PerformanceCurve

The following figure shows the temperature according tomin.flowandratedflow

1.Curve tolerance in conformity with ISO9906 Annex A
2.All curves are based on the measurement byDOOCHstandardmotor
3.Measurement is done within 2 0 % air-free water,kinematicviscosityof1mm²/sec
4.The operation of the pump shall refer to the performancerange indicatedbythethickened curvetoavoidoverheatdue tothelow flow rate or overload of motor due to the large flow rate.

PumpSelections

Selectionof pump,the followingsshouldbe considered. -Usage (Service)
-Maximum flowand pressure
-Comparison of positive suction head

Efficiency

If the pump always runs at a steady start point,a pump should be selected to meet the max. efficiencypoint and start point.Incase thewater consumption is changed,the pump selection should be reconsideredaccordingtothemax.flowconsumption and the consumption pattern.

Min.InletPressureNPSH

If the pressure in the pump is lower than the steaming pressure,cavitationsmight occur.Toavoid cavitations,a minimum pressureat the inlet side of the pump is required.The max.suction head can refer to thebelow figureand be calculated with the following formula;

{ \sf H } = PaX10.2-NPSH-Hf-Hv-Hs

\mathsf { P b } = atmosphere pressure(bar),the pressure can be set1bar.Inaclosedsystem,Pb meanssystem pressure(bar)

NPSH \mathbf { \tau } = \mathbf { \tau } NetPositiveSuction Head (m),itcanbereadoutfrom thepointof possiblemaxflowrateshownonNPSHcurve

Hf \mathbf { \tau } = \mathbf { \tau } Pipeline lossat the inlet(m)

Hv \mathbf { \tau } = \mathbf { \tau } Steaming pressure(m)

Hs \mathbf { \tau } = \mathbf { \tau } Safetymargin,itmeansminimum O.5mdelivery head

If the calculated result H is positive,the pump may run under the max suction head H. If the calculated result H is negative,a pressure over H is required at the inlet side of the pump.
