This equipment is used for precision micro-dosing of various liquids in high-end industries including pharmaceuticals, lithium battery electrolyte, acids, solvents, dairy products, adhesives and chemical reagents.

Key Features

Designed for precision micro-dispensing, filling and liquid injection of high-purity tiny-volume fluids
Valve-free structure delivers ultra-stable flow with flow accuracy within ±3%
Pump core features high wear resistance, acid & alkali corrosion resistance and high temperature tolerance for long service life
All wetted parts made of ceramic to avoid chemical reactions with media
Positive displacement plunger design with reciprocating rotary operation; flow rate adjustable via stroke length and rotation cycle
Zero waste, bubble-free, leak-free, no dripping and anti-clogging performance
Versatile system with multiple volume & speed options; reversible liquid transfer available on demand
Automatic stop once the preset liquid volume is reached
Configurable functions: forward suction, back suction, back suction volume, delayed dosing, standby cleaning and output counting
