Helical gear pump MPB003

for chemicalsmagnetic-drivestationary

Overview
The magnetic drive principle of the MPB003 micro magnetic gear pump provides a completely sealed pump chamber. No pulsation, no leakage, low noise, compact size and long operational life. Designed to operate in the flow range 5–300 ml/min and differential pressures from 0.5 to 20 bar.

Key Features

• No pulsation, accurate delivery: helical gears provide continuous, precise fluid transport; with servo and stepper motor control achievable accuracy ±0.5%.
• Strong suction and stable conveyance pressure — suitable for high-pressure delivery of low-viscosity liquids.
• Leak-free design: magnetic drive and static O-ring seal isolate the fluid from the external environment.
• Low noise operation: torque transmitted via magnetic coupling avoids mechanical contact; helical gear meshing reduces friction, impact and vibration.
• Extended service life: precision manufacturing and materials selected for long-term operation.

Materials and Construction
MPB003 series micro magnetic gear pumps: gears made of high-performance engineering plastic PEEK; housing and shaft options: 304 or 316L stainless steel; sealing options: static O-ring FKM or PTFE. Power transmission via internal/external magnetic coupling ensures leak-free conveyance. Suitable for precise flow control, high-purity and contamination-sensitive liquid handling such as micro-transfer, dosing, lubrication, spraying, dispensing, sampling, coding, boosting, circulation, coating, painting and metering.
