As the Strainers are so important integrant part of piping system and most commonly used in pressurized lines, of water, oil and gas networks, ZAFFERTEC S.L. has entered to sourcing of all kinds of Strainers with different applications.

You can make sure ZAFFERTEC S.L. Strainers are the best solution for the applications where small amounts of solid particulate are expected, and where clean-out will be infrequent. They can also be implemented in suction or vacuum conditions. 

We supply a complete range of Strainer types that are used in Oil, Gas, Petrochemical and Water treatment industries, such as: 

  • Tee type strainers
  • Y type strainers
  • Basket type strainers
  • Dual Basket type strainers
  • Conical type strainers
  • Temporary type strainers
  • Special items strainers
Strainer body is usually casting and Basket is stainless steel long life materials. Body castings and strainer screens are available in a variety of materials, perforations and mesh linings for virtually every application.
