Runpacet color oil pump is a specialized pumping device used in industries such as plastics, coatings, and inks for precise delivery of liquid color pastes, color oils, or additives. It features accurate metering, corrosion resistance, and easy cleaning, making it compatible with automated production lines to enhance the stability and efficiency of coloring processes.
**Precision Metering & Delivery:**
Utilizes a precision pump structure to ensure consistent dosing of liquid colorants, maintaining stable coloring ratios (typical error ≤ ±0.01%).
**Anti-Solidification & Anti-Settling:**
Some models come equipped with stirring functions to prevent color paste solidification or pigment settling during idle periods.
**Multi-Media Compatibility:**
Suitable for high-viscosity color pastes (e.g., liquid color oils for plastics), low-viscosity solvent-based colorants, and functional additives (e.g., flame retardants, UV stabilizers).
**Pump Types**
**Gear Pump:**
Features: Positive displacement pump with stable output flow, ideal for medium-to-high viscosity media (e.g., colorants with 1000-50000 mPa·s viscosity).
**Materials:**
Stainless steel (304/316L) or ceramic for corrosion resistance and contamination prevention.
**Screw Pump:**
Features: Low shear force, making it suitable for shear-sensitive media (e.g., colorants containing nano-pigments), with a wide flow range (0.1-100L/min).
