Couplers allow the pump to be extracted and then quickly returned to the tank with no need to drain it, often an expensive operation involving lengthy plant stoppages.
Perfect mating between flange and coupler is ensured on all units in the Zenit range by a rubber gasket.
Zenit bottom couplers can have horizontal or vertical discharge in order to better adapt to the customer's needs. All couplers are designed to receive 2 guide pipes which can accompany the pump into its working position, preventing troublesome rotation.
What's more, a particular system simplifies pump release and reduces the mechanical stresses on the guide pipes, even after an extended period of time immersed in the wastewater.
Another special feature of the Zenit vertical couplers is that they are designed to keep the pump's intake port at the ideal height, with no need to create a step in the bottom of the tank.
They therefore provide a considerable savings in terms of time and the costs involved in the building of collection tanks as well as easy replacement in pre-existing plants.
