Masterflex® I/P® Digital Process Drives

Flow rate 0.0006 to 26 LPM with I/P tubing—flow rate depends on drive rpm, pump head, number of pump heads, and tubing size
Digital interface with graphical LCD shows pump performance and operating mode— continuous run, timed dispense, copy dispense, or volume dispense
Remote control available using analog communication—voltage, current and contact closure
Select your preferred language from the user-friendly menu for programming and operation
Dispense by Volume in mL (0.001 to 9,999 mL), L, or gal; Copy—1 to 9,999 dispense cycles; or Time—time interval of on/off cycles (1 sec to 99 hr, 59 min, 59 sec per cycle)
Antidrip function ensures dispensing accuracy
Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio
Rugged housing is NEMA 4X (IP66) rated for washdown
Choose models with open head sensor technology for enhanced user safety
Advanced network and communication models feature either Ethernet/IP or Profibus communication
