SK Vacuum Pump Material

SK vacuum pump uses water as working fluid to extract vacuum, which provides help for many industries. In order to make the equipment use longer, besides correct operation method and usual maintenance, it can not be ignored in material selection. What material is it mainly made of?

1. Impeller stainless steel, over-current parts stainless steel and integral stainless steel.

2. Grey cast iron: Grey cast iron is the cast iron obtained by full graphitization in the first stage. All or most of the carbon exists in flake graphite, and the fracture surface is gray and dark. Usually used to make SK vacuum pump material.

3. Ductile iron: Ductile iron is spheroidal graphite obtained by spheroidizing and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than carbon steel. Its comprehensive performance is close to that of steel. It is precisely based on its excellent performance that SK vacuum pump can be cast.

It can be seen that the material used in SK vacuum pump is mainly stainless steel. This material can effectively reduce the rust of equipment, thus making the cleaning of equipment more simple and convenient, strengthening the hardness of equipment and reducing the damage to equipment.
