Stainless steel gear pump is a pump and motor Siamese, and at the same time submerged work under the pump products, compared with ordinary gear pump or asphalt pump, stainless steel gear pump clearly has the following advantages: 1. Compact structure, Small plot in the air. The stainless steel pump can be directly installed in the sump due to its submerged operation. It is not necessary to build a special pump room to install the pump and machine, thus saving a lot of land and construction costs. 2. Installation maintenance lunch. Small stainless steel gear pump can be free devices, large stainless steel gear pump usually equipped with automatic coupling installation can stop automatic device, installation and maintenance quite convenient. 3. Continuous operation for a long time. Stainless steel gear pump pump and motor coaxial, short shafts, rotating parts light weight, so the bearing to accept the load (radial) is relatively small, longer life expectancy than the ordinary pump. 4. There is no cavitation damage and irrigation water and other issues. Especially after the point to the operator brought a lot of convenience. But everything is split into two parts. The most critical issue with stainless steel pumps is usability issues. Stainless steel pumps are used under liquid conditions. The medium to be dispensed is a mixture of liquids that contain solid materials. Pumps and motors Close to the pump; vertical arrangement of the pump, rotating parts weight and water pressure in the same direction with the impeller. These problems make stainless steel gear pump in the seal, the motor bearing capacity, bearing arrangement and selection of the request is higher than the average sewage pump.
