In certain applications, tungsten carbide offers unique benefits in terms of mechanical properties, including fracture toughness, overall strength and elasticity.
Tungsten carbide substrate is often required on integrally geared, high-speed pumps using a clamped-in mating ring. When the mating ring is clamped between two metallic surfaces, tungsten carbide’s mechanical properties allow it to withstand the clamping. Because of its superior mechanical properties, tungsten carbide can also withstand high-speed centrifugal forces without outside diameter support.
Adding John Crane Diamond® to a Tungsten Carbide Substrate
There are many applications in which adding a seal face technology such as John Crane Diamond to a tungsten carbide substrate can improve mechanical seal performance. Common problems to look for are failure mechanisms such as heat checking, ID chipping, heavy wear and blistering. If evidence of one of these failure conditions is prevalent, adding John Crane Diamond seal face technology to the tungsten carbide substrate can help address these challenges.
Benefits of John Crane Diamond
Diamond is nature’s hardest known substance which leads to reduced face wear. Its low coefficient of friction results in less heat generation. The combination of these two characteristics provides additional protection to seal faces, helping overcome the common challenges mentioned above and extending the life of the mechanical seal.
In addition to increasing the mean time between repair (MTBR), adding John Crane Diamond material to a tungsten carbide substrate provides environmental benefits. With less heat generated, the need for cooling water and auxiliary cooling equipment is also reduced, resulting in lower energy consumption and reduced water usage. Compounding these benefits are the associated cost reductions in water consumption, wastewater processing and power usage.
PRODUCT AVAILABILITY:John Crane Diamond is available as an enhancement to many of their most widely used seal families, including: » T5600 Universal Cartridge Seal Family » T5800 Slurry Seal Family » 48VBF Boiler Feed water Seal » Other High-Performance Sealing Solutions
WHERE IT’S USED:Nearly every industry, including oil and gas, chemical, pharmaceutical, pulp and paper, water and wastewater, power generation and mining, can use John Crane Diamond to improve reliability and performance of mechanical seals, pumps and other components.

Want to extend the life of your pump? Tencarva offers various specialized coatings that can help prevent chemical and abrasive attacks on the metal of your equipment. We offer Belzona and Enecon as well as powder coating and enamels. If you are pumping aggressive chemicals or suspended solids in your fluids get familiar with these coatings to prevent unnecessary headaches from wear and corrosion.
The ZP3 from #AmpcoPumps is an excellent choice when pumping very high viscus liquids. Watch this video, demonstrating the manufacturing of soup cubes.
The raw material has a viscosity of more than 2 million mPas. It is very dry and needs a feeding screw to enter the rectangular pump inlet. The feeding conveyer overfeeds the pump with 120% to prevent air pockets. You also may see the very low pulsation with the Ampco ZP3 #circumferentialpistonpump. The ZP3 may handle up to 35 bar and is suitable for viscosities from 1 to 2 million mPas.
Other features are self-priming, suitable for metering applications, sensitive handling of liquids also with sensitive pieces, available in an aseptic version, #EHEDG certified and easy service.
The patented ZP3 Series positive displacement pump is the best choice for sanitary food and beverage processing because only the ZP3 is fully CIP-able without modification, while maintaining full efficiency. The ZP3 Series is EHEDG and 3A Certified. Manufactured and assembled in the U.S.A.
