Gear pump MPB030

for chemicalsmagnetic-drivestationary

Short description
MPB030 magnetic drive gear pump driven by an AC servo motor delivers precise, continuous fluid transfer at 1.5–3 L/min (max 3 L/min) and resists outlet pressures from 0.5 to 15 bar. Designed for accurate dosing and stable operation in applications requiring closed-loop speed and position control.

Features

• No pulse accurate delivery
  Helical gears provide continuous, pulse-free transport; with the AC servo motor the delivery accuracy reaches ±0.2%.
• Strong suction and high-pressure capability
  High and stable conveyance pressure enables reliable intake and high-pressure delivery even for low-viscosity fluids.
• No leakage
  Magnetic coupling and static O-ring sealing isolate the pumped medium from the environment to prevent leaks.
• Low noise and energy-efficient
  Magnetic torque transmission eliminates mechanical contact; helical gear meshing reduces vibration and friction; motor output is adjusted to load for energy savings.
• Long service life
  High-performance materials and brushless motor options remove carbon brushes to extend operational lifetime.

Additional description
The MPB030 uses an AC brushless servo motor with magnetic coupling (REPM outer ring magnetic circuit) and operates with an independent controller for precise, stable control and long life. External driver control of motor speed and direction enables fine adjustment of current, speed and position. Closed-loop feedback provides fast dynamic response, high torque density and accurate position control, suitable for high-speed operation with frequent starts and stops.
