Gear pump MPB150

for chemicalsmagnetic-driveself-priming

Product overview
MPB150 magnetic-drive gear pump driven by a brushless DC (BLDC) motor. Designed for continuous pulse-free delivery up to 10 L/min with a maximum outlet pressure of 10 bar. Suitable for precise transfer and dosing where leak-free operation, low noise and wide viscosity range handling are required, commonly used in cooling systems and new energy applications.

Key features

• Pulse-free accurate delivery
  Helical gears provide continuous, accurate fluid displacement with delivery accuracy comparable to servo/stepper systems (±0.5%).
• Strong suction and stable pressure
  Capable of high vacuum suction and stable high-pressure delivery, including low-viscosity liquids.
• Leak-free magnetic drive
  Magnetic coupling with a static O-ring seal isolates the pumped medium, preventing external leakage.
• Low noise operation
  Torque transmission via magnetic coupling and helical gear meshing reduces mechanical contact, friction, impact and vibration.
• Long service life
  High-performance materials and brushless motor design eliminate carbon brushes and extend operational lifetime.
