Multiphase pump DAF1. Introduction
Multiphase pump DAF is a kind of new DAF pump. It doesn't need air compressor and air saturation tank by using air mixing pump such as Japanese Nikuni pump and Germany Edur pump.
2.Application
1) Paper and pulp industry
2) Petro-chemical industry
3) Oily wastewater
4) Slaughter house industry
The air and water are inhaled by the multiphase mixture pump at the same time, and the air is dissolved into the water by high speed rotating impeller, then the gas-liquid mixture proportion is adjusted according to the site circumstance to achieve plenty of micro bubbles, which are enough to float the suspended matters. The gas proportion in the gas-liquid equilibrium vessel can reach up to 30% at the best state. The micro bubbles from the air releaser is less than 30um, they stick to the suspended solids and float the surface and then scrapped by the skimmer.
