The invention relates to a powder pump (100; 100') for conveying coating powder, the powder pump (100; 100') having a powder chamber (10; 10') with a casing tube (1; 1') and a gas-permeable filter element (2; 2') arranged inside the casing tube (1; 1') a first pinch valve (3; 3'), connected to the intake-side end region of the powder chamber (10; 10'), and a second pinch valve (4; 4'), connected to the delivery-side end region of the powder chamber (10; 10'). In order to achieve the effect that the powder pump (100; 100') can be maintained with relatively little effort, according to the invention a first connection element (6; 6') is provided, connected to the first pinch valve (3; 3') and fitted onto or inserted into the intake-side end region of the powder chamber (10; 10'). A second connection element (7; 7') is also provided, connected to the second pinch valve (4; 4') and fitted onto or inserted into the delivery-side end region of the powder chamber (10; 10'). |
