NOTE62
Discharge pressure is the maximum pressure at the pumphead discharge head port that the
pump can provide a flowrate against. Pressure is measured as RMS (Root Mean Squared) gauge
pressure.
20.1.3.1.1 Pressure: limits of operation
All models: Maximum inlet pressure: 2 bar
A qdos30 can be operated at discharge pressures of up to 10 bar (145 psi), however flow rate and pumphead life
will be affected
