New YW series submerged sewage pump features long-life operation, easy to use and reliable safety with no maintenance as following description:

First: Corrupt-resistant, Dirt-resistant and Block-resistant

1. In order to operate in high efficiency without any block, series optimized flowcomponents as pump case or impeller etc. can be selected according to released medium Therefore it assures the outstanding hydraulic performance and work life of submerged sewage pump when it pumps abrasive medium with suspending granule, long fiber and corrosive
2. With smoothly spacious flow channel and wonderful structure of filter mesh insuck cylinder, it is suitable for pumping both fiber with length of 5 times than pump nozzle and solid granule with diameter of 50 percent of pump nozzle. When the granule is larger than the limit, the pump can still operate safely.
3. The motor is not submersible without any submerged cable. It can pump and transport waste water of temperature at 65 C or lower. Moreover it meets the requirement ofhigher temperature of dirt-resistant, corrosion-resistant and oil-resistant application situation as maximum as possible.

Second: Easy to use, Safty and Long-Life Operation

1. The impeller is immersed in the liquid, so there are no any problems of exhausting It also starts conveniently.
2. It can be equipped with automatic control panel of liquid level by customer As a result, it starts and stops by liquid level control, it is no need to do the work manually
3. Solid maintenance-free design, strong and good rigidity of main shaft with famousbearing, as well as previously infused high-temperature-resistant lubrication grease, all make pump operate steadily in lower noise. Bearing and main shaft are completely isolated by shaft seal system without contacting feeded medium, which assures the scheduled work life of shaft
4. It adopts double mechanical seals with frictional accessories of corrupt-resistantcemented tungsten carbide or silicon carbide, as well as special hydraulic dynamical seal. It makes the shaft seal no leakage in continuously 8000-hour operation.

Third: Steady, Reliable and Deep Level

1. The system is vertical structure, pump case and impeller can be set in the depth of0.5~10 meters under liquid surface. The motor can be set above liquid surface. Throughconnection of transmission assemblies , which are designed and manufactured with modularization method (including bracket, coupling, transmission shaft, transmission pipe.intermediate bracket, intermediate bearing and end bearing), it can directly drive no-block single or double flow channel impeller to operate steadily without vibration.
2. There is one suction barrel with filter mesh at the inlet, the position and shape offilter mesh make liquid level as deep as possible. Moreover it enjoys excellent performance of block-resistant
3. The integrated construction features strong, stable and long-life design.
4. It is possible to operate with common Y series motor. As selecting Y2 series motoror outside motor, it needn’t build any special pump house so that construction investment can be  It is easy to assemble, operate and replace on the ground.
5. With comprehensive improvement in hydraulic mould, mechanical structure, technicalprocess, material choose and motor etc, it makes sure that the submerged sewage pump operates in long reliability with the performance of granule-resistant, corrupt-resistant and attrite-resistant
