  • Patent number: 12472517
    Abstract: A dense-phase powder pump for conveying powder has at least one powder conveying chamber with a gas-permeable filter element that has at least regions thereof accommodated in a casing body and at least one pinch valve that is or can be connected to an end region of the powder conveying chamber. In particular, the dense-phase powder pump has a pinch valve housing formed as the end piece of the powder conveying chamber, which pinch valve housing has a first region facing the powder conveying chamber and an opposing second region, wherein the first region of the pinch valve housing is designed to be connectable to the end region of the powder conveying chamber by means of a plug connection, in particular a sole plug connection, and wherein the second region of the pinch valve housing is designed to exchangeably accommodate the pinch valve.

  • Patent number: 12447485
    Abstract: A powder conveying chamber for a dense-phase powder pump for conveying powder, in particular coating powder, has an end region via which the powder conveying chamber is or can be fluidically connected to a powder line, wherein the end region of the powder conveying chamber is configured as a transition region and designed to reduce an effective flow cross-section of the powder conveying chamber to an effective flow cross-section of the powder line and/or to an effective flow cross-section of a valve arranged between the powder conveying chamber and the powder line, in particular a pinch valve. In particular, a cleaning system is associated with the end region, with which the end region can be supplied with cleaning air in the form of pressurized air, in order to keep the end region free of powder deposits or in order to remove powder deposits in the end region.
