These digital pump drives offer a high-contrast graphical LCD showing four operating modes (continuous run, timed dispense, copy dispense, and volume dispense), allowing users to view pump performance continually. The menu-driven interface features a choice of seven languages for programming and operation. The maintenance-free, brushless motor offers ±0.1% speed control accuracy with a 6,000:1 turndown ratio for wider flow range. Enhanced dispensing features of the drive include volume dispense, timed dispense, and copy/repeat. A programmable dispense interval allows hands-free dispensing and filling. These durable digital pump drives are compatible with all existing L/S pump heads.
