6. Performance charts of the QF 150S
Testmedia:
Water at ambient temperature
Type of eccentric shaft: 5°
Discharge pressure:
0 to 6 bar (0 to 87 psi)
Shows approximate flow rates as function of pump rpm.
Please note:
Motor is directly coupled to pump: Pump rpm = motor rpm
The flow rates showing at the chart above were ascertained with new diaphragms and new valves
under standard conditions after the final assembly of the pump.
