The SMART Digital DDA-C 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. Depending on the set capacity, the duration of the discharge stroke varies, ensuring an optimal, uniform 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 easily turned to the front, left or right position. The click wheel and the multi-coloured backlit graphic plain-text LC display enable intuitive commissioning and operation. The control elements are protected by a transparent cover. The DDA-C has built-in connectivity that allows easy setup and tracking via the Grundfos GO app as well as easy integration into a Modbus RTU or TCP bus system. The dosing head includes the following parts:

  • A durable and chemically resistant full PTFE diaphragm,
  • Double ball valves for maximum dosing accuracy,
  • A deaeration valve for easy start-up.

Operation modes and functions:

  • 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 (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).
  • Cloud control and monitoring (Smart Digital Chempairing Suite; Grundfos Connect).

Other features:

  • Auto deaeration during pump standby to avoid stand-still due to air-locking.
  • Two SlowMode steps (anti-cavitation), 50 % and 25 % maximum flow, e.g. for high-viscosity or degassing liquids.
  • Max. Capacity to limit the capacity of the pump to a set maximum.
  • Service information display to show when service and which wear-part order numbers are required.
  • Two-step key lock function to protect the pump against unauthorised access.
  • Multi-parameter dashboard function to provide further information on up to 4 parameters.
  • Counter for total dosed volume (resettable), operating hours, etc.
  • Save, copy and load customised settings as well as reload factory settings.

  • 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 (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).

From Babylon to Timbuktu
Format: Paperback
What I like about this book is how it truly I must say base all it information on facts and allows the reader to search for themselves that truth. Very informative reading! There are many books such as this, which goes along with what the authour here is stating. A well written and well research issue, I have yet to come across. This book invites anyone, no matter of race or ethnicity, to see the real, yet truth behind ones identity as respects where He/She came from when it comes to the lineage of Noah's three sons: Ham, Shem, Japheth. It breaks it down using Biblical though logic to determine who, when, where, how, the races came about. A Must Read!!! Let truth be told... who the true sons of Noah (Ham, Shem, Japheth) when it relates to my culture (as a Negro or Hebrew Israelite). What's interesting about this book is how it goes into by way of explaining, through a series of logics base on facts, showing you the differention between the two Sons of Noah: Ham and Shem (who were actually of non-colour), according to their identity. The Bible is clear on this fact, however, the "myth" that Ham was "curse" as a race which lead to their skin colour turning Black, which lead to the mass genocide and reason for slavery. It is rather interesting how many miss the two of Noah's Sons: Ham & Shem being of non-colour and that Yeshua (Jesus) was actually from the line of Shem, therefore, being a person of non-colour... According to the actual fact presented, HAM in the Bible had four (4) sons: Cush (Ethiopia), Mizraim (Egyptians), Phut (Libya -N.Africans), Canaan (S.Africa). These were the progenitour of the Dark Races, NOT the Negroes!(Genesis 10:6) The Negroes were from Shem, who were the Hebrew Israelites! However, the progenitours of Japheth was the Greek, Romans, Europeans or the Caucasians. According to Alexander Hamilton Bible Dictionary pg. 330, defines HAM: "The youngest son of Noah born probably about 96 years, before the flood. One of the 8 person to live during the flood. He became the progenitor of the dark races, Not the Negroes, but the Egyptians, Ethiopians, Libyans, and Canaanites." A MUST READ!!!
