SINCE 1997, HNA has been an integrated engineering & manufacturing specialist recognized worldwide for its unique World Leading HIGH PRESSURE Technology,  CERAMIC Technology, and HIGH PRESSURE FORGING, WORLD TOP CLASS HEAT TREATMENT & PRECISE MACHINING Technology, & high quaity products in the O&G industry, by designing and fabricating HNA Advanced High Pressure Ceramic Plungers for Triplex and Quintuplex plunger pumps, which are 100% interchangeable to most of the global famous brands: Halliburton, Weir SPM, Gardner Denver,Oilwell, FMC, OFM, Cooper OPI, SJ, Serva, JR, SANY & other major types of models, and customized design and production available.

HNA Advanced High Pressure Ceramic Plunger is significantly harder than metal plunger, and are tougher than any other ceramic liner available. The pure Zirconia ceramic used in these plungers are extremely resistant to abrasion,corrosion and heat and are currently the premium plungers offered today in its type. Due to the high hardness and low friction of the ceramic surface, they wear substantially less than other plunger types when the correct conditions are present, and greatly benefits the end users in reducing operation cost.
