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.

Abstract: A cyclonic valve for cleaning pumps for transferring powders of any type in high density, including an inlet duct for introducing a flow of cleaning fluid, a flow dividing element adapted for dividing the flow in inlet into a plurality of flows, and a flow orienter having means for deviating and orienting in space the plurality of flows so as to give each of the flows a tangential motion component with respect to the direction of the flows, and then conveying the flows into one or more ducts towards the device to be cleaned, so as to generate a single cleaning flow in outlet having helical motion.
