  • First and second pumps in a common housing with parallel flow
    Patent number: 9360010
    Abstract: A pump (1) having a housing (15) with a suction-side fluid inlet (4) and with a pressure-side fluid outlet (5), having a first pump unit (2, 11) and having a second pump unit (3, 12), the first pump unit being connected hydraulically in parallel with respect to the second pump unit, wherein the housing (15) is of modular construction and has a first housing part (3), which houses the first pump unit (11), and also a second housing part (14), which houses the second pump unit (12), wherein the fluid inlet (4) of the housing (15) forms in each case one fluid connection to the first and to the second pump unit (2, 3, 11, 12), and wherein the fluid outlet (5) of the housing (15) forms in each case one fluid connection to the first and to the second pump unit (2, 3, 11, 12).
