Abstract
The invention relates to a multiple-flow liquid ring pump having a rotor housing (1) which surrounds the rotor of the pump and on each of the two end sides of which there is arranged a side shield (2 or 3) which extends at least partially beyond the rotor housing (1) in radial direction, the two side shields (2 and 3) extending in each case beyond the rotor housing (1) at the same point with respect to each other of the circumference, and each side shield (2 or 3) having in its projecting region (corner 16) an inlet opening (7) and an outlet opening (8) on the side facing the corresponding other side shield, in which pump the opposite lying inlet and outlet openings (7 and 8) of the side shields (2 and 3) are connected to each other by connecting tubes (9) that extend parallel to the rotor housing (1), and a suction opening (13) for a feed line and a delivery opening (14) for a discharge line being provided. Such a liquid ring pump is characterized by the fact that it takes up little space and requires only little installation work at the site of installation.
