Oily sludge is a type of hazardous waste containing a variety of toxic substances. The selection of surfactant is particularly important in the treatment of oily sludge by surfactant washing (Zhao et al., 2005). The effect of rhamnolipids on oily sludge separation was investigated (Zhou et al., 2013). A maximum petroleum hydrocarbon removal .

Drilling fluids with complicated compositions are becoming more common as the oil and gas industry develops. The production of hazardous cuttings is increasing, which not only .
Centrifugal pump gland packing plays a crucial role in ensuring the efficient and reliable operation of centrifugal pumps. One of the key components of gland packing material is the graphite incorporated PTFE packing. This type of packing is designed to provide superior sealing performance and longevity in various industrial applications. In this article, we will explore the features, benefits, and applications of graphite incorporated PTFE packing in centrifugal pumps.
A safety margin of at least +50°C is assumed for centrifugal pumps operating without an additional gland cooling system. A good solution is the use of materials resistant to burn-out,
Graphite Incorporated PTFE Packing
Graphite incorporated PTFE packing is a type of packing material that is commonly used in centrifugal pumps for sealing purposes. It is made of traditional graphite incorporated PTFE yarn, which consists of double layers of graphite ePTFE. The yarn contains higher amounts of graphite, which enhances its lubricity and thermal conductivity, making it an ideal choice for high-temperature and high-pressure applications.
Features of Graphite Incorporated PTFE Packing
- High thermal conductivity: The presence of graphite in the PTFE yarn allows for efficient heat dissipation, preventing overheating of the packing material.
- Excellent chemical resistance: Graphite incorporated PTFE packing is resistant to a wide range of chemicals, making it suitable for use in various industrial environments.
- Low friction coefficient: The lubricity of graphite ePTFE reduces friction between the packing material and the pump shaft, resulting in smooth operation and extended service life.
- Superior sealing performance: The double layers of graphite ePTFE ensure a tight seal, preventing leakage and minimizing downtime.
Benefits of Graphite Incorporated PTFE Packing
- Extended service life: The durability and resilience of graphite incorporated PTFE packing contribute to longer intervals between maintenance and replacement.
- Reduced maintenance costs: The reliable sealing performance of the packing material reduces the need for frequent adjustments or replacements, saving time and resources.
- Enhanced pump efficiency: By minimizing leakage and friction, graphite incorporated PTFE packing helps improve the overall efficiency of centrifugal pumps.
- Versatile applications: Graphite incorporated PTFE packing can be used in a wide range of industries, including chemical processing, oil and gas, water treatment, and more.
Applications of Graphite Incorporated PTFE Packing
Graphite incorporated PTFE packing is suitable for various centrifugal pump applications, including:
- Water and wastewater treatment plants
- Petrochemical refineries
- Power generation facilities
- Food and beverage processing plants
- Pharmaceutical manufacturing
Types of Gland Packings
In addition to graphite incorporated PTFE packing, there are several other types of gland packings available for centrifugal pumps. Some of the most common types include:
In centrifugal pumps, gland packing is crucial. The maximum recommended linear velocity is about 15 m/s. When choosing packing, consider chemical resistance, shaft speed, …
An experimental study was carried out by Kinnarinen et al., (2015), aiming to compare the efficiencies of different dewatering and washing techniques for red mud filtration using a pilot-scale Outotec Larox® horizontal membrane filter press [30]. The effect of the washing ratio on the residual soda content of the filter cakes was studied .
