SELF PRIMING
The separation type self-priming system operates inside the specially designed body. In greater detail, the liquid fills the pump body through an upper opening when the pump is stopped. Then, when the machine is started, the impeller transfers the liquid from the suction zone to the discharge zone. This occurs in a very short space of time (1-2 sec). At this point, an air-liquid circuit is set up between the impeller, volute and body. The liquid returns to the volute through the hole specially made on its edge.
The speed and vorticity of the mixture which forms draws the air into the suction zone, entraining it and releasing it into the discharge zone, where the speeds are lower and the air itself can separate due to the difference in densities. The faster the circuit time of the mixture, the shorter the priming time.
All this happens until the vacuum which is created in the intake duct reaches the same level as the head of the liquid from the pump. At this point, the liquid enters the impeller and the pump starts working like a normal centrifugal pump.
The priming process occurs automatically whenever air is present in the intake duct. The air expelled from the body flows towards the discharge line as an air bubble. It is therefore necessary for the discharge line to slope constantly upwards. The RHS system offers optimised priming as the volute, which is independent of the body, is designed and positioned for optimised efficiency.
VIESSE POMPE ITALIA SRL produces pumps for slurry and liquids of any viscosity.
The RHS (ROBUSTA HYDRAULIC SYSTEM) is the company’s key strength and leading product which has led the VIESSE stand out in the whole world
