Axial flow pump and mixed flow pump pipeline configuration requirements

1. Pump inlet center distance from the wall should be inhaled flare diameter D of 0.1 to 1.25 times the suction pipe from the bottom of the pool should be suction horn diameter D of 0.7 to 0.8 times the adjacent two suction inlet The distance between the centers should not be less than 2 to 2.5 times the diameter D of the suction horn tube.

2. The discharge line should be equipped with check valve (or pat door). Pump outlet should be installed between the check valve diffusion tube. Diffusion tube length should not be less than the size of the pipe diameter difference of 5 to 7 times.

3. Spiral shell mixed flow pump should be carried out by centrifugal pump.
