A centrifugal pump is dead-headed when it is operated with no flow through it, for example, with a closed discharge valve or against a seated check valve. If the discharge valve is closed and there is no other flow path available to the pump, the impeller will churn the same volume of water as it rotates in the pump casing.

Energy is imparted to the fluid by a rotating impeller which increases the flow velocity and .
Packing for centrifugal pumps refers to the seals that are used to prevent leakage of fluid from the pump. It plays a crucial role in maintaining the efficiency and reliability of the pump system. Properly installed and maintained packing can help prevent leaks, reduce downtime, and extend the lifespan of the pump. In this article, we will discuss various aspects of centrifugal pump shaft packing, including types of packing, installation instructions, replacement procedures, and tips for adjusting the packing to minimize leakage.
Pump packing involves the use of soft, flexible materials—usually arranged in
Centrifugal Pump Packing Chart
Before selecting the appropriate packing for a centrifugal pump, it is essential to consider factors such as the type of fluid being pumped, the operating temperature and pressure, and the speed of the pump. Different types of packing materials are available, each with its own set of advantages and limitations. A centrifugal pump packing chart can help in determining the most suitable packing material based on these factors.
Centrifugal Pump Packing Instructions
Proper installation of packing is crucial for ensuring effective sealing and preventing leakage in centrifugal pumps. Centrifugal pump packing instructions typically include steps for preparing the pump shaft, cutting and sizing the packing material, and correctly packing the stuffing box. Following these instructions carefully can help optimize the performance of the pump and minimize the risk of leaks.
Centrifugal Pump Packing Installation
The installation process for centrifugal pump packing involves several key steps. First, the old packing material must be removed, and the stuffing box cleaned and inspected for any damage. Next, the new packing material is cut to the appropriate size and inserted into the stuffing box, ensuring that it is properly compressed and sealed. Finally, the gland follower is tightened to the recommended torque to secure the packing in place.
How to Replace Pump Packing
Over time, centrifugal pump packing may wear out or become damaged, necessitating replacement. When replacing pump packing, it is important to follow a systematic approach to ensure a proper seal. This includes removing the old packing, cleaning the stuffing box, selecting the appropriate replacement material, and correctly installing and adjusting the new packing.
Best Packing for PTFE Pumps
PTFE (Polytetrafluoroethylene) is a popular material for pump packing due to its chemical resistance and low friction properties. When selecting the best packing for PTFE pumps, it is important to choose a material that can withstand the specific operating conditions of the pump, such as temperature, pressure, and the type of fluid being pumped. PTFE packing is known for its durability and reliability in demanding applications.
How to Adjust Pump Packing
Proper adjustment of pump packing is essential for maintaining a tight seal and preventing leakage. Adjusting the packing involves tightening or loosening the gland follower to ensure the correct compression of the packing material around the pump shaft. Regular monitoring and adjustment of pump packing can help optimize the performance of the pump and extend its service life.

Every centrifugal pump has a BEP. At this point, the pump operates most cost-effectively in terms of maintenance and energy efficiency. As a result, the operating efficiency is highest, and the radial bearing loads are lowest. Factors that Deteriorate Pump Efficiency. Centrifugal pump efficiency boils down to three different efficiencies .
