ABSTRACT:
In a process for the monitoring of leakage in the hydraulic pressure area of a membrane pump, processing is in a manner such that the point in time (t3), at which the snifting process serving for leakage compensation is initiated, is monitored continuously and compared with a reference value (t1), where a predetermined deviation (Δt1−t3) between two values (t3and/or t1) triggers a leakage display.
