Gear pump MPB100

for chemicalsmagnetic-drivestationary

Product Overview
MPB100 micro magnetic-drive gear pump driven by a 380W brushless DC motor. Designed for continuous, low-pulsation fluid transfer with a nominal displacement of 3.6 ml/rev and flow rates up to 10 LPM. Suitable for a wide viscosity range and industrial process control applications.

Key Features

• No-pulse accurate delivery
  Positive gear displacement provides continuous, repeatable volumetric delivery with delivery accuracy comparable to servo/stepper control (±0.5%).
• High suction and pressure capability
  Stable delivery performance with effective suction; capable of handling low-viscosity fluids at elevated discharge pressures.
• Leak-free containment
  Magnetic drive with static O-ring sealing isolates the pumped medium from the atmosphere to prevent leakage.
• Low noise and smooth operation
  Magnetic coupling avoids mechanical contact; helical gears ensure smooth meshing to reduce friction, impact and vibration.
• Extended service life
  High-performance materials and brushless motor design eliminate carbon brushes and reduce maintenance.

Product Details
The MPB100 uses a brushless DC motor paired with a dedicated controller for stable operation and precise regulation. Speed and direction are controlled via an external drive, enabling current control, speed control, position control and other precision control modes for process integration.
