What is the difference between a sewage pump and a clean water pump? Why can't sewage be pumped with clean water?
The main difference between water pump and sewage pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
The clean water pump and the sewage pump are different from the design. It also requires different material. Sewage pump requires material of solid phase friction, acid and alkali corrosion resistance, and other high resistance, and clean water pump can ignore these requirements. In addition, the sewage pump in a large proportion of large solids content of the fluid can also work normally, and clean water pump in the design can not meet the long-term use of this environment requirements.Of course, clean water pump can also be used for sewage, but only temporary measures, and the life expectancy, the effect can not be guaranteed.
In short, the main difference between clean water pump and sewage pump: impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.3., in order to prevent wear and corrosion, sewage pumps generally use better wear resistance, corrosion resistance, mechanical seal and O ring as the seal of water pumps, and clean water pump without strict consideration.To sum up, we can get a very good understanding of why not water pump sewage problems -- characteristics of channel and the impeller and other key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used sewage.
