A centrifugal pump pumps fluid containing large or long objects of solid material. Instrument Manifolds Solid parts cause problems with centrifugal pumps in that they both stick to the edge of the

vanes of the pump wheel and get in between the pump wheel and the housing and stick to either one of these may cause the pump wheel to slow down or get stuck. Water Pump Control ValvesLarge parts may

also form a bridge between two vanes. Objects which have become stuck to and rotate together with the pump wheel easily gather more objects and growth of the aggregate is often

very rapid. FILTER SERIESIn all of these cases the flow through the pump is distributed and the capacity of the pump is reduced. These problems are avoided with a centrifugal pump in which

the edges of the vanes (11, 12, 13, 14) extend themselves continuously in the direction of the flow from the input adjacent the shaft and at an acute angle thereto to a lower

part close to the wall (1-1A) of the housing and forwards in the direction of the flow of the pumped fluid.
