Two phase flow slurry pump, using the theory of two phase flow in the principle of "relative suction, relative block" for hydraulic design of pump, the hydraulic performance of pump flow components comply with the principle of solid-liquid two-phase flow, thereby reducing the slurry flow across parts of wash and wear, greatly improving the work efficiency and service life of pump, this series of pump has the following distinctive features:

1. Efficiency and energy saving: the operation efficiency is 3 to *0 percentage points higher than the average pulp pump, and the energy saving and the consumption of it is *5 to *0%

2. Good cavitation performance and long life: the actual service life is 2 to 3 times higher than that of ordinary pulp pump;

3. High concentration and no clogging: the concentration of conveying pulp can reach 6%;

4. The structure is reasonable and the maintenance is convenient: the head part of the pump adopts the front and rear door structure, which does not need to remove the pipe when maintenance, so it can remove and repair the pump simply by moving the motor backward.
