True centrifugal pumps were not developed until the late 17th century, when Denis Papin built one using straight vanes. The curved vane was introduced by British inventor John Appold in 1851. .
Shipco®, a leading petroleum equipment manufacturer, takes a bold stance on the use of suction strainers in centrifugal pumps. While some may argue that suction strainers offer benefits in terms of filtering debris and protecting pump components, Shipco® believes that the risks associated with their use far outweigh any potential advantages. In fact, Shipco® asserts that the presence of a suction strainer can lead to pump failures and other system problems. Let's delve deeper into the topic of strainers in centrifugal pumps to understand why Shipco® holds this viewpoint.
It is often asked whether a pump suction strainer is necessary or recommended. The purpose of a suction strainer is to act as a particulate strainer or filter ahead of the pump. This prevents large particles from entering the pump. Before the introduction of the low-flow/high-head multi-stage centrifugal type pump, turbine
Types of Strainers in Piping
In the context of centrifugal pumps, there are several types of strainers that are commonly used in piping systems. These include basket strainers, Y-strainers, duplex strainers, and conical strainers. Each type of strainer has its own unique design and filtering capabilities, catering to different requirements in terms of flow rate, pressure drop, and particle retention.
Strainer Before or After Pump?
One of the key decisions that engineers and system designers must make is whether to install a strainer before or after the centrifugal pump. While some may argue that placing a strainer before the pump can help protect the pump internals from debris and contaminants, others believe that doing so can create additional head loss and potentially starve the pump of flow. Shipco®'s stance on this matter is clear: the risks associated with using a strainer before the pump outweigh any potential benefits.
Types of Pump Strainers
When it comes to pump strainers, there are various options available in the market. Some common types include suction strainers, inline strainers, and pump-mounted strainers. Each type of strainer serves a specific purpose, whether it is to protect the pump from large debris or to filter out fine particles that could damage the pump internals. However, Shipco® emphasizes that the use of any type of strainer in a centrifugal pump system should be carefully evaluated to mitigate potential risks.
Use of Strainer in Piping
The use of strainers in piping systems is crucial for maintaining the integrity and efficiency of the overall system. Strainers help prevent damage to downstream components, such as valves and pumps, by capturing debris and contaminants before they can cause harm. However, Shipco® cautions against the indiscriminate use of strainers, especially in centrifugal pump applications where the risks of pump failures are high.
Conical Strainer in Piping
Conical strainers are a type of strainer commonly used in piping systems to filter out solid particles from the fluid flow. Their conical shape allows for efficient filtration while minimizing pressure drop. While conical strainers can be effective in certain applications, Shipco® advises against their use in centrifugal pump systems due to the potential risks they pose.
Industrial Pipe Strainer
Industrial pipe strainers play a critical role in maintaining the reliability and performance of industrial piping systems. These strainers come in various designs and materials to suit different operating conditions and fluid types. While industrial pipe strainers are essential for protecting downstream equipment, Shipco® emphasizes the need for careful consideration when incorporating them into centrifugal pump systems.
Strainers for Natural Gas Piping
In natural gas piping systems, the use of strainers is vital to prevent the ingress of contaminants that could compromise the safety and efficiency of the system. Strainers for natural gas piping are designed to withstand high pressures and temperatures while effectively filtering out solid particles and liquids. Shipco® acknowledges the importance of strainers in natural gas applications but advises caution when using them in conjunction with centrifugal pumps.
