Grundfos DDA Dosing Pump - 7.5-16 FCM-PV/T/CF-31U2U2IG - 97722862

Features

• DDA 7.5-16


• FCM-PV/T/C-F-31U2U2


• The SMART Digital DDA is a compact positive displacement, diaphragm
  dosing pump with variable-speed drive (stepper motor) and intelligent
  control electronics with minimum energy consumption.


• The SMART Digital Dosing series operates at full stroke length to
  ensure optimum accuracy, priming and suction, even for high-viscosity
  or degassing liquids.


• The duration of each discharge stroke varies according to the capacity
  set, resulting in optimum smooth and continuous discharge flow.


• The click-stop mounting plate allows installation in three different
  positions without using any additional accessories.


• The control cube can be turned easily into front, left or right
  position.


• The click wheel and the multi-coloured backlit graphical, plain-text
  LC display make commissioning and operation intuitive.


• The control elements are protected by a transparent cover.


• The sensor-based FlowControl (FC) system detects malfunctions directly
  in the dosing head and displays them in plain text in the alarm menu,
  e.g. air bubbles, line burst, overpressure.


• The integrated flow measurement function (only FCM) measures the
  actual flow and makes additional monitoring and control equipment
  redundant (accuracy of ± 1,5 % of set value in case of trouble-free
  process).


• The measured flow is displayed and can be integrated in the process
  control, e.g. SCADA.


• Furthermore, the AutoFlowAdapt function (only FCM) automatically
  adjusts the pump speed according to the process conditions to maintain
  target flow even at e.g. varying backpressure or air bubbles foaming
  (degassing drive strategy).


• The dosing head is composed of:


• Long lifetime and universal, chemically resistant full-PTFE diaphragm.


• Double ball valves for highest dosing accuracy.


• Deaeration valve for easy start-up. •Pressure sensor.


• Operation modes:


• Manual dosing in ml/h, I/h or gph.


• Pulse control in ml/pulse (incl. memory function).


• Analog control 0/4-20 mA (scalable).


• Pulse-based batch function in ml, l or gal.


• Timer-based batch function (Dosing timer, cycle or week).


• Fieldbus control (Genibus prepared for ProfibusDP E-box).


• Other features:


• Auto deaeration during pump standby to avoid breakdowns due to
  air-locking.


• Two SlowMode steps (anti-cavitation), 50 % (maximum flow: 3.75 l/h)
  and 25 % (maximum flow: 1.88 l/h), e.g. for high-viscosity or
  degassing liquids.


• Service information display to show when service and which wear-part
  order number is required.


• Two-step key lock function to protect the pump against unauthorised
  access.


• Additional display function to provide further information, e.g. the
  actual mA input signal.


• Counter for total dosed volume (resettable), operating hours, etc.


• Save and load customised settings as well as reload of factory
  settings.


• Signal inputs/outputs:


• Input for pulse, analog 0/4-20mA, external stop.


• Input for low-level and empty-tank signal.


• Two potential-free output relays for max. 30 V AC/DC (configurable,
  e.g. alarm, stroke signal, pump dosing, timer etc.)


• Output analog 0/4-20mA.


• Fieldbus communication interface (GeniBus, also for additional
  Profibus DP E-box to retrofit).

Applications

• Dosing pumps are used in a variety of applications from agriculture,
  industry, manufacturing to medicine
