Alfa Laval LKIF In-Line Filter
LKIF is a sanitary in-line filter for use in dairies, breweries and other food industries as well as in the pharmaceutical and other light chemical industries.
LKIF is designed for filtering particles from the products, e.g. for protection of pumps and other sensitive equipment.
Working principle
The filter can easily be removed for cleaning without any interference with the process plant.
It is recommended to install the filter so that the inlet flow is as shown in fig.1. The particles will then be accumulated at the inside of the filter which facilitates the cleaning process.
The inlet flow can, however, be in the other direction, if required.
Alfa Laval LKSF Slot Strainer
LKSF has a wide range of applications within process filtering, especially where strainers of hygienic design are required.
Working principle Type LKSF-BL.
The product enters at A. 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. It is also possible to reverse the flow and flush out the impurities (back flush).
Working principle Type LKSF-CL
The product enters the filter at A. Most of the impurities will collect at the bottom and can be emptied via a valve, during operation.
Emptying can also be automatic by means of 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 a minimum of 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 degree of filtering may be changed immediately by changing elements.
Alfa Laval LKVF Coarse Strainer
LKVF has a wide range of applications where removal of particles from a flow is required, eg. for protection of a pump or other sensible equipment.
As options other perforations and mesh sizes are available as well as monel screens. The strainer cap can be drilled and tapped for blowdown and drain valves if required.

Standard Design: Both strainer types consist of a housing in three parts, LKSF-BL has housing in two parts (101.6 mm)(4”) in which the strainer element is placed. The housing is assembled by means of clamps, (the upper clamp ring has a wing nut for manual operation) to allow for quick dismantling for the cleaning. The strainer element is fitted centrally in the housing and has direct access to the end cover of same where a welded on handle facilitates dismantling when cleaning is required.
