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, 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.
