Tsurumi SFQ stainless steel pumps

Tsurumi Pump SFQ series pumps are designed for use in corrosive applications including pumping fatty acids, citric acid, milk, brine and lactic acid.

The SFQ range includes 2″ and 3″ three-phase pumps with heads to 44 m and flows to 2000 Lpm, and a high-capacity semi-open style impeller.

The stator housings, casings, impellers and suction covers are all cast 316 stainless steel. The grade of stainless steel used has a higher content of carbon for strength and 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 anti-wicking cable gland prevents water from wicking down inside the cable, so the motor is protected even if the cable is damaged or the end accidentally immersed.

The 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 lubricated and cooled, even if the pump is installed horizontally.
