We used advanced foundry technologies which contribute to the classic quality products. The mud pump equipment has two surfaces which can bear high strength to ensure high efficiency of the operation. We rigorously choose best quality steel in accordance with API, 7K and 8C to make sure it has a long service life. Those new technologies also help to provide smooth process surface and to make the welding seam smooth and even. Last but not the least, epoxy zinc-rich acrylic acid to paint was employed, so the machine is corrosion resistance.
