Waste water pumps can be fully submergible units. The pump assembly and motor are often separated from each other by an oil fore-chamber sealed by mechanical seals. Any leaks in the shaft seals need to be registered in order to prevent malfunctions or failure of the motor and to arrange for inspections in good time.
BARTEC’s electrode line bushings Ex + sealed allow signals to be reliably transmitted through the walls of pressure-proof enclosed operating equipment, even in areas in which an explosion hazard exists. Only electrical circuits certified as intrinsically safe may be connected to the electrode line bushing.
