The Oase Aquarius fountain set Classic range is designed to provide excellent flow rate and water pressure output while consuming less energy. These pumps feature a selection of three separate nozzles that can produce unique aesthetic effects, as well as a telescopic riser that can be easily adjusted to suit the depth of the pond. Additionally, the pumps come with a secondary outlet with mechanical flow control that can divert some of the water flow elsewhere.
 
The pump's dimensions are length 205mm, width 180mm, and height without riser 140mm. The length of the telescopic riser is 160mm - 290mm, and the length of the nozzle is 110mm. The total height of the installed unit is 410mm - 540mm (approx.), and the secondary outlet hose connection is 13mm/19mm/25mm (½” / ¾" / 1”).
