Daniel Okafor, Gulf Coast Refining, Port Arthur. We need a replacement transfer pump on the Unit 7 acid service. Spec is: - Media: 92% sulphuric acid - Operating temperature 150 C - Flow 60 m3/h - Wetted parts Hastelloy C-276, no exceptions — we've had 316 fail on this duty before - Area is ATEX Zone 0 Our maintenance system has AX-240 listed against this position. Please quote 2 units. This one is safety critical so I need it right rather than fast.

Hi Daniel,

Thanks for the enquiry. I've had this looked at against the duty you described, and I don't want to quote something that isn't right for it.

• Hazardous area rating: the duty needs ATEX Zone 0, and nothing in the range we can offer for this service goes beyond ATEX II 2G Zone 1 / None — general purpose / ATEX II 3G Zone 2.

Nothing in our standard catalogue covers this combination, so rather than offer a near-miss I'd like to put you in front of our application engineering team, who handle specials of this type. If you can send the full duty sheet — media, concentration, operating and design temperature, and the area classification for the installation — I'll get that moving.

Best regards,
Dana Whitfield
