Facts about Simplex Basket Strainers:

  • The simplex basket strainer is the most common basket strainer with one basket screen inside a strainer body.
  • Installed in a pipeline with uni-directional flow.
  • The Defender simplex basket strainer is used in a wide variety of applications, and the purpose is to filter out large debris from going futher up the system.
  • Protection of pumps is the main purpose but also for the avoidance of debris entering a system and causing blockages.
  • Sea strainers are the same as simplex basket strainers in that they filter raw water and large debris being sucked in by the marine water pump.

General information about Simplex Basket Strainers:

  • The basket strainer needs regular maintenance and should be emptied when flow is reducing. A differential pressure gauge will show a low pressure reading when the basket is full and needs cleaning out.  
  • A simplex basket strainer can only be installed on a pipeline system where a system shut down is permitted and possible to enable a simplex basket strainer to be cleaned out. A simplex basket strainer cannot be serviced whilst a pipeline system is in operation.
  • We supply high end basket strainer products, with 316 stainless steel strainer body designs for corrosion resistance, also Duplex 2205 stainless steel body designs.
  • 316 stainless steel body basket strainers are common with an internal basket manufactured from 316 stainless steel perforated sheet, to suit many mesh size requests.
  • The simplex basket strainer has less pressure loss than a Y strainer, less head loss than a Y strainer, a higher flow rate than a Y strainer, a larger volume and filtration area than a Y strainer, and is easier to clean than a Y strainer.
  • Different mesh sizes are available to suit each unique application and filtering requirement.

The purpose of Simplex Basket Strainers:

  • Simplex Basket Strainers are designed to suit most common pipe sizes, so that they can be installed in a pipeline, and filter the flow at the same flow rate of the pipe size.
  • To enable a high flow rate with a large filtration area is the main purpose of a simplex basket strainer.
  • Simplex Basket Strainers are manufactured from high quality materials so that they can filter the flow at the required pressure rating, and suitable to the media type.
  • Simplex Basket Strainers can be manufactured with different flange specifications so that they can be installed to mating pipe flanges.

Industrial applications for Simplex Basket Strainers:

  • Water systems
  • Oil systems
  • Mining process plants
  • Chemical process plants
  • Marine Industry

How to install a Simplex Basket Strainer:

  1. The simplex basket strainer is relatively easy to install in between two pipes with flanges on each end.
  2. The simplex basket strainer depending on its size and weight, may need lifting equipment to assist in lifting the basket strainer to the required position. The basket strainer flanges need to be lined up with the pipe end flanges.
  3. There should be a direction arrow on the basket strainer to inform the installer which way the flow direction is. The inlet side should have the internal basket opening, and the outlet side does not have any opening in the internal basket.
  4. Install the simplex basket strainer in the gap between the two flanged pipes, using nuts and bolts in the flange holes. 3mm thick gaskets between each flange connection will be required to seal the flange connections properly. Different gaskets will be required on high pressure and high temperature applications.
  5. If the flanges have 8 holes, then you will require 8 x nuts and bolts for each flange connection. 
  6. Install all nuts and bolts, and tighten in the required pattern.
  7. Before turning on the pipeline system, check that the internal strainer is clean and secure, and that the top lid and gasket is fully secured and tightened down for operation.
  8. Once the system has been operating for 30 minutes, check the nuts and bolts.

How to service a Simplex Basket Strainer:

  1. When the pressure reading on the simplex basket strainer is low, and flow is reduced, as if there is a blockage, it does mean that the internal basket filter has been filled by collecting all of the large debris that have not passed through the filter.
  2. To clean and service the strainer, the system will have to be switched off or shut down, so that the basket strainer lid can be loosened. It is impossible to service a simplex basket strainer with the system still running.
  3. Once the system has been switched off, servicing the basket strainer doesn't take long, only about 10 minutes.
  4. Undo the top bolts on the top lid of the strainer, this should not take long if the strainer has quick release T bolts.
  5. Remove the top lid and gasket, and place down on a work bench or something suitable to prevent damage.
  6. Pull out the internal filter basket screen
  7. Remove the drain plug, to drain out any contents, using a bucket or similar to collect the contents safely.
  8. Using a water hose or pressure washer, clean out the internals of the strainer.
  9. Empty the contents of the internal filter basket screen into a bin, and use a rag to clean any excess debris out.
  10. Use a water hose to clean out the internal basket screen if required.
  11. Place the internal filter basket screen back inside the basket strainer body, ensuring it is pointing in the correct way.
  12. Clean and inspect the gasket before placing on the top of the strainer. Replace the gasket if required.
  13. Clean and inspect the top lid before placing on top of the strainer and tighten the bolts.
  14. Fit the drain plug back in. Ensuring it is fully tightened.
  15. Finally ensure all bolts are fully tightened, so that the system can be turned back on.
