Multi-basket Bernoulli Filter
In 2013 a new product family was added to the Bernoulli product portfolio, the multi-basket Bernoulli Filters. The multi-basket Bernoulli Filter was developed to meet a market demand for finer filtration in combination with large capacities. This range offers all of the advantages of a single-basket Bernoulli Filter, such as low flushing pressure and constant pressure drop, but it utilizes multiple filter baskets instead of a single filter basket. Put simply, it’s the traditional Bernoulli Filter, multiplied!
The BMG product line
The BMG product line is the first member of the multi-basket product family. It consists of four models, DN 400 (16”) to DN 800 (32”), covering a capacity range of up to 8400 m3/h. Thanks to the use of multiple filter baskets in one filter body, fine filtration down to 100 microns is achievable, even at high flow rates. This means that one single multi-basket unit is capable of doing the work of multiple smaller single basket units. The result is a space efficient installation that requires less piping. Like the single-basket BSG product line, the BMG product line benefits from the use of GRP (Glass fiber Reinforced Polyester) as filter body material, which is the superior material of choice for seawater applications. Since customisation is vital to our business, multi-basket Bernoulli Filters can be manufactured in several steel materials to comply with customer’s specific requirements and needs.
There are two types of filter baskets; perforated or wedge-wire. Our standard filter basket range is made in stainless steel (316L) or titanium but other metals like Duplex stainless steel and Super Duplex stainless steel can also be used if required.
The range of available filtration degrees for each filter size is given in below table.
By using our selection chart below you can select an appropriate filter size corresponding to required flow rate.

The Bernoulli principle
The distinguishing feature of a Bernoulli Filter is a disc mounted on a pneumatic cylinder, which enables contactless cleaning of the filter. The cleaning sequence itself is automatic and continuous, requiring no manual intervention.
