Product Overview
The magnet-drive MPB1000 micro magnetic gear pump provides a fully sealed pump chamber with no pulsation, no leakage and low noise. Compact and high-performance, it is designed for precise metering and continuous transfer. Typical operating range: flows up to 100 L/min (model-dependent) and differential pressures from 0.5 to 5 bar for larger models.

Key Features

• No-pulse accurate delivery
  Helical gears provide continuous, pulse-free fluid transport. With servo or stepper motor control, delivery accuracy can reach ±0.5%.
• Strong suction capability
  Stable conveyance and good suction performance allow reliable delivery of low-viscosity liquids at higher pressure.
• Leak-free operation
  Magnetic coupling with static O-ring sealing (FKM or PTFE) isolates the pumped medium to eliminate external leakage.
• Low noise
  Torque transmission via magnetic coupling avoids mechanical contact; helical gear design reduces friction, impact and vibration.
• Long service life
  High-performance engineering materials and precision manufacturing extend operational lifetime.

Description
The MPB1000 is part of the MPB series of micro magnetic gear pumps. Standard gear material is PEEK; housing and shafts are available in 316L stainless steel and other options. Power is transmitted via internal/external magnetic coupling to ensure leak-free operation. The pump suits applications requiring precise flow control, high purity and non-contamination in chemical dosing, lubrication, cooling and laboratory systems.

Compatible media (examples)
Deionized water, methanol, urea solution, kerosene, additives, lubricating oil, caustic solutions, ammonia solution, cobalt solution, dialysate, ethylene glycol, freon, ink, glycerin, phenolic resin, curing agent, fragrance oils, fluorinated liquids.
