A gear pump is mainly composed of gear, shaft, pump body, pump cover, bearing sets of spare parts. So these parts with what material? Introduce the gear oil pump commonly used material. Cast iron including grey iron and ductile iron. The gb code of the crucible for HT. My company has used the crucible HT200, HT150, HT250. General gear oil pump pump body, pump cover all use this kind of material of the crucible. Ball iron gb code for QT. Because of its mechanical properties close to steel, casting properties and processing properties and is better than just, so the material is a kind of comprehensive performance is good cast iron. Cast steel of gb code for ZG. The strength of material is higher. Can bear greater pressure, so the general bearing parts multi-purpose cast steel this material. The temperature requirements are quite widely, there is high temperature resistant effect. The price higher than the ordinary cast iron. Stainless steel is divided into austenitic stainless steel and martensitic stainless steel. Like cr18ni9 0, 1 cr18ni9ti is austenitic stainless steel, corrosion resistance effect is good. 3 cr13 is martensitic stainless steel. Usually the pump shaft and shaft sleeve material is chosen 3 cr13, because its mechanical performance better. The price higher than the ordinary cast iron. Carbon structural steel can be divided into ordinary carbon structural steel and high quality carbon structural steel. My company commonly used Q235 belong to ordinary carbon structural steel. Gear have stainless steel gear, used to transport the corrosion resistant materials and chemical raw materials, and the high quality carbon structural steel 45 steel has corrosion resistance effect, so much for pump pump shaft. The price higher than the ordinary cast iron
