Replacement
In an industrial basket-type strainer, it is the screen that does the work, not the housing. It clogs, it tears at the seam, or it has become too coarse for a new task. What gets replaced are the strainer elements – the strainer stays where it is.
We manufacture strainer elements, strainer baskets and support baskets to size or to sample, for our own units as well as for strainers of other makes. Whether a stainless steel strainer basket, a replacement element or a multi-part element: we do not need an article number for this.
For which units
This means strainers in which a basket or element is inserted into a housing from above and can be removed through a cover. Whether the unit comes from us makes no difference.
The classic basket in a pot-shaped housing. Usually the complete element including fine mesh screen is replaced.
Compact design, often with a conical element. Here the screen sits more tightly in the housing – the seating has to be exactly right.
Two chambers, two elements. It makes sense to replace both together so that the service lives run in parallel.
Cylindrical element in the run of the line. What matters is the length and the design of the seating at the cover.
We also continue to manufacture baskets and screens for our discontinued pot type strainer series – new units are no longer available for it.
Designs
“Replacement screen” stands for very different parts. Which design is right depends on how finely the medium is filtered and how often cleaning is to take place.
A perforated plate basket takes the forces, the fine wire mesh lies on the inside or outside. The most common design, because it filters finely and still withstands pressure.
For coarse retention. Robust, easy to clean, insensitive to knocks during removal.
A base basket with an exchangeable inner screen. If only the fine part wears, only that part is replaced.
More filter area in the same installation space. Useful when a plain screen clogs too quickly and the service life is not sufficient.
Perforation and wire mesh
A screen that has to be cleaned every two weeks is not a good screen. Often this is not due to the strainer but to a mesh size that was chosen finer than necessary.
With the replacement you can correct this: we supply the same design with a different perforation. The only condition is that the element retains what has to be retained. We discuss this beforehand.
Think ahead when replacing
A replacement element is the opportunity to change something that was missing on the old part. Without any modification to the housing.
They retain ferritic abrasion that no wire mesh can capture – metal chips from pumps, scale from pipelines.
Makes it easier to pull the element out of deep housings. On the old part it is often missing because it has broken off.
Coarser if cleaning is needed too often. Finer if particles get through that should be retained.
An exchange element shortens downtime: remove, insert the new one, clean the old part at leisure.
Four details are enough. Outside diameter, height, mesh size and material – taken from the old part. A photo also shows us the design of rim and bottom. How to take the dimensions is explained on the overview page: What we need for a replacement screen →
Frequently asked questions
If the dimensions are right, yes. What matters is the outside diameter, the height and the design of the seating – that is, the rim with which the element sits in the housing. We take these three from the old part or from your details.
Yes. If only the inner screen is worn and the base basket is in order, we manufacture only the inner screen. Send both parts as a sample, then they will be sure to fit together.
That is the normal case in the replacement business. We replicate to size or to sample – more on the page Replacements for other makes.
That depends on the medium and on the cleaning. Mechanical failure is rare; what ends the life of elements is usually cleaning with unsuitable tools or a solid that abrades the wire mesh. Both can be countered with a sturdier design.
Yes – the support basket in which the bag hangs is a classic spare part. We supply the matching bag itself as well.
Send us the outside diameter, height, mesh size and material – or a photo of the old part. For units from our own production, the model and nominal size are often enough.
