Differences between magnetic pumps, pneumatic diaphragm pumps and metering pumps and applications
Magnetic pump structure without the traditional direct rigid spindle drive, the motor power output and pump blades or gears for power transmission; but through the permanent magnet disk, the role of magnetic attraction, the torque transmission in the past, the middle of anti-corrosion The partition. Suitable for pumping corrosive liquids, large flow, high head. Pneumatic diaphragm pump structure is a bit like the traditional automotive gas-driven brake drive section, with the volume change of the rubber film to be equipped with one-way valve, suitable for conveying medium with particles, such as slurry, pump pressure, flow, simple structure ,low cost. The metering pump represented by gear pump, high pressure, high flow rate, high cost, the relationship between the corner and the flow rate is determined and stable.
