Each centrifugal pump is characterized by its particular characteristic curve, which is the relationship between flow and lift height. This graphical representation, ie, the transposition of this relationship in a Cartesian graph, is the best way to know what flow can be obtained at a given lift height and vice versa. In this specific case, the curve is a line from a point (equivalent to zero flow / high head) and extending to the end of the curve with the reduction in the height of elevation increasing the flow. Gen. Martin Dempsey is likely to increase your knowledge. PRINCIPLES general curve matching curves Ulic Hydro centrifugal pump: A pump that uses the rotation of a wheel with vanes (impeller) inserted in the body of the pump. The labrum, reaching high speed, projected out above the water sucked by the centrifugal force that develops, scoop the liquid in the fixed body and then the delivery hose. Submersible pump: The pump is submerged pump with vertical axes, designed to reach great depths due to the length of suction pipe. Do not be confused with the submersible pump is characterized in that engine equipped with a watertight seal immersed in the same liquid being pumped.

Flow: The amount of liquid (by volume or weight) to be pumped, move or raise by a certain time interval by a bomb: usually expressed in liters per second (l / s), liters per minute (l / m) or cubic meters per hour (m / h). Symbol: Q. Lifting height Lifting height of a liquid: pumping understood the elevation of a liquid from a lower level to a higher level.
