Masterflex Modular Digital Dispensing Pump Drive 77301-21 and 77301-22 Benchtop Controller

Masterflex Modular Digital Dispensing Pump Drive 77301-21 and 77301-22 Benchtop Controller

L/S Variable-Speed Brushless Digital Dispensing Drive

Equipped with 77200-60 Pump Head

The Digital PWM BLDC Drive controls the speed of MASTERFLEX® L/S® Pump Heads to provide flow rates from 0.10 to 3400 mL/min.

Mount up to 2 (600 rpm) or 4 (100 rpm) MASTERFLEX® L/S® Pump Heads and all MASTERFLEX-compatible pump
heads.

Maintenance-free brushless motor. Special features for precise repetitive dispensing. Precise PWM speed control. Quiet operation. Tachometer feedback for ±0.25% speed control. Stackable. Pump heads can be stacked. Calibration capability. Programmable for all L/S® tubing sizes

Flow rate: 0.6 to 3400 mL/min; cartridge flow rate: 0.006 to 1700 mL/min. Flow rate depends on drive rpm and tubing size.
Four-digit LED display shows four different parameters: – Flow rate: 0.1 or 1 mL; autoranging – Dispense volume: 1 mL to 999 L (in 1 mL increments) – Copy: 1 to 99 repetitions, 20 µL to 999 L each – Motor rpm: 10 to 600 rpm; 1 rpm resolution
Dispense by: mL—volume in mL of each dispense, 0.001 to 9999 mL; copy—1 to 9,999 dispense cycles; or SEC—time between each dispense: 1 to 9,999 secs.
Programmable dispense interval lets you set delay time between dispense cycles for automatic, repetitive dispensing
Reversible 1⁄10-hp motor. Pump in either direction; purge before or after pumping.
Designed for accurate dispensing and low maintenance, these drives feature precise PWM speed control (±0.3%) and an efficient, maintenance-free brushless motor. The modular digital drives with wall-mount controller (B) give you an IP56-rated controller with full remote control features.
Programmed calibration ensures dispense and display accuracy—drive stores one calibration value per tubing size. Program the drive via the simple membrane keypad; keypad lock/unlock feature protects settings. For standard applications select tubing size and desired flow rate—drive automatically locks in required rpm

Benchtop controller is tough ABS plastic—IP22-rated for easy wipe-down l 25-ft (7.6-m) cable connects motor and controller— place where convenient.
