13.3 Coolant monitoring.
A supply reservoir must be assembled here. Level monitoring must be provided in this reservoir. If the
level falls, this is a sign that one of the seals is leaking.
Only when pumping volatile liquid. (Only with Cat. 2 pumps)
13.4 Overpressure protection.
Here on the pressure side of the pump a sensor must be fitted which signals a too high pressure in the
pump housing. This is only required when pumping volatile liquid and/or dangerous liquid.
Set the sensor to 10% above the peak in the original pump curve. (Only with Cat. 2 pumps)
13.5 Underpressure protection.
Protect pump against underpressure. The maximum suction head depends on the NPSH value shown on
the pump curve. Only when pumping volatile liquid. (Only with Cat. 2 pumps)
