Micropump Cavity Pump with DC Motor Speed Controller

Micropump Cavity Pump with DC Motor Speed Controller

General Description

The Micropump Cavity Pump with DC Motor Speed Controller is a precision-engineered external gear pump designed for smooth, pulse-free fluid transfer. Featuring advanced cavity-style gear technology paired with digital motor speed control, the system ensures consistent, accurate fluid delivery across a wide range of pressures, viscosities, and flow conditions.

At HiTechTrader, we offer the Micropump Cavity Pump with DC Motor Speed Controller, a precision-engineered gear pump system designed for smooth, pulse-free fluid transfer in laboratory and industrial environments. Featuring cavity-style external gear technology, the pump delivers high volumetric efficiency and consistent performance across a broad range of viscosities, pressures, and flow conditions. Paired with a digitally controlled DC motor, it provides precise, continuous adjustment of flow rates with smooth start/stop operation that extends pump life and reduces mechanical stress. Constructed from stainless steel, PEEK, and other corrosion-resistant materials, the Micropump system offers wide chemical compatibility, compact integration, and reliable long-term operation. Ideal for chemical dosing, pharmaceutical liquid transfer, food and beverage metering, and analytical instrumentation, this versatile pump ensures accurate, reproducible results for demanding applications.

Pump Technology and Design

1. Utilizes cavity-style external gears: fluid is transported in discrete cavities formed between gear teeth.
2. Near-zero slip design minimizes backflow, enhancing volumetric efficiency.
3. Capable of handling higher pressures and viscous fluids with reduced wear compared to conventional gear pumps.
4. Compact construction with available magnetic drive options for leak-free performance.

Motor and Speed Control

1. Driven by a DC motor with an integrated speed controller.
2. Enables fine, continuous adjustment of flow rates via speed variation.
3. Provides smooth acceleration and deceleration, avoiding surges or fluid hammering.
4. Compatible with automation systems for advanced process integration.
5. Improves energy efficiency by matching pump output to process demand.
6. Controlled start/stop sequences extend pump life by reducing mechanical stress.
