<p>A delivery connector (10), particularly for submersed pumps, which comprises:
- an elbow duct (11) provided in one piece, bent in the shape of an inverted letter U and intended to be arranged vertically,
- a one-way valve (13) to be connected downstream of the elbow duct (11),
- means (14) for the quick coupling of the elbow duct (11) to a hydraulic system. The connector (10) can be used in collection apparatuses (15) particularly for wastewater, which comprise:
- a tank (16),
- a submersed pump (12) in the tank (16),
- a connector (10) that connects the submersed pump (12) to a hydraulic system at the top of the tank (16).</p> |
