[Three rain valve to recommend the star product - Mechanical seal] Description: sewage pump is a pump and motor Siamese WQ15-12-1.1 pumps and sump pumps sneaked while working with the general horizontal pumps or vertical sewage pump compared sewage pump compact structure, small footprint. Easy installation and maintenance, a large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance very easy. Continuous operation for a long time. Due to pump sewage pump and motor coaxial WQ15-30-3 pumps, short axis, rotating parts and light weight, it is relatively small bearing on the loads (radial), life is much longer than the average pump. There is no cavitation damage and irrigation water and other issues. Especially after a little to the operator has brought great convenience. Vibration noise, motor temperature low environmental pollution. [Three rain valve to recommend the star product - Mechanical seal]: 1, if the choice of stainless steel sewage pump, but also to find out the pH of the water quality and diameter containing particles, select the appropriate stainless steel. 304 for general between PH4 ~ 10, over this range is recommended to use 316 or 316L stainless steel. 2, the pump must be within the rated head range, to ensure that the motor is not overloaded. Such as pumps, lift is actually needed 30 meters, but less than 30 meters of water pump with a standard lift pumping, this case belongs to the wrong use, will cause the pump motor overload WQ27-15-2.2, in severe cases, motor will be burned. 3, the pump must dredge pipe, if the pipe barrier will also cause motor overload, severe cases may burn out the motor. WQ27-15-2.2 pumps | Jinnan pumps | pumps selected three rain GB provided by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd.
