The OASE 20000 pump chamber is ideally matched to the modular OASE Maxima 60 water reservoir system. A closer look reveals the complex functionality of this cleverly designed system element: the lowest part is the deepest part of the chamber. It ensures that the pump is always in the water. The contour of the centre section is precisely aligned with the Maxima blocks, so that the elements can be installed quickly, easily and flush with the seams. The outlet for the hoses is located in the upper section. An OASE three-way distributor or, for automatic refilling with fresh or process water, an OASE AutoFill Kit can be installed here. Small and compact, made of robust material with a high load capacity, the OASE pump chamber 20000 (686 mm × 406 mm × 400 mm) with its 120 litre volume is best suited for Maxima 60 blocks.
