Pumps are devices commonly used in industry and households. Their integral element is the engine that drives the working tool, generating the necessary pressure difference between the suction and discharge sides. This makes it possible to pump liquids or transport them to a higher level. There are many types of pumps available on the market, some of which are the most commonly used Submersible pumps for sewage, sludge and dewatering. Sewage pumping devices are usually equipped with a cutting mechanism and are so-called grinder pumps.
What are grinder pumps used for?
The basic function of grinder pumps, as the name suggests, is to grind sewage and sludge in order to increase the efficiency of their transport and pumping. Pumps with grinder are widely used in the water and sewage sector for pumping sewage with fibrous impurities. They are worth using in the case of small diameter pressure pipes and when sewage is transported over long distances. The condition for installing a pump with a grinder is a large distance from the main sewer line. Pumps with a grinder are suitable if the transport distance is greater than 300 meters, the pumping height exceeds 12 meters vertically, and the discharge pipeline is less than 40 millimeters. Pumps with grinder are also used when large differences in ground levels preclude the use of other solutions.
Pumps with a grinder are very often used in places that need to be adapted into sanitary rooms, but are located outside the designated sewage line. The same applies to kitchen islands equipped with a sink. Pump-shredders they are also widely used in catering establishments, and their basic function in such cases is to protect the sewage system against clogging with food remains. They are also successfully used in beauty and hairdressing salons and public toilets. They are used in the food, paper and agricultural industries as well as in hospitals, hotels and camping sites.
What is worth knowing about grinder pumps?
The basic structural element of the grinder pump is the grinding mechanism, consisting of a knife and a cutting disc. Both parts should be made of tool steel with increased abrasion resistance. The shredding mechanism is installed in front of the rotor. The waste is crushed in a hermetic pump tank. The knives cut solid impurities from the sewage, and then the pump pumps them into the sewage system, septic tank or home sewage treatment plant. Pumps with a grinder enable effective adaptation to the terrain, which is particularly important in locations with complex terrain. The type of pump inlet is adapted to the type of sanitary device being serviced - it will be different in the case of a washbasin, and different in the case of a bidet or washing machine.
The pump casing must be resistant to mechanical damage and corrosion. Grinder pumps can be used to pump out not only sewage, but also sludge and slurry. When choosing the appropriate pump with a grinder, pay attention to the additional equipment with a thermal fuse. Pump-shredders they are also equipped with convenient on and off buttons and an electronic control system. They are installed on a flat surface, approximately 5 centimeters from the wall, or integrated with the toilet bowl. Grinders are an increasingly used solution in channel pumps.
