Pumps used in alumina plants, please confirm

1: 150MP-34; Q = 220-280 m3/h; H = 34; operating temperature in alkaline environments: 100 degrees Celsius; Type 2 wear resistance. I’m asking experts to explain what kind of pump MP refers to here. Logically, MP should stand for magnetic pump, but magnetic pumps of the MP type all have low flow rates. What does Type 2 wear resistance mean? This pump is used in the Bayer process at alumina plants. II: C14AC51JMB; Q = 0.5–5 m3/h; H = 20–25 meters. This is used for screw pumps in dosing systems. What does C14AC51JMB mean? It’s the model number; I’ve been looking for it for a long time without success. I hope someone with expertise can help answer this question. .
First question: The 2 in question should refer to Class II and III materials, which are non-corrosion-resistant ductile iron or gray cast iron. The operating temperature of the pump is at room temperature, and the operating pressure should be below 2.4. Category II materials are carbon steel types that are not corrosion-resistant. The operating temperature of the pump is generally not higher than 250 degrees, and the operating pressure is not higher than 3–5 megapascals. Class III materials are stainless steels resistant to acidic corrosion. The operating temperature of the pump should not exceed 250 degrees, and the operating pressure should not exceed 5 MPa. Second question: The meaning of the screw pump model is unknown; one can only rely on the explanations provided by the supplier
This is an imported pump, right? Or it might be a pump made by a small manufacturer; I’ve never seen such a marking before. Take a photo of the nameplate and take a look. 1. Slurry pumps or desulfurization pumps used in alumina plants are more common with this kind of marking. 2. It’s a screw pump model, using a notation style similar to that of German brands. The codes refer to the pump’s specifications, material type, universal joint type, etc.; these are all internal codes, and one needs to consult the relevant manufacturer’s documentation to find out their meanings
