WQ / QW Submersible Sewage Pump Product Description: sewage pump for pump and motor coaxial one, driven by the motor shaft while working pump impeller rotation, will transfer energy to the slurry medium, to produce a certain velocity, driving solid flow, achieve slurry transport. WQ / QW Submersible Sewage Pump Features: 1. High quality bearings with high rotation, low noise, low vibration, low wear torque characteristics, and prolong life. 2. volute impeller flow channel, the kinds of impeller blades are no impeller, impeller is one from the inlet to the outlet of a curved flow channel, especially suitable for pumping large particles and long fibers of the media, anti-blocking properties Well, the power curve is relatively stable, easy to produce super-power issues. 3. The use of dual-channel tandem mechanical seals, mechanical seal faces: alloy carbide mechanical seal rubber parts: nitrile rubber, mechanical seals spring: stainless steel; durable, wear-resistant. 4. copper electrical motor with GB 5. leak cable, even if it will not cause the motor to the water damaged seals 6. sturdy wooden packaging, plastic bags wrapped body, shockproof foam bottom. 7. Automatic coupling device and automatic pump control cabinet available for purchase. The main purpose WQ / QW Submersible Sewage Pump: ① enterprises wastewater discharge. ② urban sewage treatment plant discharge system. ③ subway, basement, air defense systems drainage stations. ④ hospitals, hotels, high-rise building sewage discharges. ⑤ residential sewage pumping station. ⑥ municipal engineering, construction sites in the diluted slurry emissions. ⑦ waterworks water supply installations. ⑧ sewage farms and rural irrigation. ⑨ water treatment equipment for mining and exploration. ⑩ people instead labors bear, river mud suction. WQ / QW submersible sewage pump sewage conditions: 1. medium temperature does not exceed 50 ℃, density 1.0-1.3kg / m, PH value in the range of 6-9?. 2. No internal gravity circulation cooling system pumps, motors partially exposed surface does not exceed 1/2. 3. Under normal circumstances, the use of lift pump must be within range, but to ensure that the motor carrier for the use in the whole head, should further specify when ordering. 4. During operation, the motor current must not exceed the rated motor current.
