1) Arcuate bevel gears are used instead of worm gears, thereby economizing on energy with high efficiency,and saving over 20% electric energy over traditional models.
2) The arcuate-bevel gear is made of chromium-manganese-titanium with carbon-nitride surface treatment. Ensuring long usage life spans and high rigidty.
3) Mechanical seal is available to prevent oil leakage.Have good water current circulation as the making of large aera water wave.
4) Inside protectors are avaible to avoid the motor being accidentally burnt out.
