DDA is one of the GRUNDFOS injection pumps that is operated by a stepper motor. This model is produced in different series, producing a flow rate of 7.5 to 400 liters per hour and a pressure of 4 to 16 bars. The valve head and hub material of this series are produced in both steel and PVC, which are suitable for transferring corrosive fluids with PFTE diaphragms.
The ( GRUNDFOS ) DDA series metering pump in maximum mode (when the Stork volume is at 100%) transfers fluid with a maximum flow rate of 7.5 liters per hour and with a viscosity of 50 millipascals. In minimum mode (when the stroke volume is 25%), it transfers fluid with a flow rate of 1.88 liters per hour and with a viscosity of 2500 millipascals. Among the capabilities of this device the following can be mentioned:
- You mentioned 4 to 20 mA output to control the device using the inverter.
- It has a pressure relief screw and automatic ventilation.
- anti-cavitation
- digital screen
- Password locking system
- Showing parts that are worn and need to be repaired and replaced.
- Timer and alarm
