A flush works by introducing clean process fluid or compatible liquid into the seal chamber. Its main purpose is to remove heat, flush away particles, and maintain a stable fluid film between the seal faces. The advantages of a flush include improved seal cooling, reduced wear, and prevention of dry running. Flush systems are most suitable for pumps handling clean or mildly contaminated fluids, high-temperature liquids, or applications with fluctuating operating conditions.
A quench functions by supplying an external liquid—often water or a compatible fluid—outside the seal faces, typically to dilute or cool any leakage from secondary seals. Its main advantages are protection against corrosive or high-temperature fluids and prevention of crystallization or hardening of residues around the seal. Quench arrangements are ideal for pumps handling hazardous, viscous, or crystallizing fluids where additional cooling and isolation are required to protect the seal and surrounding components.
Veekter’s engineers can recommend the proper flush or quench setup depending on your pump type, operating conditions, and fluid characteristics, ensuring optimal seal performance and extended service life.
The service life of an OEM mechanical seal typically ranges from 1 to 3 years under standard operating conditions. However, this lifespan can vary significantly based on several factors, including operating environment, fluid characteristics, seal design, and maintenance practices.
Factors Influencing Seal Life
Operating Conditions: Seals subjected to high temperatures, pressures, or speeds often experience reduced lifespans. For instance, pumps operating in cyclic conditions or with abrasive fluids may encounter premature wear.
Seal Design and Material: Seals made from high-quality materials like Silicon Carbide or Tungsten Carbide, and those designed to handle specific applications, tend to last longer.
Maintenance Practices: Regular maintenance, including proper installation, alignment, and monitoring, can significantly extend the life of mechanical seals.
Industry Standards and Expectations
According to the Fluid Sealing Association, operating a seal at its specified limits—such as pressure, speed, or temperature—can result in a minimum lifespan of 2 to 3 years, with some seal types, like those specified in Standard API 682, achieving this duration under steady-state conditions.
Mechanical seals and oil seals serve different purposes, so “better” depends on the application.
Mechanical Seal
Working Principle: Uses two flat, precision-machined faces (one stationary, one rotating) to prevent fluid leakage.
Advantages: Can handle high pressures, high speeds, and aggressive or hot fluids; provides a reliable, long-term sealing solution for pumps, mixers, and rotating equipment.
Best Application: Industrial pumps, marine pumps, chemical processing equipment, and applications requiring durability and minimal leakage.
Oil Seal
Working Principle: Uses an elastomer lip in contact with a shaft to prevent lubricant leakage and block external contaminants.
Advantages: Simple, low-cost, easy to install and replace; effective in retaining grease or oil in low-pressure environments.
Best Application: Gearboxes, automotive engines, axles, and rotating shafts where conditions are less demanding.
Conclusion:
If the system involves high pressure, high temperature, or corrosive fluids, a mechanical seal is the better choice.
If the application is low pressure, requires basic lubrication retention, and cost-effectiveness, an oil seal is more suitable.
