Basket strainer

A basket strainer is a type of strainer that utilizes a filter basket. Basket strainers are designed to be placed directly between pipelines to capture solid particles. A basket strainer consists of a filter housing with connections that correspond to the piping, containing a filter basket made from a perforated plate. The openings in this perforated plate are a few millimeters in size, but can be coated with a filter mesh to reduce the pore size/micron rating down to as low as 5 microns. Basket strainers are available in various materials, pressure classes, and connections for both inlet and outlet. A common application is the protection of pumps and other equipment; however, basket strainers are also designed to function as surface filters in various industries and processes, making them a versatile type of filter.

Usage of the Basket Strainer

Basket strainers are one of the types of filter strainers offered by Van Borselen, alongside temporary strainers, Y strainers, duplex strainers, T strainers, and simplex strainers. While temporary strainers are primarily intended for short-term use, such as during startup phases of production, basket strainers are intended for permanent filtration. As mentioned, these filters are placed directly within the piping to capture solid particles. A basket strainer can remove particles from liquids as well as gas streams. Furthermore, basket strainers are employed across various industries, including the food and beverage industry, to protect pumps and other equipment, as well as in the chemical and water industries. Thanks to the wide range of materials, connections, and capacities available, there is a suitable type of basket strainer for every process. However, a basket strainer contains only one filter element. If it is necessary to switch between two separate strainers, a duplex strainer is required.

Different Connections

Basket strainers can be designed with flanges featuring ANSI or DIN connections. The design can thus be customized to meet the specific requirements of your process.

Difference Between Basket Strainers and Simplex Strainers

Basket strainers and simplex strainers appear similar but have different characteristics. A basket strainer uses a larger basket-shaped filter element, whereas simplex strainers have a smaller cylindrical filter. Due to this design difference, a basket strainer offers several advantages over a simplex strainer. The basket strainer is used in productions and applications that require higher flow rates and greater debris capture capacity. Cleaning and maintaining the basket strainer is generally less frequent due to the larger capacity of the filter basket compared to a simplex strainer. This reduces operational costs in your production or application, thus improving efficiency in your process.
