Overview of MT-HTP High Temperature Magnetic Pump

MT-HTP type high-temperature magnetic drive centrifugal pump (referred to as high-temperature magnetic pump). The main feature of a high-temperature magnetic pump is that when the outer magnetic steel of the magnetic actuator rotates, the magnetic field lines pass through the gap and isolation sleeve and act on the inner magnetic steel, causing the pump shaft to rotate synchronously with the motor and transmitting torque without contact. At the power input end of the pump shaft, due to the liquid being enclosed in a stationary isolation sleeve without a dynamic seal, the inevitable phenomena of running, emitting, dripping, and leaking in the petrochemical industry are eliminated, and there is no leakage at all. This type of magnetic pump is suitable for transporting toxic, harmful, flammable, explosive, and valuable liquid media, and is an ideal pump for creating leak free, pollution-free civilized workshops and factories.

Precautions for using MT-HTP high-temperature magnetic pump

1. Due to the fact that the cooling and lubrication of magnetic pump bearings rely on the medium being transported, it is absolutely forbidden to operate them in idle mode, while also avoiding the possibility of spatiotemporal rotation caused by power outages and restarts during operation.

2. If the conveyed medium contains solid particles, a filter screen should be added to the pump inlet; if it contains ferromagnetic particles, a magnetic filter should be added.

3. The ambient temperature of the pump during use should be less than 40 ℃, and the temperature rise of the motor should not exceed 75 ℃.

4. The conveyed medium and its temperature should be within the allowable range of the pump material (see attached table for details). The operating temperature of engineering plastic pumps is less than 60 ℃, the operating temperature of metal pumps is less than 100 ℃, the conveying suction pressure is not more than 0.2mpa, the high working pressure is 1.6mpa, the density is not more than 1600kg/m3, and the particle size is not more than 30 × 10-6m2/s, which is a liquid without hard particles and fibers.

5. For media that are prone to precipitation and crystallization during transportation, they should be cleaned promptly after use to drain the accumulated liquid in the pump.

6. After running the pump for 1500 hours, the wear of the bearings and end face moving rings should be disassembled and inspected, and vulnerable parts that are no longer suitable for use should be replaced.

7. The magnetic couplings inside and outside the pump are made of high-performance permanent magnet materials, which may pose potential hazards to the following components. Please keep the following components at a distance from this series of pumps. Such as pacemakers, credit cards and other magnetic cards, calculators, computer disks, watches, etc.
