Floating suction filters
Our filters increase the operational safety of every rainwater system.
They protect the pump from sediment suction. All metal parts are made of stainless steel.
Extraction from the cleanest water layer
The float allows the suction point to rise and fall with the water level. This draws the water from the cleanest area of the cistern. Greasy and light debris collects on the surface of the water, where it regularly drains away via the overflow. Sand and heavy particles collect in the bottom sediment.
Safe function of the pump
The large surface of the floating suction filters has only a low flow resistance and thus ensures that the pump's performance can be fully developed. The rounded, hose-protecting spout with its additional bead ensures permanent function and secure hold of the hose even with frequent up and down movement.
Coarse or fine filtration?
All floating suction filters have a stabilised filter mesh made of stainless steel. You can choose between a coarse or a fine mesh size.
- Fine filters (0.3 mm mesh size) are used for direct water extraction from open waters such as rivers, ponds or wells.
- Coarse filters (1.2 mm mesh size) are suitable for pre-filtered water from cisterns, rainwater storage tanks and other closed containers.
The operational safety of the system is significantly increased by floating suction filters, as pump wear and the fouling of valves are considerably reduced.
Floating suction filters for large systems
Floating suction filters from WISY are available for large systems with up to 2" connection.
The floating suction filters with large connection cross-section are reinforced with additional struts to withstand the volume flow of large pumps.
Available in a set
The connection spout of the floating suction filters is available with an optional non-return valve (=backflow preventer). When using a suction pump, it ensures that a water column always remains in the hose and does not have to build up again every time the pump is started.
Selected suction filters are also available as a set with hose and connection for the submersible pump or PE pipe.

Fixed mounted suction coarse filter with a mesh size of 1.2 mm. Made entirely of stainless steel and with connection threads in various sizes.
Important details
Floating fine suction filters
With a mesh size of 0.3 mm, floating fine suction filters are ideally suited for direct water extraction from open bodies of water such as rivers, ponds or wells.
Product information
Floating fine suction filter
The floating fine suction filter is suitable for sucking in water that has not been pre-cleaned, for example from open water or wells. The floating body allows the suction point to rise and fall with the water level. This draws the water from the cleanest area of the cistern.
