Simplex vs. Duplex Strainers For Industrial Liquid Processing

Many industrial and commercial liquid systems have mechanical components that cannot tolerate particulate matter in the liquid. Pumps, valves, sensors, and other specialties can experience accelerated wear and tear due to certain types and sizes of particulate matter.

Good practice dictates that the tolerance of the system for particulate matter should be determined and a properly sized and configured device be put in place to remove particulates larger than greatest allowable size. Considerations for connection size and type, construction material suitability for the process media, flow rate, pressure drop, and filter holding capacity should all be a part of the product selection criteria.

One key element of the selection criteria is whether the system can be temporarily shut down for replacement or cleaning of the filtration element. A basket strainer, one of several types of liquid filtration devices, is available in both simplex and duplex variants. A simplex basket strainer functions as a single unit, requiring flow stoppage when the basket becomes clogged with debris. The changeover time may not be long, but some processes cannot tolerate any downtime. A duplex strainer is comprised of two simplex strainers, incorporated into a common housing, with an inlet chamber and diverting valve that selects which strainer basket will process the liquid flow. Changes in pressure drop through the device can be used to signal when it is time to switch operation between the strainer baskets.

Fluid filtration can be an important part of keeping a process in operation, reducing wear and tear on piping system components and equipment. Share your process fluid filtration challenges and requirements with application specialists, combining your process knowledge and experience with their product application expertise to produce effective solutions.

Multi-function Stainless Steel Compressed Air Filter Regulator For Severe Environments


Industrial processes utilize compressed air and gases for many applications. Maintaining appropriate pressure and keeping the air supply free of particulates is a basic requirement for almost every compressed air system. The Rotork Midland brand of filter regulators are designed to provide both the filtration and pressure regulation functions in a single unit. Additionally, the 3550 series is designed for service in harsh environments with it stainless steel construction. Intended primarily for use in valve actuation air supplies, several versions provide differing pressure ranges, connection sizes, and maximum flow rates. There are options for filtration to the 5 micron level.

Basic data sheets for the units are provided below. All the application assistance you need for your valve automation challenges is available from the specialists at MS Jacobs.

Filtration Yields Returns By Protecting Fluid Process Lines and Equipment

Most people think of "industrial" equipment as super heavy duty, virtually indestructible. Those of us responsible for operating and maintaining industrial process equipment recognize that is not the case. Even the most formidable appearing equipment can be crippled if not protected from the insidious effects of particulates.

There are numerous strategies for mediating the impact of particulates on industrial fluid process equipment and systems. The best solutions will be customized for each process, with consideration given to:
  • Maximum particle diameter threshold: At some level, particulates may be small enough to preclude damage to the system. Above the threshold level, removal of the particles brings some benefit to process operation.
  • Pressure drop associated with any mitigation techniques: Assuming that mitigation will involve the addition of components to the fluid system, minimizing the added pressure drop is advantageous.
  • Overall volume of particulate matter to be removed: Most often, mitigation equipment traps and retains particulate matter. The retaining capacity of the unit must match the particulate production rate of the process. Be mindful that certain events, such as routine maintenance or cleaning of process equipment, may produce surges of particulates in some types of systems.
  • Location of the filtration equipment: Filtration units must be placed in the process flow upstream of the equipment or system portion to be protected. An additional consideration is a provision for maintenance through placement in a convenient, easily accessible location.
  • Filtration equipment materials of construction: The filtration gear must be fabricated of materials compatible with the process media.
I have provided a data sheet below with cutaway illustrations and detailed performance data for one type of filtration unit. This particular equipment is manufactured by the filtration division of Eaton and features a duplex strainer basket arrangement with a diverter valve. The process fluid flows through one strainer, with the other clean and ready to be brought on line when the active basket becomes clogged. When the active basket becomes clogged and pressure drop excessive, the operator moves a lever to divert the flow to the second basket, sealing off the now clogged basket area so that it can be opened and cleaned. This design provides for uninterrupted process operation.

Browse the provided data sheet. You will likely pick up something you did not already know, or get a quick refresh of your technical knowledge. The duplex basket strainer is one type in a wide variety of filtration products available for every conceivable process application. Share your challenges with a product specialist. Combining your process knowledge and experience with their thorough product application expertise will generate great solutions.
