5.2 Technical data
Outline and pipe dimensions (Fig. 4).
5.3 Scope of Supply
• Multistage pump.
• Installation and operating instructions.
Maximum operating pressure
Pump casing
16, 25 ou 30 bars depend on the model
Maximum suction pressure
10 bars
Note : real inlet pressure ( pressure at 0 flow delivered by the
pump must be below the maximum operating pressure of the pump. In
case of exceeding maximum operating pressure, the ball bearing and the
mechanical seal could be damaged or lifetime could decrease.
P Inlet + P at 0 flow ≤ Pmax pump
See pump nameplate to know the maximum operating pressure: Pmax
