1.2.3 Accuracy
1.2.4 Admission Pressure and Counterpressure / Suction Height
Maximum admission pressure at the suction side [bar]
Minimum counterpressure at the pressure valve of the pump [bar]
Note
A positive pressure difference of 2 bar min. is required between the suction valve
and the pressure valve in order for the dosing pump to operate correctly. If the total
counterpressure (at the dosing point) and geodetic height difference between the
suction valve and the dosing point is less than 2 bar (20 m WS), a pressure
retention valve must be installed directly in front of the dosing point.
Maximum counterpressure* [bar]
*Observe the maximum permissible temperatures
Maximum suction height * [m] for media with a viscosity similar to water
*applies to a filled dosing head
Maximum suction height [m] for media with maximum permissible viscosity
1.2.5 Sound Pressure Level
1.2.6 Degree of Protection
Depending on the motor variant that is selected, see type plate of the motor.
The specified degree of protection can only be ensured, if the mains cable is connected
with the same degree of protection.
