The motor is controlled by a frequency converter and protected by Pt100 sensors

Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking

after-run function

DDA 30-4 AR-PVC/V/C-F-31I002FG The SMART Digital DDA is a compact positive displacement

for high-viscosity or degassing liquids

pressure valve 99229033 The motor is controlled byPressure valves provide a constant counterpressure and prevent siphoning Opening pressure is fix at 3 bar. They are particularly required for DDA FC or DDA FCM pumps at very small flow rates. Pressure valves are installed either directly on the pump discharge side, or on the pressure relief valve. Spring material is Alloy C 4 (NiMo16CrTi, material number 2. 4610).
