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 sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head and displays them in plain text in the alarm menu. FCM measures the actual pressure and flow rate and eliminates the need for additional monitoring and control devices (accuracy of ± 1.5 % of the set value in a trouble-free process). The measured pressure and flow are displayed and can be integrated into the process control system, e.g. SCADA. In addition, the AutoFlowAdapt function automatically adjusts the pump speed to the process conditions to maintain the target flow even with fluctuating back pressure or air bubble formation (degassing drive strategy). 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,
  • A pressure sensor.

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:

  • The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head.
  • Measurement of actual pressure and flow.
  • AutoFlowAdapt automatically adjusts the pump speed to the process conditions (what you set is what you get).
  • 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.
  • ConditionCheck analyses the pump and the system where the pump is installed.
  • 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.

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 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).

Contemporary translation of a set of Christian classics
Format: Hardcover
How did the New Testament come to be formed? What books were left out? What did some of those books say? These are some of the questions on the minds of many curious people today. Too often, local congregations ignore these questions, to the detriment of the church. But these questions about Christian origins are very, very real in the hearts and minds of many people today. Now, from one of the most significant writers about Christian origins today comes a completely new edition of the Apostolic Fathers -- the letters of Clement, the letters of Ignatius, the letter of Polycarp, the Martyrdom of Polycarp, the Didache, the Epistle of Barnabas, the fragments of Papias and Quadratus, the Epistle to Diognetus, and the Shepherd of Hermas. These were early Christian writings that are generally attributed to church leaders of the late first and early second centuries CE (and, in most cases, are probably authentic). Clement, for example, was an early leader in Rome (circa 96 CE); Ignatius wrote a number of letters to churches in various cities (circa 110 CE), sort of following in the footsteps of Paul. This two-volume set replaces the classic edition of the Apostolic Fathers in the Loeb Classical Library edited by Kirsopp Lake nearly a century ago. As with all books in the Loeb Classical Library, the original (in this case, Greek) text is presented on the left-hand pages, and an English translation is presented on the right. The text is extremely readable, and the introductions to each of the books are clear, succinct, and to the point. Some of these books almost made it into the New Testament! The epistles of Clement are found in some early New Testament manuscripts and were widely read in the early churches. The Shepherd of Hermas may have been the most widely read book by early Christians. Several of these books were probably written before some of books in the New Testament. In an age in which people are asking questions about the origins of Christianity and the authority of the scriptures, it is crucial that we have at least a basic understanding of our early history. In my mind, a decent familiarity with the Apostolic Fathers -- as well as the Dead Sea Scrolls and the Nag Hammadi library -- is essential. This two-volume set is extremely valuable. Ehrman's critical textual work, his contemporary translations, and his up-to-date introductions are a welcome addition to current literature. The trained scholar will delight in having a new critical edition of the Greek text . . . but an ordinary lay reader could also profit tremendously from reading some of these early Christian writings that were not deemed to be sufficiently close to the first generation of apostles to make the cut into the New Testament.
