Introduction
A dead-head is caused when a centrifugal pump operates with no flow through the pump due to a closed discharge valve or blockage in the line. The pump is forced to circulate the pumped medium, causing the temperature to
Aug 23, 2021 - A deadhead is when a centrifugal pump continues operating without any fluid flowing through the pump. Deadheading results primarily due to a closed discharge. In this article, we will explore the implications of deadheading a centrifugal pump, the problems it may cause, the pressures involved, how to prevent deadheading, and the causes of deadheading.
Deadheading of Centrifugal Pump
Deadheading a centrifugal pump occurs when the pump operates with no fluid flow, leading to a buildup of pressure within the pump system. This situation can have detrimental effects on the pump and its components if not addressed promptly.
Dead Head Pump Problems
When a centrifugal pump is deadheaded, several problems can arise. The most common issue is the buildup of excessive pressure within the pump, which can lead to mechanical damage, overheating, and potential failure of the pump. Additionally, deadheading can cause cavitation, vibration, and increased energy consumption.
Dead Head Pump Pressure
The pressure within a deadheaded centrifugal pump can increase significantly, depending on the pump's design and operating conditions. This high pressure can cause stress on the pump components, leading to premature wear and potential failure.
How to Dead Head a Pump
Deadheading a centrifugal pump is not recommended as it can cause severe damage to the pump and its components. To prevent deadheading, it is essential to ensure that the pump always has a proper flow of fluid through it. Monitoring the pump's operating conditions and addressing any issues promptly can help prevent deadheading.
How to Prevent Deadheaded Pump
To prevent a centrifugal pump from deadheading, several measures can be taken. These include installing pressure relief valves, flow control devices, and monitoring systems to ensure that the pump always has a sufficient flow of fluid. Regular maintenance and inspection of the pump can also help prevent deadheading.
Deadhead Pump Causes
Deadheading of a centrifugal pump can be caused by various factors, including closed discharge valves, blockages in the piping system, incorrect pump sizing, and improper pump operation. Identifying and addressing these causes can help prevent deadheading and ensure the efficient operation of the pump.

Three screw pumps Three screw pumps are produced in two basically different designs, single ended and double ended. The double end (double suction) design, Figure 4, is balanced in the .Single screw pumps also have the following disadvantages 1) The efficiency is low, about 30%~40%. 2) Due to the sliding friction between the sleeve and the screw, the wear is fast, and the seal needs to be replaced .
