Hayward Simplex Strainers

Basket strainers made of PVC, CPVC, GFPP, Platinum GFPP and Eastar (clear PVC)

 

Hayward polypropylene simplex strainerHaywards plastic simplex strainer is a thoughtful, user-friendly design available in PVC, CPVC and GFPP materials.  It's "rabbit ear" style chamber cover enables quick removal and access to the strainer basket without tools, which also reduces the potential for over tightening.  The bodies buttress style threads for the chamber cover provide a downwards oriented failure path, so in the event of over-pressurization the failure mode should be predictable and protect other system components from damage.  The chamber cover also has a conical shaped displacement geometry which serves two purposes, it reduces the volume of the chamber when accessing the basket and helps seal the strainer basket in-place via downwards pressure onto its handle.  The vent port is easily opened to bleed air from the system during filling and can be retrofitted with a valve if desired.

The strainer body has the same type of drain valve plug, which can also be upgraded to a drain kit with valve if desired.  The integrally molded base is flat with four slots to secure it to a mounting surface.  It has three true-union style ports (one inlet and two that can be used for outlets) because some applications require straight-through orientation where the inlet and outlet are 180° degrees apart and have the same centerline-to-grade dimension while others require the inlet and outlet located on the same side.  Thus the port that isn't used has a blank true-union cap and the other ports have either threaded, socket or flanged true-union connectors.

The true-union connection design simplifies installation as well as enabling strainer replacement without cutting and replacing piping; perhaps especially useful for socket glued piping connections.

The only elastomers used are captured o-rings for the chamber cover and true-union connections and o-rings for the vent/drain plugs.  The o-ring materials are either EPDM or FKM.

The strainer basket has an angled seating ring to match the angle within the strainer body, which helps prevent the strainer basket from rotating within the strainer when the flow is turbulent.  The strainer basket is made from the same material that the strainer body is made from with an option to upgrade to 316L SS.

One frequently asked question is: Are the strainers schedule 40 or 80?  The answer is "neither" because that terminology is used to describe the uniform wall thickness of piping and since these are molded products having varying wall thicknesses, they cannot have a specific "schedule" assigned to them.  What you need to refer to is the rated pressure by temperature chart to make sure that your application falls within the limits of the strainer material chosen.  Each of our simplex page has links to the catalog pages and the pressure/temperature charts.


Other significant aspects to consider include:

 

Plastic simplex strainers are used for liquids or environments that are aggressive to alloy strainers and are designed to be installed within non-alloy piping systems. If you intend to install a plastic strainer within an alloy piping system it is recommended that you install at least 10 pipe diameters of plastic piping upstream and downstream of the strainer to help account for differences in thermal expansion rates of metal and plastic, transmittal of pipe vibration and pipe loading forces.  Connecting plastic strainers directly with metal piping can potentially damage the strainer.
