Product Specifications
--Product Description
Slime pump is the core part in oilfiled drilling system with the mission of transiting mud to the downhole.
Ceramic pump liner is made by high-purity zirconia/alumina powde. We adopt advanced manufacturing process of cold pressing, high-temperature sintering, assembling and high-precision polishing to ensure its superior properties.
Specifications
The pump liner is characterized by following properties:
Excellent bending-resistance,
Excellent tensile strength,
Excellent fracture toughness,
Excellent corrosion resistance,
Excellent alkali resistance,
Excellent acid resistance.
High-purity: 95% zirconia or 99%, 99.7% alumina
