The pump pre-filter is suitable for all common garden pumps, domestic water systems, and home waterworks with a G1 connection thread (33.3 mm) - especially for devices without an integrated filter with a flow rate of up to 6,000 l/h. The filter insert can be removed for cleaning. The mesh size of the fine filter is 250 µm (0.25 mm). The radial PerfectConnect sealing principle of the BP accessories allows for easy installation, seals particularly reliably, and thus guarantees trouble-free operation of the pumps.
