PIPELINESTRAINERS

A HISTORY OF INNOVATIONHAYWARD® began manufacturing speciality metal valves and industrial flow control products in 1923. Since then, HAYWARD has evolvedthrough strategic acquisitions and technologicaladvances to become the world’s leader in Solidsand Liquid separation.

The HAYWARD Filtration business comprises 3 complimentary technologies; Gas-LiquidSeparators, Pipeline Strainers and Bag and Cartridge liquid filtration systems. With 7 globalmanufacturing facilities, 26 wholly owned subsidiaries and an independent distributor network, HAYWARD Filtration actively servescustomers in over 45 countries.

Building on more than 75 years of Pipeline Strainer expertise, in 1996 HAYWARD diversifiedinto Bag and Cartridge liquid filtration by acquiring American Felt and Filter's Filtration division. In 1998, HAYWARD established itself as a key supplier outside the USA by acquiringGermany’s LOEFFLER® Filter-Technik. In 1999, the acquisition of GAF® Filter Systemsestablished HAYWARD as the world's premiersupplier of liquid bag filtration products.

This brochure details what is regarded as one of the most comprehensive ranges of industrialPipeline Strainers available on the market. Over recent years HAYWARD has introduced

new concepts in strainer design such as the Model 53BTX Ball Type Duplex strainer (See page 3).

With its patented diverter cartridge that provides leak tight isolation, the 53BTX significantly increases safety.

• A dual basket strainer design that allows continuous flow of thefluid during cleaning. No shut down is required to clean the dirtybasket so the process is not interrupted.

• The change over from one basket to another is made by turningthe single lever.

• Threaded connections are provided on the side and bottom ofboth basket chambers so that the process liquid can be completely drained if necessary.

• Large capacity baskets increase operating time and reduce thefrequency of cleaning.

• Double stem O-rings provide positive sealing even under themost arduous service conditions.

• The unique reinforced seats require no adjustment and are designed to provide the longest possible life.

• Piston seal chamber covers with quick open fixings allow thebaskets to be removed quickly and easily for cleaning withoutany special tools.

• The 53BTX will operate effectively without any lubrication of thediverter mechanism, unlike other designs which require regularinjections of grease.

• A low profile design combined with full size baskets allows easyinstallation without compromising the low pressure drop.

• HAYWARD self-cleaning strainers are designed for the continuousremoval of entrained solids from fresh, brackish or salt water.

• They have performed successfully in industrial, power, process, wastewater, paper and municipal applications for over 30 years.

• A comprehensive range of sizes, models and materials is available, to suit various duties and operating conditions.

• Ideal for systems where high flows means that manual cleaning isimpractical and also where continuous flow is required.

• Fully automatic function, complete with a control system that ensuresoptimum cleaning is achieved at all times.

• A small proportion of the screening element is cleaned, whilst theremaining screen area continues to strain. There is no interruption offlow during the cleaning cycle.

• Often installed in remote, unmanned locations, or in hazardous environments where personnel are at risk.

• Commonly used on water service where the disposal of the backwashwater is not a problem.

• Most frequently used to clean water and protect capital equipmentsuch as membrane filters, heat exchangers, pumps and spray nozzles. Ensures the quality and efficiency of cooling water, filterssecondary effluent for use as wash water and provides clean water for quenching and de-scaling in the primary metals industry.

SELF CLEANING

These value added features: Give these benefitsA true backwashing design Ensures the most efficient that returns strained water removal of solids back through the element from inside the element A concentrated high velocity Reduced cleaning times, backwash that sweeps the fewer cleaning cycles and full width of the element in a less waste watersingle pass

Fabricated units are availablewith an ASME Code Stamp. Other materials available on request.

DuraWedge® Element

DuraWedge® is a non-clogging Stainless Steel straining elementconstructed from V-Shaped profile wire.Vertical collector bars form spaces to accumulate debris and dirt andprevent "Ploughing" of this material by the rotating backwash arm,whilst also allowing focused cleaning of the element segment by segment. The V-Shaped profile increases the velocity of the reverse flow during backwash for optimum cleaning, and also helps preventstapling of fibres. The all welded design with reinforcing bands provides structural integrity and significantly increase the operational lifetime of the element.

A rugged and economical StainlessSteel element, made from convolutedplate for optimum filtration area.Reinforcing bands provide added resistance to pressure and flexing, whilst the cartridge design aids removalfor inspection. The convoluted sectionsprovide collection spaces to prevent any "Ploughing" of dirt and debris bythe rotating backwash arm.

Convoluted Element

Backwashing OperationSELF CLEANING

• Dirt laden fluid enters the bottom chamber of the strainer, wherethe velocity decreases allowing larger debris to "Drop out" preven-ting damage of the element. The fluid then flows through the ele-ment - inside to outside. Any dirt or particles present are preventedfrom passing through by the element, and clean fluid flows out ofthe strainer.

• At a set moment, a timer in the control panel switches on themotor that is fixed to the top of the strainer. This motor is connec-ted to the central backwash arm that begins to rotate.

• At the same time, the control panel also sends a signal to an actu-ated ball valve on the backwash outlet causing this to open.

• As the strainer is operating in a pressurised system and the back-wash discharge is now open to atmosphere, the difference in pressure causes a small amount of the strained fluid to pass backin reverse through the element.

• The returned fluid rinses off the debris from the inside of the ele-ment, directly in front of the backwash collector. The backwashwater and debris is carried down through the hollow collector andis discharged to a drain.

• Backwashing continues until the timer reaches its pre-set duration.The control panel then closes the backwash valve and shuts downthe motor simultaneously, returning the strainer to normal strainingstatus.

• A differential pressure switch is fitted to the strainer as a securitydevice, in case cleaning is required between timed cycles. Thismeasures the pressure loss across the strainer, and overrides thetimer in the control panel should the element start to clog or ifthere is a particular incidence of turbidity in the system.

Basket options:

“Y” TYPE

CylindricalStandard baskets with bow-shaped handles which are pushed down bythe cover to ensure a tight seal in the strainer body. This is the standardtype of perforated or mesh basket available in Stainless Steel or Monel.

Pleated (Convoluted)Pleated, open type baskets which have a very low pressure drop. Theconvoluted or pleated structure gives a much greater straining area thenother designs.

Elements (Screens)Used in self cleaning strainers instead of baskets to trap unwanted particles and debris. These items are designed so that debris is easilydislodged during backwashing, and can be made from perforated plate, sinter bonded mesh and wedge wire (DuraWedge®).

Slanted (Elliptical) TopThe slanted open top design allows fluid to enter easily and cuts downpressure drop. This also allows inline connections on fabricated bodies,and also the use of smaller baskets in multi-basket strainers so thatthese can be removed easily by one person, even on very large units.

Basket and Element TypesThe basket or element is the heart of a HAYWARD strainer. After a parti-cular type of strainer housing has been selected, equal concern shouldbe given to the basket or screen design and the perforation or mesh size,for this alone determines the ultimate functionality and performance ofthe strainer.

Strainer SelectionBasket strainers should always be "Sized" to avoid exceeding the maximum permissible pressure drop of the chosenstrainer and basket combination when clean. "Sizing" will determine the pressure loss for a given strainer and basketcombination, and therefore ensure the satisfactory operation of the strainer and also the longest possible service life.Our sales team will be happy to discuss your requirements and select a suitable strainer for you.
