Overview

The Hicera V series pumps are high precision micro dosing pumps designed for injecting extremely small liquid volumes with high accuracy. The V-03 model offers repeatability of ±0.5%, making it suitable for applications requiring precise liquid dosing.

Key Features

• High Precision Micro Dosing: Capable of injecting micron-level liquid volumes with excellent repeatability.
• Adjustable Discharge Volume: Discharge volume can be controlled by changing the pump head angle.
• Valve-less Structure: Eliminates air lock issues, allowing injection of liquids containing air bubbles without interruption.
• Stable Discharge Capacity: Maintains consistent output despite pressure fluctuations on suction or discharge sides.
• Compact and Lightweight Design: The valve-less structure enables flexible installation orientations, including vertical and horizontal.
• Low Pulsation Duplex Model: Available to provide low pulsation injection without the need for additional air chambers or accumulators.

Operating Principle

The pump operates with a plunger that reciprocates while rotating. The rotating plunger alternately opens and closes the suction and discharge ports, enabling liquid intake and discharge. This mechanism ensures precise dosing and smooth flow.

Low Pulsation Mechanism

The duplex model employs a patented high transmission efficiency driving mechanism that combines the discharge volumes of two pump heads. This design significantly reduces pulsation, improving flow stability.

Model Variants

• V-03: Standard high precision micro dosing pump with stepping motor.
• V-05 and V-10: Ultra-precision dispensers with enhanced wear resistance and stability.
• V-15 Duplex Model: Low pulsation model with two pump heads for smoother discharge.

Performance and Reliability

The pumps are designed for ultra-high precision and stable operation over time. The valve-less design prevents air lock and ensures consistent discharge even with liquids containing air bubbles. The compact size and lightweight construction facilitate easy integration into various systems.

Installation and Usage Recommendations

• Thanks to the valve-less structure, the pump can be installed in any orientation (vertical or horizontal).
• The duplex model is recommended where low pulsation dosing is critical, eliminating the need for external pulsation dampeners.
• Adjust discharge volume by modifying the pump head angle to meet specific dosing requirements.

Critical Parameters and Limitations

• Repeatability is ±0.5% for the V-03 model with stepping motor.
• Discharge volume adjustment depends on mechanical angle settings of the pump head.
• Valve-less design is optimized for liquids that may contain air bubbles but may require consideration for highly viscous or particulate-laden fluids.

Summary

The Hicera V series pumps provide a compact, precise, and reliable solution for micro dosing applications. Their valve-less design and duplex low pulsation options make them versatile for various industrial and laboratory uses where accurate liquid injection is essential.
