Abstract
The present invention concerns a pump for high-density powder transfer. The pump for high-density powder transportation according to the present invention has four-stroke operation, in which four pumping chambers in reality constitute a system of two pairs of chambers in line with each other. This makes it possible to divide the overall flow rate per minute over four tanks. Each of the four tanks has a reduced capacity, to the benefit of the compactness of the pump and the reduction of the loading/emptying times of the single tank, by exploiting the fluid-dynamic principle of communicating vessels the system of pairs of chambers in line increases the overall powder storage volume, thanks to a constant depression.
