Abstract

The present invention relates to an improvement which applies to all types of centrifugal pumps, particularly those equipped with filters (2) including a body (15), a filter (2), a filter chamber (1), a discharge pipe (6) and a separation partition (8,3) between the filter chamber (1) and the turbine chamber (4), and characterised in that they include at least one calibrated opening between the periphery of the turbine chamber (4) and the filter chamber (1) allowing a permanent water circuit to be set up between the two chambers. <IMAGE>
