Strainers Keep Things Running

Strainers are mechanical devices designed to filter out foreign particles from flowing water or other liquids and to prevent blockage and damage to liquid-cooled equipment, such as the cooling water intakes of marine engines as well as the pumps and compressors of industrial processes. As a strainer on a marine engine wears, it can be maintained using a groco strainer replacement part.

How Strainers Differ From Filters

The difference between strainers and filters are the size of the particles being removed: strainers are used when the particles to be removed are large enough to be visible; filters are used to remove particles that are too small to be seen with the naked eye.

Strainer Design and Use

According to projectmaterials.com, there are two basic types of strainers: Y strainers and basket strainers. There are also variations of each. Y strainers remove undesired solids from flowing liquids using a perforated or wire mesh straining element. They are used to protect regulators, steam traps, control valves, meters, and pumps. Y strainers can be installed vertically, if necessary.

Installed horizontally, basket strainers consist of a perforated or mesh lined basket. They are generally used in cases where a large amount of solid debris needs to be collected. Basket strainers can be installed in series when more effective filtering is required.

Duplex Strainers Prevent Shutdowns

A duplex strainer is a type of basket strainer used to prevent the flow of liquid from being stopped and consists of two separate basket housings and a valve. The valve is used to divert the flow of liquid to one of the strainers while the other is being cleaned. Self-cleaning duplex strainers are available.

Strainers are relatively simple tools that excel in preventing liquid-cooled equipment from getting clogged. Because of strainers, engines and industrial processes can operate without breaking down and without frequent interruption to clean out clogged equipment.
