When purchasing a shielded pump, it is necessary to consider whether the motor is explosion-proof, what the explosion-proof classification is, and what the level of waterproofing and dust protection is
Thread Content
When purchasing a shielded pump, are there any requirements regarding whether the motor is explosion-proof, the explosion protection rating, the level of water and dust resistance, as well as the insulation grade?
It depends on the operating environment; if it is an explosion-proof, water-resistant, or dust-proof area, the requirements of that environment must be met.
Isn’t every shielded pump explosion-proof, as well as waterproof and dustproof? Because it only has static seals, which can achieve zero leakage
Home use booster pumps are also shielded pumps; they are not explosion-proof
Yes, just like a normal motor – make the same requests as you would for one
The minimum DLLBT4 for shielded pumps is usually also H-class insulation
In shielded pumps, although the motor rotor is immersed in the sealed material, the stator coils and terminal connections remain in contact with the atmosphere; therefore, explosion protection is necessary.
Depending on the different operating conditions, corresponding requirements are specified; these requirements generally need to be indicated
