Choose Alfa Laval strainers for reliable filtration, increased efficiency, extended equipment lifespan, and consistent product quality.
How it works
As process fluids flow through Alfa Laval strainers, the filter elements capture solid particles and impurities, protecting product quality and safeguarding downstream equipment, such as pumps, heat exchangers, membrane filtration systems, and cleaning devices, from damage. Only filtered fluids continue downstream.
Once it becomes full, the filter element can easily be removed for cleaning. Certain models also offer automatic backflushing functionality for cleaning without removing the filter element. This reduces manual intervention, simplifies maintenance, and ensures continuous, uninterrupted operation.
Alfa Laval LKIF Inline Strainer
Ensuring hygienic filtration, easy cleaning, and equipment protection
The Alfa Laval LKIF Inline Strainer is an inline strainer intended for process lines in hygienic applications. It provides a safe and economic method to remove particles from liquids in process flows. The filter can easily be removed for cleaning.
Product Benefits
- Hygienic filtration
- Safe and economic method for removal of impurities
- Helps extend product shelf life
- Easy to clean
The LKIF Inline Strainer is designed to remove particles and other impurities from product flows and to protect pumps and other sensitive equipment across the dairy, food, beverage, brewery, chemical and pharmaceutical industries. The LKIF Inline Strainer consists of a perforated filter element with filter ring and seal rings. Optional clamp rings, clamp seal rings, and clamp liner, or DS and SMS unions are available.
How it works
The Alfa Laval LKIF Inline Strainer is installed in process lines and removes particles and impurities as the product flows through the lines. Particles accumulate inside the filter, which can easily be removed for cleaning. If required, the liquid can flow in the opposite direction.
Alfa Laval LKSF Slot Strainer
Providing fine filtration, easy maintenance, and lasting durability
The Alfa Laval LKSF Slot Strainer is a filter which separates solid matter from liquid that flows through it. The impurities are stopped by the filter element. When the filter is full of particles, it can be cleaned by removing the clamp and pulling out the filter element.
Product Benefits
- Fine filtration
- Easy to install
- Easy to clean
- High durability
- Flexible filter element selection
The LKSF Slot Strainer is designed to fulfil basic filtration duties in hygienic applications across the dairy, food, beverage and brewery industries to protect equipment and product.
How it works
Type LKSF-BL: The product enters from the bottom. The filter element captures impurities. When the filter is full of particles, it can be cleaned by removing the clamp and pulling out the filter element. It is also possible to reverse the flow and flush out the impurities (backflush).
Type LKSF-CL: The product enters the filter from the side. Most of the impurities collect at the bottom and can be manually emptied during operation via a valve. Automatic discharge is also possible using two remote controlled valves at B. The upper valve is open during operation and the lower is closed. The impurities will collect between the two valves. Closing the upper valve and opening the lower one will empty the impurities with minimal product loss. The filter can be cleaned as LKSF-BL. The degree of filtering can be altered by changing filter element. Strainer type LKSF-CL must always be installed vertically. The filtration degree may be immediately adjusted by changing the strainer element.
Alfa Laval LKVF Coarse Strainer
Protecting equipment, offering easy cleaning, and ensuring high durability
The Alfa Laval LKVF Coarse Strainer is a type of filter used to remove coarse particles from liquids from 1 to 3 mm.
Product Benefits
- Safeguards membrane filtration, pumps and other equipment from damage
- Easy to install and clean
- High durability
- Flexible filter element selection
The Alfa Laval LKVF Coarse Strainer is designed to remove coarse particles from the liquid flow to protect pumps or other sensitive equipment from damage. It is used on a wide range of applications across the dairy, food, beverage and brewery industries.
How it works
The recommended flow direction is to allow the liquid to enter the inlet (A). The particles strained collect inside the filter element which facilitates cleaning, especially if the handle points downwards or if the strainer is installed in a horizontal position. The liquid leaves the strainer through the side outlet (B).
However, it is possible to allow the liquid to enter the inlet (B) since the perforated tube is designed to withstand the pressure drop in both flow directions. The liquid leaves the strainer through the outlet (A). If side connection (B) is used as the inlet, then the maximum product pressure is 7 bar.
Alfa Laval Mainstream® Strainer and Filter
Versatile filtration for high-flow hygienic applications
The Alfa Laval Mainstream® Strainer and Filter removes particles from process streams with high flow rates, ensuring product quality and hygiene as well as protecting equipment from clogging, fouling and corrosion. This reduces the risk of unplanned downtime and prolongs equipment maintenance intervals.
Product Benefits
- Protects equipment from clogging, fouling, and corrosion
- Maintains product quality and hygiene
- Minimizes pressure drop, even at high flow rates
- Supports disposable and reusable filter media
- Large surface area and side-entry port for efficiency
Versatile and cost-effective, this basket-style filter/strainer with its free-flow design and side-entry ports features a large surface area and side-entry port to handle high flow rates with minimal pressure drop. It is also able to handle a wide range of disposable filter and reusable strainer media, providing maximum application flexibility.
How it works
As process fluid enters the side-entry port of the Alfa Laval Mainstream® Strainer and Filter, it flows through the filter or strainer media, where solid particles are trapped and removed from the product stream. The clean fluid then exits through the opposite side or bottom outlet.
The filter element can be either disposable or reusable, depending on the application's hygienic and operational needs. The large surface area design ensures long operating intervals before cleaning or replacement is needed, minimizing maintenance and ensuring uninterrupted operation.
Alfa Laval Streamline™ In-Line Strainer
Compact, hygienic filtration for smooth and reliable operations
The Alfa Laval Streamline™ In-Line Strainer removes particles from process streams, ensuring product quality and hygiene as well as protecting equipment from clogging, fouling and corrosion. This reduces the risk of unplanned downtime and prolongs equipment maintenance intervals.
Product Benefits
- Ensures hygienic product quality
- Protects equipment from fouling and corrosion
- Minimizes risk of unplanned downtime
- Versatile for use with disposable or reusable media
- Compact, cost-effective, and easy to maintain
Versatile and cost-effective, this filter/strainer with its free-flow design is able to handle a wide range of disposable filter and reusable strainer media, providing maximum application flexibility.
How it works
As the process fluid flows through the Alfa Laval Streamline™ In-Line Strainer, solid particles are retained by the internal filter or strainer media. This prevents contaminants from reaching sensitive downstream equipment like pumps or heat exchangers.
Filter elements are easily accessed for replacement or cleaning, ensuring reliable filtration and reduced maintenance. The design accommodates both disposable and reusable elements, depending on operational needs and hygiene requirements.
