  Features

Simplex pipeline strainers remove damage causing particulate matter from the process media, protecting system components such as flow meters, pumps, and spray nozzles. The particulate matter is captured in the strainer basket. The line is then temporarily shut down and the basket removed for cleaning or replacement.

The basic design is that of our popular time tested Model 72.The body and cover of the strainer are lined, not just coated, with Tefzel. This protects all wetted surfaces of the strainer making it impervious to attack by chemicals that can cause rapid deterioration of other types of plastics and all but the most costly metal alloys. The Tefzel fluoropolymer lining is inert to strong mineral acids, inorganic bases, halogens and metal salt solutions. Even carboxylic acids, anhydrides, aromatic and aliphatic hydrocarbons, alcohols, aldehydes, ketones, ethers, esters, chlorocarbons and classic polymer solvents have little effect on the Tefzel lining. Service temperatures can range up to 300F in many applications. The lining also displays excellent mechanical strength when handling abrasive slurries.

Features/Benefits

  • Excellent corrosion resistance
  • Abrasion resistant 1/8" Tefzel plastic lining
  • Service temperatures to 300F
  • Large capacity baskets
  • Flanged drain
  • Quick open cover
  • Low cost alternative to exotic alloy strainers
  • Standard perforated basket

A continuous lining of advanced fluoropolymer resin makes the Model 72L simplex strainer an excellent low cost alternative to exotic alloy strainers in a wide variety of corrosive or abrasive lined piping applications. These applications include waste water treatment, paper mills, hazardous materials, flue gas systems, ultra pure water handling, chemical and petrochemical processing.

Fitted with fluoropolymer coated baskets or mesh baskets made of Monel or Hastelloy C, these strainers can be used in almost any lined piping or similar corrosive/abrasive strainer application.

Options

  • Monel baskets
  • Hastelloy C baskets
  • Tefzel coated baskets

Applications

  • Wastewater
  • Spray Nozzle Systems
  • Heat Exchanger Protection
