The P1-R & P2-R Pneumatic Rotary Valve Pump is a specialized fluid dispensing solution designed for accurate, consistent distribution of medium-high viscosity liquids, gels, and particle-containing fluids. Engineered by ZEEPACK, this pump series combines 316 stainless steel construction (for durability and corrosion resistance) with advanced features like micrometer volume adjustment and built-in speed control to deliver exceptional dispensing accuracy (±0.5%)—critical for industries where precision is non-negotiable. With models covering dispensing volumes from 0-0.23mL (P1-R03) to 0-20.1mL (P2-R20), it adapts to diverse applications, from small-batch cosmetic filling to high-volume industrial use. Its optimized air consumption (12.5-23.5 L/min) and compact design enable easy integration into existing production lines, reducing operational costs and boosting efficiency—making it ideal for battery manufacturing, cosmetics, food, and medical sectors.
The pump excels at dispensing medium-high viscosity liquids (e.g., Vaseline, grease, silicone oil, butter) without clogging or inconsistent flow. This addresses a critical gap in standard pumps, which struggle with thick or viscous fluids.
Equipped with micrometer volume adjustment, the pump achieves a typical dispensing accuracy (±0.5%). This ensures every dose meets exact specifications, essential for applications like battery zinc-gel filling and pharmaceutical fluid dispensing.
Built-in speed control regulates plunger movement, maintaining consistency across varying operating conditions. This prevents over-dispensing or under-dispensing, reducing material waste and ensuring product uniformity.
The entire pump body uses 316 stainless steel construction, offering corrosion resistance and compliance with food-grade (FDA) and pharmaceutical (GMP) standards. This material extends the pump’s lifespan, even in harsh industrial environments.
With air consumption of 12.5 L/min (P1-R series) and 23.5 L/min (P2-R series), the pump is energy-efficient. This reduces compressed air costs, a significant advantage for long-term production operations.
Across models, the pump covers dispensing volumes from 0-0.23mL to 0-20.1mL. This versatility allows it to handle small-dose applications (e.g., mascara) and larger-volume needs (e.g., sauce filling).
Unlike many pumps, it safely dispenses fluids with particles—such as herb-infused dressings or industrial greases with additives. This expands its utility across food and industrial sectors.
The pump’s compact dimensions (e.g., P1-R03: 45×80×247mm; P2-R20: 50×90×293.3mm) enable seamless integration into automated lines. It requires minimal space, suitable for both small workshops and large factories.
