Helical gear pump MPB075

waterfor chemicalsfor ink

Overview
The MPB075 is a magnetic drive micro gear pump delivering 1.70 ml per revolution with nominal flow capacity around 6 L/min. The magnetic coupling and static O-ring sealing create a fully sealed pump chamber to provide leak-free, low-pulsation fluid transfer for industrial dosing and circulation applications.

Key Features

• No-pulsation accurate delivery
  Helical gear design ensures continuous, precise volumetric displacement; with servo or stepper motor control delivery accuracy can reach ±0.5%.
• Strong suction and pressure capability
  Stable conveyance performance enabling high-pressure delivery of low-viscosity liquids.
• Leak-free operation
  Magnetic transmission combined with static O-ring isolation prevents medium leakage to the external environment.
• Low noise transmission
  Torque is transmitted magnetically without mechanical contact; helical gears reduce friction and vibration.
• Extended service life
  Precision manufacturing and material selection support prolonged operational life under specified conditions.

Materials & Construction
Gears: PEEK high-performance engineering plastic. Housing and gear shaft: standard 316L stainless steel (304 and PPS options available). Seals: static O-ring in FKM or PTFE. Power transmission: internal/external magnetic coupling for sealed, leak-free drive.

Typical Applications
Designed for precise flow control and contamination-sensitive fluids. Suitable media include deionized water, methanol, urea solution, kerosene, additives, lubricants, alkaline solutions, ammonia solution, cobalt solution, dialysate, ethylene glycol, refrigerants, inks, glycerin, phenolic resins, curing agents, fragrances, fluorinated liquids and similar media.

Technical Parameters (partial table — MPB series)
Model / Displacement (ml/rev) / Flow (L/min) / Viscosity Range (cP) / Temperature Range / Pressure Diff. / Inlet Filter / Inlet Vacuum / Noise
MPB075 / 1.7 ml/rev / 6.0 L/min / 0–3000 cP / -40°C ~ 100°C (material review required for high temperature) / 0–20 bar / recommended 400 mesh / down to -0.85 bar / 4000 RPM < 60 dB

Additional Technical Notes
Product family ranges from MPB003 (0.1 ml/rev, ~0.3 L/min) up to MPB1000 (33 ml/rev, ~100 L/min); viscosity and pressure capability vary by model — consult MPB series technical table for selection. Smaller MPB models (MPB003–MPB075) are typically rated up to 3000 cP; larger models may reach up to 12000 cP depending on configuration.
