Cutting submersible sewage pump with cutting technology. Product features of sewage pump:
1. The cutting submersible sewage pump with cutting technology is an electric pump that is not afraid of blockage, has significant energy saving, reliable operation, and easy maintenance. It effectively solves the problems of PN slurry pump not being able to pump heavy particles and PW and PWA sewage pumps being prone to blockage.
2. The cutting submersible sewage pump with cutting technology also adopts domestic mechanical seals, with a sealing life of over 3000 hours. The pump shaft and fastening screws are all made of high-strength materials, with good corrosion resistance. During operation, it is equipped with a motor leakage protector to protect against leakage, short circuit, and phase failure, without the need for special supervision. It is an ideal equipment for various industries to extract particles, impurities, short fibers, and slag slurry.
The submersible sewage pump with cutting technology has a particularly strong ability to discharge sewage, with good cutting performance. It can chop up impurities such as long fibers, plastics, paper, belts, cloth strips, straw, ropes, etc. in the sewage and discharge them. Using the * method, it is designed with reasonable hydraulic characteristics, so that the electric pump can operate at full head. The excellent combination of dry motor and water pump makes the total efficiency of the electric pump reach the same level as the ASS belt cutting device series products of West German ABS company. The electric pump adopts high-quality hard alloy, double end mechanical seal and skeleton oil seal assembly surface, which should not exceed 1/2 of the height of the motor, and the temperature of the pumped waste should not exceed 40 ℃.
The cutting submersible sewage pump with cutting technology is mainly used to discharge domestic wastewater, sewage, human feces and urine, as well as solid suspended solids and non corrosive media containing short fiber paper scraps, sawdust, starch, sediment, ore particles, etc. The temperature of the pumped liquid does not exceed 40 ℃, the density is not more than 1200kg/m3, and the pH value is about 9. This electric pump adopts a double end mechanical seal and a rotating impeller. The impeller is made of stainless steel, wear-resistant, non clogging, non winding, and has the advantages of small volume, compact structure, and easy portability.
The cutting submersible sewage pump with cutting technology is mainly used for engineering sewage and domestic sewage.
For example: (1) Used for construction sites, engineering foundation construction, municipal facilities, and water treatment plants.
(2) Sewage discharge from the basement of various high-rise buildings, civil air defense pits, subways, and other underground structures.
(3) Sewage treatment and circulating water transportation for small and medium-sized enterprises.
(4) The pumping of slag and slurry from factories and mining enterprises such as food, paper, brewing, steel and non-ferrous metals, leather, textile, pharmaceutical, cement plants, etc.
(5) Chicken farms, pig farms, various animal husbandry industries, fish ponds are used for pumping and cleaning ponds, oxygenation, septic tanks, and other occasions for the transportation of human and animal manure and urine.
