Interpretation of the model numbers on high-pressure centrifugal feed pumps for hydrogenation
Thread Content
What do the letters and numbers on the model label of the high-pressure feed pump in my factory, TDF70-120x9, mean? And a multi-stage pump means it has several impellers, right? Does that indicate the number of stages?
70-Flow rate, m3/h 120-Single-stage head, M 9-Number of stages
T: Double casing; D: Multi-stage; F: May be a special identifier for the company; 70: Design flow rate; 120: Head per stage; 9: Number of pump stages. The number of impellers corresponds to the number of stages in the pump.
I remember 70 should be the diameter of the inlet pipe, with everything else remaining the same. Please ask an expert to answer
T-----Cylinder band pump, double-shell design; D-----Multi-stage pump; F------Corrosion-resistant pump; TD-----Hydrogen feed pump; 70----Flow rate; 120--Head per stage; 9-----Number of stages
