Abstract (en)
[origin: WO2008071592A1] A hydraulic pump (10), of the type which comprises a jacket (11) for containing an impeller assembly (12), which is closed at its ends respectively by a closure head (13) and by a pump body (14) for connection to the hydraulic system. The pump body (14) comprises a footing (17) from which two mutually opposite flanges (18a, 18b) for fixing the pump to the hydraulic system protrude monolithically with respect to the footing ( 17). A box-like body (21 ) is arranged on the footing (17) and forms internally two mutually isolated chambers (22, 23) which are open upward, respectively a first chamber (22) for sending fluid into the impeller assembly (12) and a second chamber (23) for collecting the fluid that arrives from the impeller assembly ( 12). The pump body ( 14) further comprises two sleeves (29, 30), a first intake sleeve (29), which protrudes from the first chamber (22) and is associated at one end with a first one (18a) of the flanges, and a second delivery sleeve (30), which protrudes from the second chamber (23) and is associated at one end with the second ( 18b) of the flanges. The space formed by the contour of the footing (17) which is comprised between the jacket ( 11) and the flanges (18a, 18b) and is occupied by the sleeves (29, 30) is open upward.
