Sewage pump is a pump and motor connected, and at the same time into the liquid work pump products, compared with the general horizontal pump or vertical sewage pump, sewage pump compact structure, small footprint. Easy installation and maintenance, large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance is quite convenient. Long continuous operation time. Sewage pump because pump and motor coaxial, shaft is short, rotating parts light weight, so the bearing load (radial) is relatively small, life is much longer than the general pump. There is no cavitation damage and irrigation water problems. In particular, the latter point brings great convenience to the operator. Low vibration noise, low motor temperature rise, no pollution to the environment.
