Fusion Bonded Epoxy Coated Cast Iron Basket Strainer Flanged to Table E with 304 Stainless Steel Mesh . All fixings and plugs are 304 Stainless Steel to resist corrosion. Allows a large flow rate with minimal pressure drop across the strainer. This basket strainer is great for waste water or other applications where straining needs to occur with as little as possible pressure drop. Much less than the equivalent size Y strainer. These Cast Iron Basket Strainers are tested in accordance with API 598.

  • What is a Flanged Cast Iron Basket Strainer?

    A Flanged Cast Iron Basket Strainer is a strainer that is made out of a fusion bonded epoxy coated Cast Iron Housing which contains a 304 Stainless Steel strainer element within it. The unit looks like a T shape with the entry and exit on the same plane and the strainer on the bottom of the T. The entry and exit are a Table E Flange and the strainer element can be accessed while the unit is inline by removing the bolts on the top of the unit. These Strainers are used inline to protect downstream equipment from suspended solids or debris of a size that the strainer element will catch.

  • How does a Flanged Cast Iron Basket Strainer work?

    The media enters the strainer and is then carried to the filter element inside the strainer. The exit is on the other side of the strainer element so it will flow through the strainer element while any particle will be caught in the strainer element as it cant fit through the holes. These are a very simple device as they have no moving parts and very valuable to all process lines as it offers a form of protection, quite often the first layer of defence. It is standard practice to use a strainer upstream in all process lines.

  • How do I maintain a Cast Iron Basket Strainer?

    Really the only maintenance that is required on a Basket Strainer is to clean the element. How regularly this occurs depends upon how dirty the media is. There are some indicators that the element needs to be clean usually by a bigger than normal drop of pressure or a decrease in velocity of the media downstream from the strainer. For maintenance the line must first be isolated and pressure removed from it. To clean the element the bolts on the top of the Strainer need to be removed. This will then allow the strainer element to be removed from the housing and cleaned. It can then be reinstalled and pressure returned to the line.

  • How do I install a Cast Iron Basket Strainer?

    There are really only two steps to follow to ensure a good installation of these flanged Y strainers. The first and most important is to ensure the direction of flow is followed. This is indicated by an arrow on the side of the housing. The next is to have the basket facing down (it will look like the T is on the bottom), a good way to tell this is to see the plug on the bottom of the unit is facing down. This is so any dirt or debris collected will sit at the bottom of the strainer element and will be very easy to remove when the bung is opened. It is best to install some sort of isolation valve before the strainer so the line can be isolated while maintenance occurs on the strainer. In this size a wafer or lugged butterfly valve are the most popular choices.

  • How long will my Flanged Cast Iron Basket Strainer Last?

    These will last for a very long time as they are made from Cast Iron and are very durable. The actual length of time will depend upon the media compatibility and how clean it is. Also the external environment will have some influence on the unit's lifetime.

  • What are typical uses of a Cast Iron Basket Strainer?

    These Cast Iron Basket Strainers are really used only on water and waste water. There are some other use cases but it is mainly water as the media.

  • How long will my product take to get to me? 

    This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.

  • What warranty do I get?

    All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all Strainers leave our warehouse tested and inspected so there are rarely any issues. Also once your Strainer is in and operating it will most likely continue to do so for a very long time barring any external factors and it is kept clean.
