Product Overview
The magnet drive principle of the MPB150 micro magnetic drive gear pump provides a completely sealed pump chamber. No pulsation, no leakage, low noise, high performance, compact size, long lifespan. Designed to meet working conditions around 10-15 L/min flow rate and 0.5-8 bar differential pressure.

Key Features

• No pulse accurate delivery
  Through the gears to provide continuous accurate fluid transportation; with servo and stepper motor delivery accuracy of +/-0.5%.
• Strong vacuum suction capacity
  High and stable conveyance pressure. High pressure delivery in low viscosity liquids.
• No leakage
  Magnetic drive and static O-ring seal isolate the pumped medium from the outside to achieve leak-free operation.
• Low Noise
  Torque transmitted through magnetic coupling, avoiding mechanical contact; helical gears are designed for smooth meshing to reduce friction, impact and vibration.
• Long Lifespan
  High-performance precision technology and advanced craftsmanship extend operational lifespan.

Materials & Applications
Gears: PEEK. Housing and gear shaft: premium 316L stainless steel (alternative options: 304, PPS). Sealing material: static O-ring FKM or PTFE (FKM: stronger wear resistance and higher temperature performance; PTFE: stronger acid/alkali and corrosion resistance). Power transmission via internal/external magnetic coupling for leak-free conveyance. Applicable media examples: deionized water, methanol, urea solution, kerosene, additives, lubricating oil, lye, ammonia solution, cobalt solution, dialysate, ethylene glycol, freon, ink, glycerin, phenolic resin, curing agent, fragrance essence, fluorinated liquids and other fluids requiring precise, contamination-free pumping.
