Industrial Packing for Demanding Applications

Industrial packing plays an important role in preventing and controlling leakage in industrial equipment. It is commonly used to seal pump shafts and valve stems, where operating conditions such as pressure, temperature, movement, and chemical compatibility can vary considerably.

Selecting the appropriate material can improve sealing performance and help reduce maintenance requirements.

The main options include:

  • Graphite Packing: Used in applications requiring thermal resistance and compatibility with certain industrial fluids.
  • PTFE Packing: Suitable for many applications where chemical resistance and low friction are important considerations.
  • Graphite-PTFE Packing: Combines properties of both materials for specific application requirements.
  • Carbon Fiber Packing: Used in services requiring particular mechanical properties and wear resistance.

The final selection should be based on actual operating conditions and the technical specifications of the individual product.

CPI Sealing Solutions for Pumps and Valves

Through its CPI Sealing division, CPI Prodysol offers products designed for a variety of industrial sealing applications. Its catalog includes graphite, PTFE, and other material-based solutions for specific sealing requirements.

For pumps, packing must be suitable for the shaft speed, operating pressure, temperature, and characteristics of the fluid being handled. For valves, selection should also take into account stem movement, operating cycles, and sealing requirements.

For this reason, selecting packing should involve more than considering dimensions or material alone. It is important to review the relevant technical specifications and confirm that the selected product is suitable for the intended operating conditions.

How to Select the Right Sealing Solution

Before specifying packing for a pump or valve, it is advisable to evaluate the following parameters:

  • Fluid type and chemical compatibility: Confirm that the selected material is suitable for the fluid being handled.
  • Operating temperature: Consider the minimum, normal, and maximum temperatures.
  • Operating pressure: Check the pressure conditions under which the equipment will operate.
  • Equipment speed and movement: Evaluate shaft speed, stem movement, and the type of operation.
  • Equipment dimensions: Verify the dimensions of the shaft, valve stem, and packing chamber.
  • Maintenance requirements: Consider the maintenance schedule and any application-specific operating conditions.

Having this information available helps identify a compatible sealing solution and can reduce problems associated with incorrect product selection.
