APPLICATIONS

These filters have a removable filter basket. They are used for civil and industrial applications, in pumping systems for wastewater treatment, cooling water, pre-filtration, process water and for installation in front of the pumps to prevent coarse solids from clogging and damaging the impellers.

CONSTRUCTION

The filters with removable filter basket are made entirely of stainless steel 304 or 316.
The AP models can operate at a maximum working pressure of 8 bar, while all other models can operate at a maximum working pressure of 3 or 6 bar. In TF models, the untreated water flows into the filter basket; all other models have the water inlet directly into the filter basket. The inlet and outlet connections are threaded ports ISO 228/1 or loose swivel flanges PN10. There are two welded sleeves in the lid and at the bottom for venting and for draining the filter. The lid is closed by means of a V-clamp with a lever. For all models, locking is very simple and effective. After manufacture, all filters are pickled and passivated.
These unique filters are designed to provide performance over a long service life with minimal maintenance. A true economic answer to liquid filtration. By installing adequate filtration systems, one could realize significant cost savings.
