Helical gear pump MPB015

for chemicalsmagnetic-drivevacuum-assisted priming

Overview
The MPB015 micro magnetic drive gear pump uses magnetic coupling to create a fully sealed pumping chamber, delivering leak-free operation with negligible pulsation. It offers low noise, compact dimensions and a long service life. Designed for precise pumping across a working flow range of approximately 20–2000 ml/min and differential pressures up to 20 bar.

Key Features

• No pulse, accurate delivery
  Helical gears ensure continuous, smooth fluid transport. With servo or stepper motor drive, delivery accuracy can reach ±0.5%.
• Strong suction and pressure capability
  Stable conveyance at high and low viscosities; suitable for pressure delivery in low-viscosity fluids.
• Leak-free operation
  Magnetic drive with static O‑ring sealing isolates the pumped medium from the environment to prevent leaks.
• Low noise
  Torque is transmitted via magnetic coupling without mechanical contact; helical gear meshing reduces friction, impact and vibration.
• Extended service life
  High-precision components and quality manufacturing increase operational lifespan.

Product description
The MPB015 series are micro magnetic gear pumps combining PEEK gears with optional 316L stainless steel or PPS housings and shafts in 316L or ceramic. Power is transmitted through internal/external magnetic couplings to ensure a sealed, leak-free transfer. The pump is optimized for precise flow control, high purity and non-contaminating transfer in laboratory, chemical dosing, micro-transfer and dispensing systems.
