Many users in the process of selection of self-suction sewage pump, due to self-priming sewage pump product technology to grasp less, so I do not know how to choose a good quality pump, in view of this situation Now introduce to you Xiaobian self-suction sewage pump selection method. Self-suction sewage pump selection method 1, first confirm that the medium is a good medium of delivery, whether corrosive containing corrosive use of stainless steel can be competent, self-priming sewage pump products currently corrosion-resistant material is only a variety of stainless steel, If stainless steel can not be used, please elect non-sealed self-priming pump can replace it. 2, and then confirm the medium inside the solid particle diameter and fiber length, respectively, what is the size, usually solid particle diameter is 10% of the size of the pump diameter, such as the pump diameter is 100mm then the maximum diameter of the pump through the particle diameter of 10mm, the fiber length of the pump diameter 60% of the length, for example, 100mm diameter self-priming sewage pump through the fiber length of 60mm long, if beyond the scope of the above then we recommend the use of Bo Yu's open impeller self-priming sewage pump better. 3, In addition self-priming sewage pump self-priming height is also very crucial, the most commonly used self-priming sewage pump is ZW self-priming non-clogging sewage pump and ZWL direct-coupled self-priming sewage pump, these two self-priming sewage pump self-priming height Are within 5 meters, self-priming time of 5 meters height in about 3-5 minutes, the only difference is that they are ZW Belt Coupling, ZWL Belong to no coupling, ZWL machine area Compact structure. If the self-priming height higher than 5 meters and self-priming time is very short Recommended Bo Yu vacuum self-priming pump or the fastest self-priming pump. 4, and then is to choose the right flow, head, flow head If you feel the need for large flow head lift is relatively small We recommend the use of Bo Yu small self-priming pump products, the small self-priming pump can also be used as sewage, because the impeller Are using open impeller structure, and that the self-priming sewage pump head lift so small can also choose my company's large flow self-priming pump products.
