsurumi Pump have designed cast 316 stainless steel “SFQ” series pumps specifically for corrosive water applications including seawater, brine and even leachate in settling ponds.

“Contaminants can leach into collection ponds during construction when sub-layers are disturbed,” said Aussie Pumps’ Craig Bridgement. “Tsurumi Pump realised that cheaper grades of stainless steel don’t last under these corrosive applications. Their design uses a high grade of 316 cast stainless steel because of its ability to resist corrosion. This means the pumps require less maintenance” he said.

The SFQ range includes 2” and 3” three phase pumps with heads to 44 metres and flows to 2,000 lpm. They feature a high capacity semi open style impeller that will perform in even the toughest conditions.

The SFQ series of submersibles are unique in that even the stator housings are cast and machined 316 stainless steel. Casings, impellers and suction covers are also cast 316 stainless steel.

The grade of stainless steel used has a higher content of carbon for strength. It also has a high proportion of nickel and molybdenium for improved corrosion resistance. No welds are required which means no pitting and reduced oxidisation. This material is also capable of withstanding abrasive liquids.

“Our experience has been that Tsurumi pumps provide trouble-free reliable operation in corrosive applications around the world” said Bridgement.

Tsurumi incorporate a number of features that enhance the life expectancy of the pump and cut maintenance costs. These include a unique anti-wicking cable gland. Water is prevented from wicking down inside the cable. The motor is protected even if the cable is damaged or the end accidentally immersed.

All Tsurumi pumps have a double silicon carbide mechanical seal. Both seal surfaces are submerged in an oil chamber, well away from the pumped liquid. A patented oil lifter ensures the mechanical seal faces are always lubricated and cooled, even if the pump is installed horizontally.

Tsurumi Pump developed the product range in response to requirements in the Japanese market for super tough pumps for the chemical industry. Like all Tsurumi pumps, they are backed by a three year warranty against faulty material or workmanship.
