Product DescriptionProduct DescriptionEMSCO FB1300/1600 Zirconia Ceramic LinerZirconia ceramic liners, primarily composed of yttria-stabilized zirconium dioxide (3Y-TZP as the most common grade), have emerged as a revolutionary alternative to traditional metal liners (such as high-chromium cast iron or stainless steel) in reciprocating pump systems, particularly in harsh industrial environments. Their rise to prominence stems from the unique synergy of mechanical, thermal, and chemical properties inherent to stabilized zirconia, which address long-standing pain points of metal counterparts—including rapid wear, corrosion-induced failure, and frequent maintenance downtime. Unlike brittle conventional ceramics (e.g., alumina or silicon carbide), 3Y-TZP zirconia exhibits exceptional toughness (≥ 10 MPa·m1/2) due to the "transformation toughening" mechanism: when the material is subjected to external stress, metastable tetragonal zirconia grains transform into monoclinic phase, accompanied by a 3-5% volume expansion. This expansion inhibits the propagation of microcracks, endowing the liner with both high hardness (exceeding 1250 HV, far harder than metal liners' 600-800 HV) and remarkable resistance to impact and fatigue—critical for withstanding the cyclic pressure fluctuations in reciprocating pumps, where the plunger repeatedly compresses and releases the fluid medium.In terms of operational performance, zirconia ceramic liners excel in two core aspects that directly impact industrial efficiency: wear resistance and corrosion resistance. Their ultra-high hardness minimizes abrasive wear caused by solid particles (e.g., sand, silt in oilfield drilling fluids or mineral slurries), extending the service life to 3-5 times that of metal liners. For instance, in oilfield water injection pumps, a metal liner typically needs replacement every 1000-2000 operating hours, while a zirconia ceramic liner can last 6000-10000 hours, significantly reducing maintenance costs and unplanned downtime. Chemically, zirconia is inert to most industrial fluids: it resists corrosion from strong acids (e.g., sulfuric acid, hydrochloric acid below 50% concentration), alkalis (e.g., sodium hydroxide solutions), and organic solvents (e.g., methanol, diesel), making it ideal for chemical processing,
