RF200R Self-cleaning Strainer
Description
RF200R Self-cleaning Strainer
Rotorflush RF200R self-cleaning strainer provides protection against blockage for surface mounted pumps and other connected equipment. These are coarse screened stainless steel dirty water suction intake filters with a capacity of up to 220 litres / minute (14 m3 per hour), capable of filtering from 1mm to 6mm.
The RF200R strainer can be fitted with 1mm or 2mm woven stainless steel mesh, or 3mm or 6mm perforated steel. Both versions are very strong, low maintenance strainers, requiring only the occasional jetwash to keep them running.
These filters use a proportion of the pump’s output to supply a feed to an internal backwashing rotor. This supply is taken off the already filtered pump output. The twin jets of the cleaning rotor rotate at about 60 rpm in each filter, clearing the whole screen every ½ second. As the cleaning mechanism is on the filtered side of the screen debris in the water will not obstruct the mechanism.
Approximately 10 -20% of the pump output is required to supply the cleaning rotor.
For a larger capacity (up to 1000 litres per minute) please consider our RF400AR self-cleaning filter – up to 1000 litres per minute. All our filters and strainers use the same patented technology, providing efficient self-cleaning backwash to keep their filter mesh clear for a range of flow rates.
Alternatively, where your pump output is variable or your pump has a variable speed drive you may wish to use RF-AE & RE series filters with backwash pumps.
