360-D Series Standard Duplex Pump Station

The job of the inlet is to convey the liquid from the inlet pipe to the impeller [...]

When pumps operate away from their BEP, the pumps will generate uneven pressure forces inside the volute casing causing a radial thrust load on the impeller. The radial thrust load has many detrimental effects on the life of the pump. The first and most obvious is a loading on the bearings.

Once we have determined our hatch dimensions, we can then size the diameter of the wet [...]

The Impeller is the heart of the pump in a high flow pump station. It is the only part of the pump that adds energy to the liquid. Grossly simplifying the process, energy is added by accelerating the liquid from the smaller radius at the impeller inlet to larger radius at the impeller exit.

When selecting an electric motor for a pump station, it is important to choose one that can develop enough horsepower to drive the pump.

Many control options are available to system designers these days. We will discuss soft starts, variable-frequency drives, and multiple pump systems.

Jensen Engineered Systems works with UL listed control system integrators to ensure that the control and communications for each project is properly executed.

Selection of the proper type of impeller for your application can have a significant bearing on the applications ultimate success.

We desire high efficiency but also need good reliability and a minimal amount of ongoing maintenance. All of these considerations come into play when selecting the right impeller style.

The purpose of a check valve is to allow a fluid to move through it in one direction, but prevent it from flowing in the reverse direction.

The design criteria that needs to be identified first is the total system inflow rate, and the flow at which the pumps will discharge. As discussed in the pump design section, the discharge flow can be found at the intersection of the system curve and the pump performance curve.

Now that we know our minimum storage volume as well as the size of our wet [...]

So we now know what the minimum volume of the wet well should be to handle [...]

The most important part of any pump selection is determining the operating envelop of the pump. This means we must determine at the very least the required flowrate and head that will be required of the pump.
