What maintenance do booster pumps require (BPE / BPP)?
Kärcher booster pumps electronic and booster pumps with pressure tank are maintenance-free. We recommend checking the pipe connections at least once year to ensure there is no loosening or leakage.The filter of the pump prefilter should also be checked regularly for soiling and cleaned of any visible dirt. In the case of the BPP booster pumps we recommend checking the pressure of the air in the storage tank at least once a year (target value 1.8–2.0 bar).
