Magnetic force transmission is adopted for the pump gearing between motor and pump that is first time in our country.

Characteristic:
● Magnetic force transmission transfer moment, the dynamic seal of the main shaft that transfer twist moment is calm seal (no framework oil seal and mechanical seal), it is achieved that there is no leak when the dynamical is being transferred.
● No machine contacting and Rubbing noise, avoid the high frequency vibration when dynamical is being transferred, stable operation.
● Possess overload self-protective function.
● No impact when start compare to Rigid coupling, Install \ dismantle to unload, test and maintain expediently.
● Sheath for insulation and Calm seal replaced moving seal. Vacuum and lubricant leak is avoided completely because of abrasion of the shaft moving seal.
● Do not need lubricate, no medium and lubricant pollutions, Purify the environment
The Sealing performance is foreign to the shaft speed.
Installation dimension and performance of the series pump is the same with the general roots pump.
