  Features

The Eaton Model 570 Duplex Basket Strainer has been specifically designed to remove potential damage causing particles from large volumes of water and other process media (up to 30,000 gpm) efficiently and cost effectively. The strainer operates continuously and the pipeline flow never has to be shut down for strainer basket cleaning. Flow is switched from one basket chamber to the other by a sliding gate mechanism operated by hand wheels. The free floating valve disc mechanism moves easily and does not bind. The valve operating stem is fully enclosed, protecting it from the fluid flow.

Features/Benefits

  • Continuous flow — no shutdown for basket cleaning
  • Sliding gate design
  • Eight baskets per strainer (four per side)
  • Bolted cover
  • Compact
  • Threaded drain
  • Perforated or mesh stainless steel baskets standard
  • Synchronized drive for pressure equalization

The Model 570 is a multi-basket strainer, providing four baskets in each of the two straining chambers for a total of eight per duplex strainer. This makes the Model 570 a very compact unit for its size with a low profile, ideal for tight installations where space is a problem. Even if space is not a problem, why use a strainer that takes up more valuable floor space than is necessary?

The multi-basket design allows for smaller and lighter baskets than would be possible with a single basket. A single person can easily and quickly remove and clean the baskets without interrupting service. The baskets are designed with a unique, angled top to enable direct fluid entry which contributes to low pressure drop. Longer cycle times between cleanings are achieved by the large open area ratio of the baskets which have an incredibly high dirt holding capacity. This will save money in the areas of labor and downtime, over time.

Options

  • Bronze or stainless steel construction
  • Basket perforations from 1/32" to ½"
  • Basket mesh 20, 40 or 60
  • Monel® baskets
  • Vent valves
  • Drain valves
  • Cover lift davit
  • Pressure differential gauge and switch connections
  • Basket flange gaskets
  • Magnetic basket inserts
