I have some questions here.
1. I need an ammonia pump (vertical can type) with specification : capacity 30 m3/h, total head 13.5 kg/cm2,
and NPSH A. = 0.4 m. Is it possible to get a pump  with dia. Of barrel < 700 mm and distance between
center line of suction nozzle and bottom of barrel < 1700 mm ?
2. Which material is the best for pump to handle Ammoniated phosacid, HA 28.5 : 654 SMO : HV 9
HA 28.5: 26-28 % Cr  : 5-7 % Ni  : 3-4 % Mo : 0.03-0.46  % C
654 SMO: 24 % Cr       :  22 % Ni  : 7.3 % Mo : 0.01 % C
HV 9   : 19-22 % Cr  : 24-26 % Ni  : >4 % Mo  : 0.04 % C


You'd be better off contating pump companies directly.  There 'might' be someone here who works for one AND who makes what you are looking for but IMO that's a long shot.
