Product Characteristics

Dust-proof and splash-proof: protection class. IP54, a fully enclosed strueture, higher quality, and available for outdoor use.
The motor’s maximum working temperature is 20℃ higher than that of the common Y motors: Y2 motor and class F insulation, and the high-quality single-stage pump can still be used reliably at rated power even at 120℃.
The shaft seal’s service life is more than double longer: thanks to its new mechanical seal and forced circulation circulatory system, its operating environment is improved with zero leakage plus a life more than double longer than that of common mechanical seal of ordinary domestic water pumps.
More energy-saving: the Y2 motor is 2-4% more efficient; with a special structure, the impeller has an excellent hydraulic model, leading to smooth flowing and small losses, thus ensuring the pump’s optimal performance.
Quieter: the motor is directly connected and coaxial with the pump,leading to small vibration and low noise; the motor fin shape has a reasonable layout to reduce noise, while the high-quality bearings contribute to stable and quiet operation; and the large-diameter impeller, after strict dynamic balancing, contributes to less vibration.
Easier to use: thanks to its modular design and strong versatility of parts,it’s easy for dis-assembly; and the pump’s inlet and outlet have the same diameter while its body is supported by feet, thus resulting in stable and reliable operation.
Greatly space effective: with a unique mounting structure, it’s greatly space-effective and saves more than 40% of construction investment; and a low-power pump can be mounted on any position of the pipeline like a valve without any base plate, so it will not occupy any area of the pump room.
Less management costs: the entire shaft plus bearings with special structures and configuration, high-quality casting, with high dimensional precision and a nice look, a strong overload capacity of the Y2 motor and other characteristics can reduce the maintenance costs significantly, extend the pump’s life greatly and save management expenses by 50%-70%.
