GNWQ sewage cutting sewage pump Model meaning
65GNWQ25-15-2.2 Clog-free mobile cutting pump for household septic tank farming is a cutting type sewage sewage pump, which is designed to transport sewage and dirt. Its cutting part has a unique spiral structure and a sharp blade design. The material is made of material with a Rockwell hardness of 48HR or above (special materials need to be customized in advance) . On the premise of ensuring high water conservancy performance and exceeding similar products, it also has a certain cutting ability to ensure the superior cutting function of straw, cotton, cloth, baby diapers and other wastes after being chopped and discharged. GNWQ series sewage cutting pump is suitable for 0-25 meters, large flow, medium and low lift, full lift and low energy consumption. This product also adopts a removable cutterhead design. Different types of cutterheads can be replaced according to different usage environments, including municipal type and special type for livestock farms.
65GNWQ25-15-2.2 Clog-free mobile cutting pump for household septic tank farming working conditions:
1. The medium temperature does not exceed 60ºC, the maximum medium temperature in continuous use does not exceed 50ºC, the medium density is 1.0-1.3×1000kg/m3, and the PH value is in the range of 5-9;
2. When the water pump is working, the motor part should not be exposed more than 1/2 of the water;
3. The main parts of this type of pump are made of cast iron, so it cannot be used to pump highly corrosive liquids;
Note: If users have special requirements, they can put them forward when ordering in order to provide more reliable products.
The submersible reamer pump adopts the design of large-channel anti-clogging hydraulic components and can effectively pass solid particles with a diameter of 50-125mm. The water pump components are well designed, and a cutting rotary cutter head is installed in front of the impeller so that impurities in the pumped medium are crushed before entering the impeller flow channel without clogging.The automatic coupling system is easy to install and does not need to build a pump room, which can reduce a lot of engineering costs and operating costs.
Precautions for use of submersible sewage pump with cutting knife
(1) Before using the electric pump, you must first check whether the cable is damaged. When transporting and installing the water pump, cut the iron to pull or damage the cable to avoid accidents caused by water leakage after the cable ruptures. If the cable is hard to crack, the cable should be replaced immediately. And use a megohmmeter to check whether the insulation resistance of the electric pump is normal (the insulation resistance must not be less than 1 megohm)
(2) Recognize the grounding wire (the grounding wire is usually yellow or green or connected with a grounding mark), and connect the grounding wire according to the prescribed procedures. (Our factory's ground wire is equipped with a ground mark).
(3) Choose a suitable protector (such as leakage protector, air switch, phase failure overcurrent protector, etc.) and do not connect directly with a knife switch.
(4) Connect the power cord according to the standard, test the power supply, check whether the electric pump is operating normally, and determine whether the steering is correct. If the steering is incorrect, just swap any two of the three power cords (pay attention to the operation) The time cannot exceed half a minute).
(5) Install the water outlet joint and water outlet hose (or iron pipe), tie a rope on the handle of the electric pump (cables must not be used to replace the hanging rope), put the electric pump into the liquid book to be pumped, and turn on the power supply and is ready to use.
(6) In order to ensure personal safety, when the electric pump is connected to power, it is strictly prohibited to install and launch water operations near the electric pump (such as moving or inspecting, troubleshooting, etc.) and touching the electric pump to prevent accidents caused by electric pump leakage!
(7) It is strictly prohibited for the entire electric pump to be exposed to the water for long-term operation (or short-term operation). The "start" and "stop" of the electric pump should not be too frequent to prevent overheating and damage to the motor.
(8) Long-term pumping of liquids with high sand content will cause greater wear and tear on the flow-passing parts of the GNWQ sewage pump with cutting device. It is recommended to use our cyclonic sewage submersible electric pump product.
(9) If it is found that the GNWQ sewage pump with cutting device does not rotate, the protector trips, the fuse blows, etc. when it is running, the power supply should be cut off immediately and check whether there are any problems with the power protector wiring, etc.
If these external devices are normal, the electric pump may be faulty and should not be used at this time to avoid an accident!

Principles for selecting sewage pumps - DFIN Pump Industry
1. High mechanical reliability, low noise, and minimal vibration.
2. Economically, it is necessary to comprehensively consider the total cost of equipment, operation, maintenance, and management fees to minimize them.
3. Make the selected pump type and performance meet the requirements of process parameters such as device flow rate, head, pressure, temperature, cavitation flow rate, and suction stroke.
4. Must meet the requirements of medium characteristics.
For pumps that transport flammable, explosive, toxic, or valuable media, reliable shaft seals or leak free pumps are required, such as magnetic drive pumps, diaphragm pumps, and shielded pumps
For pumps transporting corrosive media, it is required that the convection components use corrosion-resistant materials, such as AFB stainless steel corrosion-resistant pumps and CQF engineering plastic magnetic drive pumps.
For pumps transporting media containing solid particles, it is required that the convection components be made of wear-resistant materials, and if necessary, the shaft seal should be flushed with clean liquid.
