PUMP PERFORMANCE CURVES
The delivery head is specified inmwc (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 perfor-
mance 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 1m above the water sur-
face. 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 extre-
mely.
