• unstable pump curves must be avoided. H total = 3 + 30.58 = 33.58 m. Unless noted, the system resistant curve should be considered a resistant curve not including the static head (or the static pressure) components.

When the pump and system curves intersect at flow rates further away from the bep, especially when outside the por, various problems such as excessive vibration, suction/discharge recirculation, cavitation, low bearing/seal life, and other issues can become prevalent. • the flow for each pump equals half the flow at point 3.

It is important to accurately characterize the system curve to select the correct pump for various operating conditions as the operating point of your system will be dependent on the intersection between the system curve and the pump curve. The reasons why are discussed here.

First, let's discuss the head curve. The curve begins at the point of zero flow, or shutoff head, and gradually descends until it reaches the pump runout point or maximum flow rate.

After all, the system curve determines the operating point on a pump’s performance curve. The reasons why are discussed here.

Note That For Two Pumps With Equal Performance Curves Running In Parallel.

Point 3 is where the system operates with both pumps running; In my opinion, the system curve is the single most important component of the pump selection process. A pump system curve is a “must have” when you are selecting the proper submersible wastewater pump to meet your application needs.

The Pump Characteristic Is Normally.

Since this system does not have active control devices, the system will operate where the pump and system curves intersect, which is at 200 gpm and 296. Point 1 is where the system operates with one pump running; We can combine the system curve with the pump curve to get an overall understanding of how the system will operate.

The Pump’s Operating “Sweet Spot,” Or Best.

System curve generated in aft fathom shows a system that is static head dominated. • zero flow or “shut valve” heads must match for the pumps. The static drop is shown as a straight line on the h axis.

The System Curve Is Half Of The Requirement To Selecting The Right Pump For You.

The system performance curve is composed of a static and. Convert the pressure to the equivalent head of the fluid: Suction piping or an intake structure leading to the pump.

When Plotting Pump And System Curves With Two Or More Parallel Pumps, Aft Fathom Offers Two Methods:

Centrifugal pumps have three zones on their performance curves: When the pump and system curves intersect at flow rates further away from the bep, especially when outside the por, various problems such as excessive vibration, suction/discharge recirculation, cavitation, low bearing/seal life, and other issues can become prevalent. Utilize the system curve and the pump performance curve to select the proper pump for a particular application.
