GW pipeline type high efficiency non-clogging sewage pump

product description
GW pipeline high-efficiency non-clogging sewage pump is a vertical single-suction single-stage centrifugal drainage pump. Any position in the pipeline. The pump and the motor are directly connected to the same axis, which is an electromechanical integrated product, with a compact structure and stable performance. The large flow passage anti-blocking hydraulic component design is used to greatly improve the ability of dirt to pass through. It can effectively pass 5 times the fiber diameter of the pump and solid particles with a diameter of about 50% of the pump diameter. Reasonable design, reasonable supporting motor, high efficiency, and significant energy saving effect. The mechanical seal adopts hard wear-resistant tungsten carbide, which is durable and wear-resistant, which can make the pump run continuously for more than 8000 hours. Advanced hydraulic performance, high machine efficiency and low running noise. A protective cover is added to the wind blade end of the motor, and the whole machine can be placed outdoors to work without a machine room, which can save a lot of infrastructure costs. Use within the range of the lift to ensure that the motor is not overloaded.

Structure description
GW series non-blocking single-stage pipeline sewage pumps have the same inlet and outlet on the same level and have the same specifications. The vertical structure has a small footprint, the motor and the pump are coaxial, and the installation chassis is provided for easy and stable installation. The impeller uses a single ( Double) runner with good passing performance.

Application scope of pipeline type non-clogging sewage pump
GW series pipeline non-clogging sewage pump is suitable for the discharge of severely polluted wastewater from factories, sewage drainage stations in main residential areas, water distribution systems of urban sewage treatment plants, drainage systems of civil air defense systems, water supply equipment of water plants, hospitals, hotels Sewage discharge, municipal engineering construction sites, mining auxiliary equipment, rural biogas ponds, farmland irrigation, and other industries. Contaminated sewage and dirt from conveyor belts can also be used in clean water and with weakly corrosive media.

Operating conditions of pipeline type non-clogging sewage pump
A. The usage temperature of pipeline sewage pump is ≤40 ℃, humidity is ≤95%; altitude is ≤1000m.
B. The medium temperature does not exceed 60 ° C, and the medium weight is 1 ~ 1.3kg / dm3.
C, the range of use of cast iron material is PH5 ~ 9.
D, stainless steel can use general corrosive media.
E. The altitude of the use environment does not exceed 1000 meters. When the above conditions are exceeded, it should be put forward when ordering in order to provide you with more reliable products.
Note: If the user has special temperature and medium requirements, please specify the details of the conveying medium when ordering, so that the unit can provide more reliable products.

Product features of pipeline type non-clogging sewage pump
1. The pump and the motor are directly connected to the same axis, which is an electromechanical integration product, with a compact structure and stable performance.
2. The large flow channel anti-blocking hydraulic component design greatly improves the ability of dirt to pass through. It can effectively pass the fiber material 5 times the diameter of the pump and solid particles with a diameter of about 50% of the pump diameter.
3. Reasonable design, reasonable supporting motor, high efficiency, low noise, and significant energy saving effect.
4. The mechanical seal adopts hard wear-resistant tungsten carbide, which is durable and wear-resistant, which can make the pump run continuously for more than 8000 hours.
5. The pump has a vertical structure, the center line of the inlet and outlet is on the same level, and the specifications of the inlet and outlet flanges are the same. Installation and removal are very convenient.
6, small footprint, no need to build a machine room, can save a lot of infrastructure costs; add a protective cover to the motor blade end, the whole machine can be placed outdoors.
