GF Series Peristaltic Pumps with Intelligent Flow Rate Control
Intelligent Peristaltic Pumps with Flow Control, Calibration, and Closed-Loop Control
Description
The GF Series combines the advantages of a high-performance peristaltic pump with precise flow rate control. Unlike conventional speed-controlled pumps, the GF Series allows users to directly specify a desired flow rate or a defined dispensing volume. This makes it ideal for precise dosing, laboratory, and automation applications.
- Precise flow rate control from 0.15 µL/min to 3,250 mL/min
- Direct input of flow rate and dispensing volume
- Three color-coded operating modes for intuitive operation
- Automatic flow rate and volume calibration
- Optional closed-loop operation with an external flow meter
- Up to 65,000:1 control ratio and ±0.1% speed accuracy
- Touchscreen operation with 3.5-inch color display
- RS485 interface with Modbus RTU and Longer OEM protocol
- Analog and digital control via 0-5 V, 0-10 V, 4-20 mA, and 0-10 kHz
- Flow rates up to 3,250 mL/min in a compact design
- Three-level user management and keypad lock for secure operation
Precise Dispensing Instead of Simple Speed Control
The GF Series expands the functionality of the GS Series with direct flow rate and volume control. In addition to continuous pumping and timed dispensing, it offers a dedicated volume mode for accurately dispensing predefined liquid volumes. When used with an optional flow meter, the GF Series also supports automatic calibration and closed-loop control for maximum dispensing accuracy.
Precise Dispensing with Three Operating Modes
The GF Series features an intuitive 3.5-inch color touchscreen. Different operating modes are immediately recognizable through distinct color schemes, improving usability and reducing operator errors.
Continuous Pumping Mode (Blue)
In Continuous Mode, a constant flow rate or pump speed is maintained. The blue user interface clearly indicates continuous operation at a glance.
Timed Dispensing Mode (Violet)
For recurring dispensing processes, run time, interval time, and the number of cycles can be freely defined. The purple interface makes it easy to distinguish this mode from continuous pumping operation.
Volume Dispensing Mode (Orange)
In Single Volume Mode, a precisely defined target volume is dispensed. The orange interface clearly identifies this high-precision operating mode.
Closed-Loop Control for Maximum Accuracy
A key feature of the GF Series is the ability to connect an optional flow meter. This allows the pump to monitor the actual flow rate and automatically adjust its operation as needed. Variations caused by tubing wear, back pressure, or changes in the fluid system are automatically compensated for, ensuring consistently accurate dosing performance.
Extensive Control and Communication Features
The pumps support a wide range of integration options:
- RS485 interface
- Modbus RTU
- Longer OEM protocol
- 0-5 V, 0-10 V, 4-20 mA control signals
- 0-10 kHz frequency input
- Start/stop and direction control
- Multiple active control sources can be used simultaneously
