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