Gear pump MPB150

for crude oilfor hydrocarbonsfuel oil

Product Overview
MPB150 magnetic drive gear pump is driven by an AC explosion‑proof asynchronous motor. It delivers 10–15 L/min with an outlet pressure range of 0.5–8 bar and a nominal displacement of 5.4 ml/rev. The unit is designed for leak‑free transfer of flammable liquids and for frequent start/stop operation.

Key Descriptions
The MPB150 miniature magnetic drive gear pump uses an AC asynchronous explosion‑proof motor. The motor shaft links to the external magnetic circuit (REPM) to drive the internal gears. Operation characteristics include steady speed, high torque, stable running and long service life. The explosion‑proof AC motor is intended for use in petroleum, oilfield, fuel oil and other flammable liquid transfer applications.

Features

• No pulsation: gear transmission provides continuous, accurate fluid delivery.
• Strong suction capability: maintains stable delivery pressure and supports high‑pressure transfer of low‑viscosity liquids.
• No leakage: magnetic coupling and static O‑ring seal isolate the medium inside the pump.
• Convenient operation: three‑phase asynchronous motors enable quick starts and suit frequent switching scenarios.
• High energy efficiency: three‑phase asynchronous motors reduce energy consumption and operating costs.
