Abstract: The present invention relates to a pressure boosting system (2) comprising: two or more pumps (4) each having an inlet (6) connected to an inlet manifold (30) and an outlet (8) connected to an outlet manifold (28). The line that connects an inlet (6) and its corresponding connection at the inlet manifold (30) defines an inlet line (» 1 , » 2 , » 3 , » 4 ) and the line that connects an outlet (8) and its corresponding connection at the outlet manifold (28) defines an outlet line (É 1 , É 2 , É 3 , É 4 ). At least two of the inlet lines (» 1 , » 2 , » 3 , » 4 ) are angled relative to each other and/or at least two of the outlet lines (É 1 , É 2 , É 3 , É 4 ) are angled relative to each other. Hereby it is achieved that the pressure boosting system can be very compact.

Abstract: The aggregate has a suction inlet (4) provided on an inlet side of an impeller, and a pressure outlet (12) provided at an outlet side of the impeller. A vortex flow sensor and a guide element are arranged in a pipeline segment formed by the suction inlet and/or the pressure outlet. The guide element controls flow through the pipeline segment. The guide element is formed as a rib (22) inwardly protruding from an inner wall (26) of the pipeline segment. The rib extends in a flow direction (S) of a fluid along the inner wall.

Abstract: The invention discloses a secondary pressurization water supply equipment comprising a base (10), at least two horizontal water pumps (11) mounted on the base (10), a water inlet pipeline, a water outlet pipeline and a controller. The water inlet pipeline includes at least two water inlet components and a water inlet manifold (12), one end of each of the at least two water inlet components is communicating with the water inlet of each of the at least two horizontal water pumps (11), and the other end thereof is communicating with the water inlet manifold (12). The water outlet pipeline includes at least two water outlet components and a water outlet manifold (13), and one end of each of the at least two water outlet components is communicating with the water outlet (112) of each of the at least two horizontal water pumps (11), and the other end thereof is communicating with the water outlet manifold (13). Both the water inlet components and the water outlet components are disposed vertically, and both the water inlet manifold (12) and the water outlet manifold (13) are disposed horizontally. Both ends of each of the water inlet manifold (12) and the water outlet manifold (13) are provided with connecting structures, respectively. The layout of the equipment of the invention is proper, so its structure is compact, the volume is small, and the occupied space is effectively reduced.
