Strainer Selection Guide

Single Basket Strainers
Simplex strainers offer a rugged reliability and a level of versatility unmatched in the industry. From basic cast iron with bank vault quality to truly customizable fabrications, there are options available to meet any operational need as well as fit any budgetary need. Simplex strainers cost far less to operate than Y strainers. Typically, simplex strainers have been designed with open area, or straining ratios, of at least 6:1. On the other hand, Y strainers usually have a 2:1 straining ratio. This means the basket in a Y strainer will fill at least three times as quickly as a simplex strainer, making it three times more costly to operate than a simplex strainer.

When you factor in the outstanding longevity of simplex strainers achieved by their heavy duty designs, plus their ease of operation and maintenance, the total cost of owning and operating these strainers over their lifetime (life cycle cost) is the lowest in the industry. If you want a strainer that’s still operating after all others have failed, you want a Tate Andale simplex.

Single basket strainers are used for batch operations where the liquid flow may be interrupted periodically for cleaning. They are generally recommended for intermittent service such as fluid system start-ups, emergency protection and light duty where the amount of foreign debris is small.

Twin Basket Strainers
When evaluating duplex strainers, the consideration should be focused on both performance and the total cost of owning and operating, known as life cycle costs, of the strainer. The design of Tate Andale’s duplex strainers are uncompromised by an accountant’s pencil. The thick, heavy body walls provide unparalleled corrosion allowance. The straining ratios are some of the highest available. The moving parts are designed to minimize wear. Available wedgewire baskets are the most durable straining elements on the market. All of this adds up to produce the longest lived, most cost efficient, high performance strainers available. Tate Andale strainers may cost more than our competitors, however, spreading this cost over a life expectancy measured in decades, not years, demonstrates that the competing products cost more over the long-term. The high straining ratios, aside from the performance benefits, contribute lower operating costs because the baskets do not need to be cleaned as often. In analyzing the life cycle costs of Tate Andale strainers versus the competition, our designs provide the lowest life cycle costs in the industry.

Self-Cleaning Strainers
Tate Andale self-cleaning strainers are designed with performance being the utmost priority. Offering high straining ratios from traditionally accepted basket designs, these strainers can reduce operating costs due to longer cycle periods when used in the intermittant/ automatic backwash mode. The basket design should be the major concern when evaluating self-cleaning strainers. Quite often artificially high straining ratios are achieved by “unusual methods” such as “accordianed” elements. While these elements may technically possess a higher amount of open area achieved by folding the perforated plate into the shape of an accordian, the resultant valleys will clog with debris twice as fast. Tate Andale basket elements have legitimate open area, whether using highly durable wedgewire or perforated plate. From the cast units to the customizable fabricated units, Tate Andale strainers offer a design that translates directly into longevity and durability. 
For the strainer of a lifetime, select a Tate Andale.

Tate Andale Straining Media

Perforated Plate
Perforated plate is the most commonly used media for basket type strainers and is available in perforation sizes 1/32" to 1/2" diameter depending on the degree of straining required and size and type of basket. Perforations are normally made on a staggered pattern for maximum open area and strength.

Wire Cloth
Woven wire cloth with a perforated backing sheet, is available where a finer degree of straining is required, e.g. lubricating oil service. Wire cloth is available for particle retention as small as 10 microns. Special attention is given to the fabrication of lined baskets to prevent by-passing of debris.



Wedgewire (Well Screen)
Baskets of wedgewire construction are available when additional strength is required for fine straining and for backflush type baskets with fine straining requirements. This additional strength creates greater resistance to collapse when flow is reversed for cleaning. Slot widths are available from 0.001" to 0.5"
