for chemicalsfor food productsmagnetic-drive

Short description
MPB1000 is a micro magnetic-drive gear pump driven by an AC brushless servo motor. Displacement 33 ml/rev, flow up to 100 L/min, typical outlet pressure range 0.5–5 bar. Designed for high-speed, accurate control, stable operation and applications requiring leak-free fluid isolation.

Key features

• No-pulse accurate delivery
  Helical gear pair provides continuous, pulse-free fluid transfer. With servo control, delivery accuracy reaches ±0.2%.
• Strong suction and stable pressure
  Capable of effective suction under vacuum and stable discharge for low-viscosity liquids at high throughput.
• No external leakage
  Magnetic drive with static O-ring sealing isolates pumped medium from atmosphere to prevent leaks.
• Low noise and energy efficient
  Magnetic coupling transmits torque without mechanical contact. Helical gears reduce friction and vibration; motor output is adjusted to load to save energy.
• Long service life
  High-performance materials and brushless motor design remove carbon brushes, extending maintenance intervals.

Pump description
The MPB1000 uses an AC brushless servo motor coupled via an outer-ring magnetic circuit (magnetic coupling). An external controller enables closed-loop control of speed, torque and position for precise dosing and dynamic response, suitable for frequent starts/stops and high-speed operation.
