Top 12 Strainers

The same way we use sieves in our kitchens, several industrial applications require and depend on strainers. A strainer is used to separate large unwanted or foreign particles & components (which are usually solid) from fluids, gases, and sometimes even steam. Industrial strainers look very similar to a mesh screen made with wires, and the built-in micro-holes act as a barrier that filters out dirt. You will find a strainer installed in almost every pipeline system and flow equipment, be it in a commercial or residential setting.

Strainers Buying Guide

Besides filtering out undesired particles found in pipelines – an industrial strainer also does an excellent job at protecting the equipment and increasing their service life – especially the valves, pumps, regulators, control meter, steam trap, and other instruments. A strainer offers protection against conditions caused by high pressure & temperature, which is quite common with pipelines. Moreover, installing an industrial strainer can help avoid replacements and expensive repairs – particularly for automatic equipment as they are relatively high-maintenance. However, there are more factors a buyer must consider, and this buying guide is here to help.

The First Step – Figuring Out Which Strainer You Need

Before moving on to any other factor, one needs to determine which type of industrial strainer they need as there are many options. The most common variation is the suction strainer, widely used in pumps in combination with check valves to prevent dirt penetration. On the other hand, a swivel strainer simply works by being installed on the pump head to keep out debris. Similarly, the Y-shaped strainers offer more filter area and can be mounted vertically or horizontally, simplifying the piping system layout. So, buyers first need to figure out which type works best for them.

High-Quality Construction is a Must

After choosing a specific type of industrial strainer, buyers need to make sure it has a robust construction – which is a must since the primary purpose of a strainer is to protect flow equipment & system. When it comes to the material, there are many choices, including stainless steel, nylon, and plastics such as PVC. Although stainless steel is an excellent choice for the strainer’s filter screen (for high-precision straining), it isn’t so great for its exterior. It is better to go with strainers with a plastic outer body as it reduces the chances of corrosion and rust.

Make Sure to Take Proper Measurements

When it comes to industrial filters, correct sizing is highly essential and not just in terms of the diameter and height/length. You also need to consider the filter’s size as if it is too large; the unfiltered debris will move downstream and affect the equipment’s performance. Similarly, if the filtration size is too small, the pressure drop will increase – requiring more frequent cleaning. Therefore, buyers need to select an appropriate size based on their requirement for the best results.
