PerformanceCurve

1.Curve tolerance in conformity with ISO9906, Annex A
2.All curvesare 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 performanceregion indicatedbythethickened curve to prevent overheatingdue to thesmall flow rate or overload of motordue to the largeflowrate.

The following figure shows the temperature according tomin.flowandratedflow

PumpSelections

Selection of pump,the following should be considered. - Usage (Service)
- Maximum flow and pressure
-Comparison of positive suction head

Note:Piping sizes should be under1.5m/sec.of the liquid speed

Efficiency

If the pump always runs at a steady start point,a pump should be selected to meet the max. efficiency point and start point.In case the water usage changes,a pump should be selected tomeet themax.Qusageandusagepattern.

Min.InletPressureNPSH

If the pressure in the pump is lower than the steamingpressure,cavitationsmight occur.Toavoid cavitations,aminimunpressureat the inletsideof the pump must be guarenteed.The max.suction headcanrefer tothebelow figureandbecaulated with the following formula;

H=PaX10.2-NPSH-Hf-Hv-Hs

Pa \mathbf { \tau } = \mathbf { \tau } atmosphere pressure(bar),the pressure can be set1bar.Inaclosedsystem,Pameanssystem pressure(bar)

NPSH \mathbf { \tau } = \mathbf { \tau } Netpositivesuction head ( \mathsf { m } ) itcanberead out from thepoint of possible max flowrate shown on shown on NPSH curve

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

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

Hs \mathbf { \tau } = \mathbf { \tau } Safetymargin,itmeansminimum0.5mdelivery 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 the pump.
