    The SMART Digital DDA is a compact diaphragm metering pump with speed-controlled stepper motor drive and intelligent control electronics. Thanks to the stepper motor, SmartDigital dosing pumps always work with the full stroke length for optimum dosing accuracy. The stepper motor drive enables low-pulsation and continuous dosing, even at low dosing volume flows. The flexible mounting plate allows wall and floor mounting without additional mounting accessories. The operating cube can be rotated into three different positions (left/front/right). The dosing pump is operated via a rotary/push wheel. The Smart Digital dosing pump has an LCD display with plain text display and 4-colour status backlighting (white/green/yellow/red). The operating display is protected from environmental influences by a hinged protective cover.
