Selection method of self - priming sewage pump

Self-priming sewage pump products in the sewage pump series and self-priming pump products belong to a commonly used pump products, it and self-priming and sewage function so called self-priming sewage pump, many users of self-priming sewage pump products Of the technical information to master less, the following Shanghai weihu sewage pump manufacturers introduced under the suction sewage pump on the selection method.

First to confirm the good medium is what medium, whether corrosive containing corrosive selection of stainless steel material is competent, weihu self-contained sewage pump products corrosion-resistant materials are only a variety of stainless steel material, if the stainless steel material can not be used to re-election without seal Self-priming pumps can be used instead.

And then confirm the medium inside the solid particle diameter and fiber length, respectively, usually the diameter of the solid particles is 10% of the pump diameter, for example, the pump diameter is 100mm then the maximum diameter of the pump through the diameter of 10mm, fiber length of the pump diameter of 60% Length, such as 100mm caliber Yantai self-priming sewage pump through the fiber length of 60mm long, if beyond the above range, then we recommend the use of open impeller weihu self-suction sewage pump better.

In addition, the self-priming suction pump self-priming height is also extremely critical, the most commonly used Yantai self-priming sewage pump is ZW self-suction non-clogging sewage pump and ZWL direct Yantai self-priming sewage pump, Height is within 5 meters, 5 meters altitude when the self-priming time in 3-5 minutes or so, the only difference is that they are ZW with coupling type, ZWL are non-coupling type, ZWL machine occupies Small size and compact structure.If the self-priming height of 5 meters and self-priming time is very short recommended the use of vacuum suction pump or the fastest suction pump.

And then is to choose the right flow, head, flow head if you feel the need for large flow head is relatively small We recommend the use of small self-priming pump products, the small self-priming pump can also be used as a sewage, because the impeller are The use of open-type impeller structure, and that self-priming sewage pump flow head is too small can also choose my company's high-flow self-priming pump products
