Basket filter  Manufacturers, Traders, Suppliers

Filter Type W is a very economical strainer:
Its pressure loss is only 50% in comparison to conventional pot / basket strainers and only 25% in comparison to Y-Filters of same dimension and sieve mesh.
This advantage reduces the cost of pump energy and result in extended reserves until the cleaning cycle. Connectors for the differential pressure are standard from size DN 150 and above (below upon request possible).
The streamlined angle of impact between the flow and the sieve / screen results in a slowly increasing pressure loss, caused by dirt, and at least more than double the operational time before cleaning.
As the cleaning cover is located at the top, the rare cleaning cycle is easily and conveniently carried out. The sieve is a closed basket and simultaneously serves the complete removal of the dirt – hence the remaining medium is already cleaned and can be just drained.
Traditional pot or basket strainers are limited by their horizontal installation in pipelines.
In the past, the option to utilise a strainer also in vertical mounting was only provided by Y-Filters – with its given disadvantages of high flow resistance and inconvenient handling of the cover for removal of the sieve (net weight of the cover, overhead work).
The Filter Type W, however, can be installed in both ways – with its given advantages in regards to minimal pressure losses and low frequency of maintenance.
In addition, equipping the Filter Type W with swivel (horizontal) or swing arm (vertikal) provides the maintenance personnel easier handling of the cover and a crane-independent removal of the sieve – with the dirt for cleaning.

Operating pressure: Min.: 16 bar (232.06psi) / Max.: 100 bar (1450.38psi)

Strainers in pipelines have the following function:
Preventing faults and avoiding damaging of existing plant components;
Cleaning of the flowing medium.
These two primary tasks are valid in all areas of application – regardless whether the media are:

• Hot water (district heating systems)
• Cold water (Cooling Systems, municipal applications)
• Hydrocarbons (pumping of oil, petroleum, LNG/LPG)
• Acids or alkalis (chemical plants).

Generally, these tasks are fulfilled by all commercially available filter types, however with high energy requirement and frequent maintenance intervals. Additional cost for shutdown and cleaning could also be reduced.

Overall analysis and solution approach
Minimum €500 Mio. additional cost of pump energy arise in German plants every year!
The reason for this is the installation of common strainers with respective high flow resistance figures (ζ = 3 ... 7 and higher).
The Filter Type W offers with its ζ = 0.7 - 2.3 the solution:
efficient + effective= economical

This filters are used in various fluid processing systems to remove impurities and protect the components of the system. This filters are commonly referred as:
Coarse Filter:
A coarse filter is designed to remove larger particles from a fluid. It is generally the first stage of filtration and is used to protect downstream components from large contaminants. Coarse filters have a relatively high porosity and allow a significant amount of fluid to pass through.
Purpose: They are used to remove larger contaminants from fluids to prevent damage or clogging of downstream equipment. They are common in water treatment systems, industrial processes, and HVAC systems.
Basket Filter:
A basket filter is a type of filter in which the fluid passes through a perforated basket or a mesh lining. The basket captures and holds impurities as the fluid flows through. They are known for their simple design and ease of maintenance; the basket can be easily removed and cleaned or replaced.
Purpose: They are used in a wide variety of applications to remove solid impurities from liquids. They are commonly used in pipelines to protect pumps, valves, and other equipment. Basket filters are versatile and can be used with a wide range of fluid types and viscosities.
Pump Protection Filter:
A pump protection filter, also known as a pump strainer or suction strainer, is a type of filter placed at the intake of a pump. Its primary role is to protect the pump from foreign particles that might cause damage.
Purpose: These filters are crucial in protecting the pump from damage due to debris such as sand, rocks, or other large particles. By preventing large particles from entering the pump, these filters help to extend the lifespan of the pump and maintain its efficiency.
All these filters, although they may vary in design and application, serve the fundamental purpose of removing impurities from a fluid. They are critical components in various systems where they protect equipment from damage due to contaminants, help to extend equipment lifespan, and ensure the fluid that passes through is of a certain cleanliness level. They are integral to maintaining the efficient and safe operation of fluid processing systems.

Common areas of applications are:

• Water treatment plants (pre-filtration stage)
• HVAC systems (air handling units)
• Irrigation systems
• Industrial process lines
• Protection of downstream equipment (e.g., pumps, valves)
• Chemical processing plants
• Petroleum and oil industries
• Food and beverage processing
• Paint and ink manufacturing
• Water treatment systems
• Pump Protection Filter:
• Pump intake in various industries (water, chemical, oil & gas)
• Irrigation systems
• Cooling systems in power plants
• Domestic and industrial water supply systems
