Abstract
The present invention relates to a gear pump having a housing that has an inflow for the liquid to be conveyed, that has an outflow for the conveyed liquid, and that has a pump chamber in which the gear or gears for conveying the liquid are present, with at least one bearing position being present in the housing, in which bearing position at least one gear is rotatably received, wherein the inflow is in a different plane than the outflow; and wherein at least one first flushing passage that extends up to the bearing position(s) is in direct or indirect fluid communication with the inflow and/or with the outflow.
Claims12
A gear pump having a housing that has an inflow for the liquid to be conveyed, that has an outflow for the conveyed liquid, and that has a pump chamber in which gear or gears for conveying the liquid are present, with at least one bearing position being present in the housing, in which bearing position at least one of the gears are rotatably received, characterized in that the outflow is in a plane and the inflow is in a different plane than the outflow;
- and in that at least one first flushing passage that extends up to the bearing position(s) is in direct or indirect fluid communication with the inflow and/or with the outflow, and characterized in that, in a state in which the pump is vertical and in which the inflow and the outflow extend horizontally, the pump chamber is located at the level of the inflow and the outflow is located below the level of the inflow.
A gear pump having a housing that has an inflow for the liquid to be conveyed, that has an outflow for the conveyed liquid, and that has a pump chamber in which gear or gears for conveying the liquid are present, with at least one bearing position being present in the housing, in which bearing position at least one of the gears is rotatably received, and with a magnet for driving the gear or gears being located in the housing, characterized in that a flushing passage that extends up to the magnet is located on the pressure side of the gears, and characterized in that, in a state in which the pump is vertical and in which the inflow and the outflow extend horizontally, the pump chamber is located at the level of the inflow and the outflow is located below the level of the inflow.
