Basket Strainer

Strainers – Basket Strainer also known as Simplex Strainers. Basket Simplex Strainers and Filters are normally used for batch operations where the liquid flow may be interrupted periodically for cleaning purpose or other maintenance. They are also known as Inline Simplex StrainersTRISTAR make strainers are widely used across industries for effective filtration of suspended impurities or solid particles from fluids such as oils, fuels, acids, solvents, water etc. These strainers operate on mechanical solid—liquid separation technique, where practically no energy is used.Strainers ensure smooth flow of fluids , protect pumps, nozzles, valves, heat exchangers, control systems and other expensive pipeline equipment thereby ensuring long productive life of equipment. In the process increasing productivity by reducing maintenance and downtime. Simplex Basket Strainers provide higher filtration area as compared to “Y” type or “T” type strainers, hence the frequency of cleaning is reduced.Application Tristar Basket Strainer can be used for filtering a wide variety of industrial fluids such as:

Tristar Strainers are available in two configurations.Inwell Design with multiple elementsIn this type of Strainer the fluid flows through the inlet into inwell chamber from where it enters the filter elements. For designs upto 100 NB we offer single basket element, 100NB to 200 NB two elements and for sizes above 200 three basket elements. As there are more no of elements the Gross filtration area is more compared to single basket element of same size.Direct Element DesignIn this design the fluid directly enters the basket and flows through the outlet. This is a much simpler design and also the pressure drop here is at its minimal. Tristar make strainers are ideal for use as line filters for pipelines of various sizes and process equipment’s with the following unique advantages:Note: Both are Available in Single and Multiple elements

Jacketed Strainers Filters
Jacketed strainers are used for applications where materials must be kept at higher temperatures to keep the Fluid in flowing condition. The strainer body temperature is maintained by circulating steam or thermic fluid through the strainer jacket. The strainer body is provided with a jacket which is welded to the strainer body as integral part. The jacket is insulated to minimize the heat loss to atmosphere.

Sanitary Filter
We design and manufacture sanitary filters to be used in Dairy, Food, Beverage, Cosmetic, Dairy, and Pharmaceutical Industries. These filters are used where hygiene is crucial importance. Sanitary design requires easy to open and clean the filter completely, there should no dead spots where material can accumulate over a period of time and may give rise to contamination. Material of construction is SS 304 or SS 316. The gaskets provided are based on your application you can choose between PTFE or Silicon. These filters are available in inline or side entry/ offline design, depending on your process piping you can choose the best for your application.Our filters are buffed and passivated and are ready to use at site. Depending on the your requirement we can offer the finish.
Stainless Steel SS Filters
Stainless steel filters are used where rust or other contamination caused by MS cannot be tolerated. They are manily used for sanitary applications. We design and manufacture SS filters to suit your application. To design a filter we will require to know the flow rate, operating pressure, filtration size required in microns.

Magnetic Filters
Tristar magnetic filters are designed to capture ferrous particles in the utility or process line. These filters can be designed to use Low Intensity magnets of 2500 Gauss or High Intensity Magnets of 10,000 gauss . Along with the magnetic rods filter element of required micron size is provided for maximum filtration. These filters also known as Rust Capturing Filters.The magnets are inserted in SS 304 or SS 316 tubes and are optimised for highest efficiency. Magnetic rods may contain hard ferrite ceramic magnets or high intensity rare earth magnets. Low intensity magnetic rods are ideal for catching materials such as Nuts, Bolts, Screws, broken washers etc. these rods are designed to attract larger iron pieces from relatively larger distance. High Intensity magnetic rods are capable of catching contamination particles as small as 1 microns. These rods have been designed to attract super fine particles from the carrier material. Based on the flow rate and pressure the filter is designed to ensure all liquid passes through the magnets for optimum filtration.
Cooling Tower Filter
Almost all process cooling systems use water for the purpose of heat transfer. The water over a period of time accumulates dust, sand, pollen, algae, and pipe scale particles. In extreme cases, particle build-up clogs entire systems, requiring shutdowns, expensive maintenance, repair, or replacement. A build-up of solids inside piping can reduce heat transfer, drastically reducing efficiency and increasing energy consumption. Filters are used in the system to arrest the contamination and ensure the efficiency of the equipment’s is maintained. Tristar manufactures filters which help capture these contaminants and ensure your equipment runs to maximum efficiency. Our cooling tower filters are custom built to suit flow rates and pressures of the system.
Y Type Strainers
Y-type strainers are installed on the pipelines to trap dirt , scale, foreign particles, welding debris etc which can cause damage to pumps, meters, valves or other inline equipment’s. “Y” Type strainers are called so because of their shape which looks like a “Y” . They can be installed in either position vertical or horizontal as long as the flow markings as mentioned on them are maintained. These are used across industries in utility and process lines. Tristar Y Type strainers are available in casting as well as fabricated to suit your application. Generally they are of Cast steel with SS304 Perforated sheet and filter element. Filter element can be provided as per your requirement.
T Type Strainers
Almost all process cooling systems use water for the purpose of heat transfer. The water over a period of time accumulates dust, sand, pollen, algae, and pipe scale particles. In extreme cases, particle build-up clogs entire systems, requiring shutdowns, expensive maintenance, repair, or replacement. A build-up of solids inside piping can reduce heat transfer, drastically reducing efficiency and increasing energy consumption. Filters are used in the system to arrest the contamination and ensure the efficiency of the equipment’s is maintained. Tristar manufactures filters which help capture these contaminants and ensure your equipment runs to maximum efficiency. Our cooling tower filters are custom built to suit flow rates and pressures of the system.
Suction Diffusers
Tristar suction diffusers are installed at the inlet of the pump, they serve 2 main purposes .1. To filter debris / foreign matter present in the liquid which may damage the pump over a period of time. 2. To ensure uniform flow to the pump suction. The stream straighteners inside the suction diffuser break the turbulence in water / liquid and stabilize it. Uniform flow ensures the pumps run efficiently and do not cavitate. Tristar Suction diffusers are custom designed to suit the pump requirements for flow and filtration. We can provide the same in Stainless Steel construction or Mild steel as per your requirement.
