Pump performance curves
The delivery head is specified in mwc (metre water column).
1 mwc ~ 0.1 bar
Explanation of the pump performance curve using the
Aquarius Universal 2000 as the example
At the maximum flow rate (Q) of 33 litres per minute, measured
directly on the pressure duct of the pump, the delivery head equals 0 cm.
At maximum delivery head (H) of 200 cm the flow-rate equals 0 litres.
What is the pump performance curve used for?
The pump performance curve, also referred to as performance data,
helps you in correctly advising customers. It shows the relationship
between the flow-rate (Q) and the delivery head (H) of a pump.
Determining the operating point (example)
The pump should displace water 1 m above the water surface. At the
operating point, e.g. on the Aquarius Universal 2000, you can read out
that approx. 18
l/min are displaced (determined theoretically). Small hose
diameter, the hose length and built in curvature can change the value in
the extreme.
