The Plunger Pump Precision Liquid Injection Equipment is a high-accuracy fluid dispensing system designed for controlled, repeatable liquid delivery in industrial, medical, and laboratory applications. Utilizing a plunger pump mechanism, it ensures ultra-precise volumetric dosing (µL to mL range) with minimal pulsation, making it ideal for applications such as adhesives, lubricants, pharmaceuticals, and microfluidic systems.
Features
- The parts in contact with the medium are all made of ceramics.
- Suitable for high-end and micro-precision dosing, filling, addition, injection, spraying, and marking of liquid media. Featuring a valveless design, it ensures extremely stable flow with a flow accuracy of ±0.3%.
- The pump core and pump sleeve are manufactured with a combination of nanotechnology and gel casting molding technology, resulting in a uniform microstructure and extremely high density. The components are precisely matched, utilizing advanced ceramic technology that achieves self-sealing and self-lubricating properties without the need for additional seals or lubricants.
- The pump sleeve and its components are resistant to acids, alkalis, and can adapt to liquid metering in harsh environments.
- The design features a positive displacement piston structure with reciprocating rotational operation. The flow rate can be adjusted by modifying the stroke length or rotational cycle.
- The liquid injection is no waste, no bubbles, no leakage, no dribbling, and no clogging.
- The system has high-performance features. It offers multiple capacity and speed options, and can instantly reverse the liquid transfer direction.
- Without dynamic sealing parts and vulnerable parts, it is easy to maintain.
- Capable of metering and injecting liquid according to preset parameters. It automatically stops metering when the specified liquid volume is reached.
- Equipped with a standard communication interface, it can be used independently or conveniently communicate with PLC or industrial control computers.
- Operators can calculate the total liquid volume based on actual production needs using the formula: Q_total (Total Liquid Volume) = Q_stroke (Stroke Volume) * N_stroke (Number of Strokes).
- Features configurable functional modes such as forward pumping, reverse pumping, reverse pumping volume, delayed metering, standby cleaning, and production counting.
- The machine is compact and aesthetically designed, flexible to use, easy to operate, stable in performance, and safe and reliable.
