Key features

Compact positive displacement pump
Digital display with intelligent control electronics
Variable-speed drive

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 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

Operation modes:

Manual dosing in mL/h, L/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: 60 L/h) and 25 % (maximum flow
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)

ADDITIONAL FEATURES

Versatile operation modes

Minimum energy consumption

APPLICATIONS

Chemical dosing in water treatment related applications

Range of industrial applications including metering of chemical products
