Tsurumi stainless steel pump series

Tsurumi cast 316 stainless steel SFQ series pumps, supplied by Australian Pump Industries, are specifically designed for corrosive water applications. They are suitable for use in industrial and marine applications.

The SFQ series is claimed to be 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 molybdenum for improved corrosion resistance.

No welds are required, which means no pitting and reduced oxidisation. This material is also capable of withstanding abrasive liquids.

The range includes 2 and 3″ ports with heads to 44 m and flows to 2000 lpm. They feature a high-capacity, semi-open style impeller that will perform in tough conditions.

According to the company, inclusions such as an anti-wicking cable gland enhance the life expectancy of the pump and cut maintenance costs. The cable gland prevents water from wicking down inside the cable. The motor is protected even if the cable is damaged or the end accidentally immersed.

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.
