    API Mud Pump Bimetal  Liners:

    DL could supply four kinds of liners:

  1.Premium liners: DL premium liners combine the strength of a forged steel outer shell with the abrasion and corrosion reisistance of a high chromium iron inner sleeve. The liners feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minmum uniform bore hardness of HRC62. The inner surface of the liners with a mirror-like smooth finish and the inner holes’ dimension tolerance is strictly controlled to ensure a long using life of more than 800 hours. DL premium liners are made for superior performance under tough corrosive and abrasive conditions.

  2.Ceramic liners: DL ceramic liners combine the strength of a forged steel outer shell with the abrasion and corrosion reisistance of a ceramic inner sleeve. We supply Zirconia as well as Alumina sleeves, of which Zirconia performs better impact strength,higher hardness and be honed to finer surface finishes than Alumina.

   3.Chromium-plated liners: DL offers chrome-plated liners made from premium forged steel with the core plated by chrome. The Chromium-plated liners have hardening characteristics of 58 to 62 Rockwell C hardness.

  4.Hardened liners: DL hardned liners is normally used in mildly corrosive mud conditions. These liners are hardened and heat treated under strictly quality control,after which the hardness can reach more than 60HRC.
