The Masterflex L/S digital pump drive from Cole-Parmer (Vernon Hills, IL) has a high-contrast LCD graphical interface that eases setup and operation. The LCD shows four operating modes: continuous run, timed dispense, copy dispense, and volume dispense, allowing you to view pump performance continually. The menu-driven interface lets you select one of seven languages for programming and operation.
The pump’s brushless motor offers ±0.1% speed control accuracy with a 6000:1 turndown ratio for a wider flow range. Enhanced dispensing features include volume dispense, timed dispense, and copy/repeat. A programmable dispense interval allows hands-free dispensing and filling. Cumulative volume feature totalizes volume dispensed over multiple cycles. Available models include bidirectional RS-232 or USB connectivity for control through a PC, and an IP66- rated all-stainless steel housing for use in sanitary, washdown applications.
