Manufacturers supply WQF (F on behalf of corrosion) corrosion-resistant submersible sewage pump WQF (F on behalf of corrosion) corrosion-resistant submersible sewage pumps are widely used to transport civil engineering, mining industry, agriculture, forestry, fisheries and other operations contain dirt, small solid particles sewage, is a small mobile device to send the sewage discharge. It features easy to use, efficient, clean and easy maintenance. One, WQF type corrosion sewage submersible pumps Product Overview 1, sewage submersible pump uses a unique single, double channel impeller structure, greatly improving the dirt capacity, and can effectively through five times caliber pump fiber material with a diameter of about 50% of the pump diameter of solid particles. 2, the mechanical seal with double mechanical seal or double type, and make long runs in the oil chamber, material used anticorrosive hard tungsten carbide materials, can pump more than 8000 hours of continuous operation safety. 3, the overall structure of the pump is compact, small size, low noise, energy-saving effect is remarkable, easy maintenance, no need to build pumping stations, dive into the water to work, greatly reducing the project cost. 4, pump equipped with overheating or over-current protection device to prevent motor overload fever, leakage protection device can be set according to user requirements. For more pump power 7.5kw and has high accuracy, interference seal leakage monitoring device (according to user needs to configure). 5, according to user needs, with automatic security control cabinet, the pump leakage, leakage, overload and overtemperature monitoring to ensure the safety and reliability of pump operation. 6, the float switch may change according to the level required for automatic control of pump start and stop, no special care, extremely easy to use. 7. The need to be equipped for dual-rail automatic coupling installation system to facilitate the installation of the pump, which can meet different occasions. 8. Installation fixed automatic coupling installation and installation freedom of movement, which can meet different occasions. Two, WQF corrosion-resistant submersible sewage pump main purpose for construction of buildings, hospitals, residential areas, municipal engineering, traffic and construction, sewage plants, small-scale sewage treatment and other occasions, the carriage containing solid particles, long fiber waste, rainwater and sewage. Three, WQF type corrosion conditions a sewage submersible pumps, medium temperature does not exceed 60 ℃, medium weight less than 1.2kg / dm3, pumping medium particle content greater than 60% by weight, pumping medium PH value of 4-10. 2, no internal gravity circulation cooling system pumps, motors partially exposed surface shall not exceed 1/2 of the motor. 3, the main parts of the pump is made of cast iron, it can not be used for pumping corrosive media, For pumping corrosive media, please describe the use of the conditions and requirements for special orders, we will have targeted for your design and service.
