The flow rate (Q) of a centrifugal pump is the useful volume flow delivered by the pump via its outlet cross-section (see Pump discharge nozzle). Volume flow rates which are tapped upstream of the pump's outlet cross-section for other purposes (e. g. bypass) must be taken into account when calculating the pump's flow rate. If the fluid handled is compressible, a conversion must …

Centrifugal pumps are used frequently in multiple pump installations where the pumps are piped to the same suction and discharge lines. The combined flow rate is the summation of the individual pump flows at the same TDH. In parallel operation the capacities for each pump are added at any given head.

The durability of the centrifugal slurry pumps allows them to be used for a wide range of industries and are preferred for low viscosity liquids and high flow rates. DAE Pumps provides a variety of centrifugal slurry pumps in multiple shapes and sizes.
May 22, 2019 Centrifugal pumps are devices that are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an electric motor or steam turbine (in case of turbine-driven feedwater pumps). Centrifugal pumps are used in more industrial applications than any other kind of …
This curve, shown in figure 4, represents the characteristics of the piping system to which the centrifugal pump is applied. The head required at zero flow is called the static head or lift. Fig. 4 System Curve This shows how many feet of elevation that the centrifugal pump must lift the fluid regardless of the flow rate.

Centrifugal pumps are used to induce flow or raise a liquid from a low level to a high level. These pumps work on a very simple mechanism. A centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. The two main parts that are responsible for the conversion of energy are the impeller and the casing.
