Water Pump Seals

NTB Hitech Ceramics manufactures over 150 different types of water pump seal faces for automobile, industrial, agricultural, and domestic water pumps. The pure aluminum oxide material offers excellent wear characteristics due to its hardness. The seal faces are designed to provide long lasting “ceramic/carbon” mating face with leak-proof contact between the rotating shaft and pump housing.

The extreme hardness, modules of elasticity and low thermal expansion of NTB Alumina ceramic ensures that they maintain their original dimensions under high load, high temperature conditions and aging. The excellent thermal stability guarantees precise fits over widely varying conditions of loading, speeds and vibrations. This makes NTB Alumina Seal faces a good choice in applications like mechanical seals for automotive, industrial, agricultural and domestic water pumps.

Chemical Pump Seals

NTB CERATUFF produces chemical seal faces which are the ideal choice for chemical pumps. The AL99.5 chemical seals are manufactured from submicron high purity alumina powder and are used for critical sealing applications in pump seals. The AL99.5 alumina provides resistance to most acids including hydrofluoric acid, solvents, salt solutions, molten salts, etc. It also provides good resistance to alkaline solutions in mild to medium concentrations.

These chemical seal faces give superior performance in corrosive fluids where all other materials fail because of the combined effect of corrosion, heat, pressure, and wear.
