Tsurumi Pump cast 316 stainless steel SFQ series pumps

Cast 316 stainless steel SFQ series pumps, supplied by Australian Pump Industries, are specifically designed for corrosive water applications. They are used around the world in industrial and even marine applications. Tsurumi Pump developed the product range in response to requirements in the Japanese market for super-tough pumps for the chemical industry.

The series is unusual 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 high 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. The material is also capable of withstanding abrasive liquids.

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

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. An oil lifter ensures the mechanical seal faces are always lubricated and cooled, even if the pump is installed horizontally.
