[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. For example, the actual lift is required 30 meters, but less than 30 meters of water pump with a standard lift pumping, this case belongs to the wrong usage will cause motor overload, the pump motor will be burned in severe cases. 3, the pump must dredge pipe, if the pipe barrier will also cause motor overload, severe cases may burn out the motor. [Three rain valve to recommend the star product - Mechanical seal] Description: Product Overview: 1. With the crowd channel anti-clogging design of hydraulic components, greatly improving the dirt capacity, and can effectively through the pump five times the diameter of the fiber material and the diameter of the pump diameter of about 50% of the solid particles. 2. Design a reasonable WQ10-18-1.5 pumps, supporting reasonable motor, high efficiency, energy saving effect is remarkable. 3. The mechanical seal is double tandem seal, made of hard wear-resistant tungsten carbide, a durable, wear characteristics, can pump more than 800 hours continuous operation safety. 4. Pump compact structure, small size, easy to move, easy to install, no need to build pumping stations, dive into the water to work, greatly reducing the project cost. 5. The interior features a water pump oil pump probe WQ50-6-1.5, when the water pump mechanical seal damage, WQ25-7-1.5 pump water into the oil chamber, the probe signal occurs, the pump implementation of conservation. 6. According to user needs with automatic security control cabinet, the pump leakage, leakage, overload and overtemperature monitoring to ensure safe and reliable operation of the pump. WQ20-15-1.5 pumps, Dingxi pumps, sewage pump manufacturers choose three rain provided by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) (www.tjsymf.com) strong, credible, in Tianjin seal industry has accumulated a large number of loyal customers.
