A German pump manufacturer building complete pumps for 'wet process' phosphoric acid production in South Africa specified Ferralium® 255 for the pump body castings, on the strength of its proven durability in identical duties worldwide.
This pump body casting in Ferralium® 255 is one of several supplied to a German pump manufacturer producing complete pumps for 'wet process' phosphoric acid production in South Africa.
The acid slurry handled contains 30% P2O5, 30% solids, plus H2SO4, HF and chlorides, so high corrosion and erosion resistance is essential for maximum operational life.
Ferralium® 255 (UNS S32550, Alloy 255, DIN 1.4507, ASTM F61) was specified for all wetted components because of its proven durability in identical applications worldwide.
