The model 1260 self-cleaning strainer provides a highly efficient and reliable means of removing solids from process fluids. A bank of WEDGEWIRE straining elements provide positive straining. The exclusive WEDGEWIRE straining elements are designed with a unique “v” shape to promote free flow of the incoming liquid and to discourage wedging of any particles. Normal flow is from the inside to the outside of the straining elements and backwashing is accomplished by the reversal of the flow through the elements. The wedge wire straining elements are arranged to accumulate debris on the inside. A rotating arm, which is vented to atmosphere, isolates each WEDGEWIRE element for cleaning. Cleaning is accomplished by taking advantage of the system pressure and the use of a small portion of the system flow. When a WEDGEWIRE element is isolated, an effective backwashing action is created without disturbing total flow. Accumulated debris is flushed out of the WEDGEWIRE element through the backwashing arm and to the drain.

The model 1260 self-cleaning strainer can be arranged for either continuous backwashing or, with the addition of a variety of optional control packages, intermittent backwashing.

The model 1260 self-cleaning strainers are capable of handling flow up to 32,000 USGPM and straining as fine as 0.0025 inch. With reduced maintenance budgets the automatic self-cleaning strainer will help compensate for fewer personnel on the crew.

Tate Andale Model AL and AH Spray-Type Self-Cleaning Strainers arer ecommended for severe operating conditions where the quantity and nature of the debris is such that the standard self-cleaning design is inadequate for effective removal of debris from the surface of the basket. This Variation of the Standard Twin Strainer consists of a spray pipe (Either Fixed or Gearmotor-Driven) located in the center of each basket. Unlike the manual version, liquid flow Is from outside the basket, inward.

To clean a basket, the compartment is isolated by means of manual or electric motor-driven valves, and the drain valve is opened. High-pressure water is then admitted to the spray pipe. The spray pipe nozzles direct jets of water against the inside of the basket, blasting free the debris collected on the outside basket surface. The debris is flushed away through the open drain.

Water for the spray pipes can be taken from the strainer discharge provided the pressure is 50 psig or higher, or from a separate source. There must be no back pressure on the drain line, and the line must be large enough to keep the compartment drained. These strainers are suitable for vacuum or positive pressure operation.

The model AL is a cast, gate valve duplex strainer offering bank vault construction and quality. Designed for longevity, the model AL has only one set of moving parts—the gate valves. These sliding valves have wedge seating, meaning they are wedged to the body when in the closed position. Therefore, the valves do not come in contact with the body during the chamber change over process, virtually eliminating wear. The body walls are the thickest in the industry, providing decades of service. Easy operating features include quick opening covers, cover-lifting davits, and interlocking chain drive on the valve hand wheels, allowing both valves to operate with the turn of one hand wheel. And with the lowest pressure drop available, it becomes the least expensive strainer to operate. The outstanding longevity of the model AL plus its low operating expenses com bine to give you a strainer with the lowest life cycle cost available.

It can also be designed to meet any budget requirement through use of carbon steel (available with fusion bonded epoxy coating) to exotic alloys, from ball valves to butterfly valves. The DU - 200 provide cost efficient operation as well. From quick opening yoke type covers, to cover lifting davits, to backflushing and blow down, it reduces maintenance time and costs. If you want a strainer that's versatile. Plus, easy to own and operate, you can feel confident choosing the DU - 200.

Model ID duplex strainers are engineered for reliability and durability. The tapered plug valve, which diverts flow from one basket chamber to the other, has been designed to "lift" during the change-over process. This virtually eliminates all wear on the plug and body. Reversing the lifting operation reseats the plug, minimizing fluid bypass. The heavy duty castings are the thickest available, providing the highest corrosion allowance and longest life of any plug-type strainer. Designed with straining ratios of up to 15:1, the model ID is one of the most economical strainers to operate. When you factor in purchase and operating expenses, plus longevity, the model ID delivers the lowest life-cycle cost of any plug-type strainer in the industry.

Tate Andale model R and S twin strainers differ from the other twin strainers in the Tate Andale product line in their basic design. The model R and S units feature bodies with a low profile.
