Due to a liquid flows ability to carry a very wide range of particles long distances strainer applications in liquids are many and various. From simple screens to complex self cleaning installations they vary in complexity and materials of construction dependent upon the service requirements of the application.
These units are employed widely and to meet a vast range of applications. They are various in nature and some of the typical forms are:
Flange, cone and disk are strainers that are placed directly into pipe work and are commonly used to ensure that commissioning contaminants do not migrate through systems.
Single strainers are pressure vessels that contain a mesh or perforated plate, normally in a basket form, these filters do not require the pipe to be broken to clean the baskets but process flow must cease.
Dual or Duplex Strainers are effectively two single strainers with an external or internal valve arrangement to allow flow to be directed through either or both baskets thus allowing cleaning while process flow continues or double flow for peak conditions.
Automatic or Self cleaning strainers vary in complexity from simple had operated units to fully automated systems. They typically employ either, scraper blades, low pressure backwash arms, vibration or clapping mechanisms or spring extension release systems.
Total Filtration can meet all of these requirements
