The ZO flange is a mounting flange made of aluminium allowing for assembly and disassembly of the drive unit „motor-pump“ outside the tank.
The mounting flange facilitates maintenance of the drive unit, since expensive preparations (e. g.: draining the oil tank, etc.) are eliminated. The ZO flange is available from stock in sizes ZO160 to ZO350.
The set of gaskets (DZ and DP gasket) made of NBR can be supplied.
