- Commodity name: CF3500G Intelligent Distribution Gear Pump
F flow range: 1,428–15,000 mL/min; ideal for high-precision liquid transfer and filling; brushless DC motor drive, offering high accuracy and maintenance-free operation; pump head made of 316L stainless steel, with PEEK gears providing excellent corrosion resistance; magnetic drive to effectively prevent overload‑induced damage; fully sealed design ensuring zero leakage; transfer or filling accuracy up to ±0.5%; maximum outlet pressure of 10 kgf—higher pressure results in reduced flow rate; four operating modes: flow‑rate mode, timed constant‑speed mode, constant‑speed quantitative mode, and timed quantitative mode; industrial touchscreen and membrane keypad for simultaneous operation, simple, convenient, and fast; cumulative volume counting, scheduled filling, and the ability to store multiple programs for easy recall; multiple external control interfaces, including 0–5 V, 0–10 V, 4–20 mA, 0–10 kHz, RS‑485, and external signal start/stop control.
Product Introduction
Flow range: 1428–15,000 mL/min; 
Suitable for high-precision liquid transfer and filling; 
Brushless DC motor drive, high precision, maintenance-free; 
316L‑material pump head, PEEK gear material, with excellent corrosion resistance; 
Magnetic drive, effectively preventing overload-related damage to the machine; 
Fully sealed design, leak-free; 
The transmission or filling accuracy can reach ±0.5%. 
Outlet pressure: 10 kgf; as pressure increases, flow rate decreases. 
Four operating modes: flow‑rate mode, timed constant‑speed mode, constant‑speed quantitative mode, and timed quantitative mode. 
The industrial touch screen and membrane keypad operate in tandem, offering simplicity, convenience, and speed. 
Cumulative liquid volume, scheduled filling, and the ability to pre-store multiple formulations for easy retrieval; 
It supports multiple external control modes, including 0–5 V, 0–10 V, 4–20 mA, 0–10 kHz, RS‑485, and external signal‑based start/stop control, among others. Control Panel
Industrial touch screen combined with membrane keypad operation
Four operating modes: flow‑rate mode, timed constant‑speed mode, constant‑speed quantitative mode, and timed quantitative mode. 
Four physical buttons—Mode, Full Speed, Direction, and Start/Stop—make operation even more convenient.
