Our magnetically coupled centrifugal pumps are hermetically sealed and absolutely leak-free due to their non-contact torque transmission. Pumps made of plastic or stainless steel are placed outside of the medium or container and integrated into the plants piping system.
RENNER vertical centrifugal immersion pumps are designed for vertical deployment in non-pressurized tanks, open basins or pits. They offer the same range of services as magnetic drive centrifugal pumps, and enable additional possibilities due to the vertically submerged installation in the container or tank.
Customer-specific adjustments are possible with little to no effort thanks to our modular system. For critical applications, we offer a wide variety of patented waterproofing systems.
RENNER filter units are designed and constructed for deployment in chemical baths and processes. They have proven to be ideal in the circulation and cleansing of clean, slightly dirty or abrasive media, aqueous solutions, suspensions or liquid mixtures.
The RENNER universal filter housings are used to remove organic and inorganic impurities through deep and surface filtration of aggressive and neutral liquids and gases.
All universal filter housings are engineered to also accomodate wound cartridges, activated carbon, filter bags and filter plates.
The line of products SF has proofed to be extremely reliable for use in chemical plants. These filters are characterised by compact design as well as easy and quick handling thanks to the quick fastenings, which notably reduce time for maintenance. All quick change filters are supplied with two safety switches, which prevent the filters from working without or with an open cover.

For industrial solid-liquid separation processes, RENNER offers a wide range of filters. Here the focus is on filter cartridges, bags and paper and adsorption media such as Spaghetti filters, angel hair or activated carbon.
RENNER supplies the necessary consumables for all filter housings.
RENNER offers a wide variety of different filter cartridges for almost any application.Advantages:
The R-CX depth filter cartridge is the premium product among the melt-blown filter cartridges. Only precisely defined microfibers from a special recipe of bi-components are used in the melt-blown process for the production of these 3D-absolute filters.Lenghts:
The microfibres used in the pleated depth filter cartridges are particularly uniform and are thermally bonded to from a homogeneous filter layer. The resulting micropolypropylene filter matrix is considered to be the most effective deep cartridge filter and has the highest efficiency for very difficult to filter fine particles.Lenghts:
The polypropylene mesh filter cartridges is a cersatile reusable filter element made of polypropylene fabric.
It is easy to clean and can be quickly voncerted to other lenghs and/or finenesses using the modular principle with a few components and little effort.Lenghts:
Metal mesh filter cartridges are special cartridge filters made of stainless steel. they are used when plastic filter cartridges are unsuitable, e.g. at high operating temperatures or in connection with certain chemicals as well as in proceses that take place at high pressures. They are also known as surface filters.Lenghts:
Activated carbon filter cartridges are equipped with steam-activated hard coal pellets and are especially designed for heavily contaminated liquids. Due to the bulk form, no blocking of the activated carbon surface by coarse dirt is possible and the period of use is extremely long.
RENNER offers you an extensice range of different activated carbon filter cartridges, as well as activated carbon granulate in AK-canisters. These are used when the pure mechanical filter effect is no longer sufficient for the dissolved substances, as they are only molecular in size.Lenghts:
Filter bags are a widespread alternative to filter cartridges and particularly easy to handle. Because the debris remains inside the filters and when changing the bag the dirt is also eliminated the bag filter housing remains clean on the filtrate side. Key applications include paints and coatings, chemicals and the food processing industry.
Filter paper is a widely used filter medium especially in the electroplating industry. It is available in thin or thick as well as activated carbon versions.
Our filter papers are available in all standard sizes please indicate your desired dimensions in your inquiry.
Adsorption media are a kind of pre-filters based on polypropylene, which are integrated in the actual filtering process. RENNER differentiates Spaghetti filters of microfiber and Angel hair comprising fiber flakes.
The Spaghetti filter comprising microfiber and the Angel hair comprising fiber flakes are polypropylene products, which are simply inserted into the filter chamber or filter bag, and thus prevent clogging of the actual filter medium or, at least significantly delay it.
They are used primarily when very fine particles are present, such as colloids, which would quickly block any filter through a thin fine layer of slurry. Using coarser filter media in such situations would indeed increase the service life and reduce the blockage, but not achieve the desired filtering effect. And enlarging the filter surface would be like expanding the entire filter system, and that would require correspondingly more space and more filter media.
The RENNER Module System would not be the same without a wide selection of pumps and filter accessories. The whole range not only comprises special equipment made of plastic, but also many other items that might be of great use to you obviously made of true RENNER top quality. Do not hesitate to ask advise if you are looking for parts that are not listed up here. We will be happy to help you.
