Considerations when buying KCB gear pump
KCB gear pump to measure the quality of the performance , power size is not important, unit efficiency is the key. In the case of the same head, the same flow , high- efficiency power small , that is a good performance. KCB gear pump has a maximum lift Tagging traffic flow and rated head on the market are most KCB gear pump flow rate marked the highest lift , some manufacturers KCB gear pump labeling is outrageous , such as the common 90w and 120w copper head growth pump, standard power 80w ( maximum lift 10 meters ) and 120w ( maximum lift 13 meters ) .
Some businesses in order to achieve good sales , into 100w ( maximum lift 12-15 meters ) and 150w ( maximum lift 15-20 meters ) , traffic is scary high . There are self-priming KCB gear pump , suction lift is 10 meters theory , because KCB gear pump NPSH ( head manufacturing roughness caused by the phenomenon of water vapor ) in the presence of an effective self-priming gear pump suction KCB 8 -8.5 m. But businesses in order to attract customers attention to these parameters standard was beyond imagination. So before you buy KCB gear pump sellers would like to know more about the actual parameters KCB gear pump , such as the actual head and actual flow , in order to avoid trouble. Booster pump at work , the maximum flow rate is zero when the lift to the highest lift when the flow is zero. According to changes in the flow and head conditions for each point , we can draw the KCB gear pump curve , which is characteristic of KCB gear pump performance curves . KCB gear pump selection to be based on the scene to decide, such as: pipeline length , diameter size , number of elbows, water heater capacity, type heaters , nozzle out of water , and so on . Especially in confined water heaters , because of its special unit , the amount of water required to use a slightly larger KCB gear pump, a small flow KCB gear pump effect is difficult to play .
Pressurization KCB gear pump is not installed on the end of the story , the cause of low water pressure , there are many , such as the typical aging pipes , especially galvanized pipe, will gradually rust after years of use , resulting in blockage caused water pipes to reduce ; also 90 degree elbow too much water can also cause a decrease in the low pressure causes like these , KCB gear pump installed after the effect is very obvious.
Booster has a feature to keep up with the flow when the pipe KCB gear pump KCB gear pump flow or exceed the flow of pressurized effect is not obvious. So before buy KCB gear pump to troubleshoot the cause of low water pressure , not blindly buy KCB gear pump . To purchase , we recommend consulting an experienced plumber or looking to do business staff . Staff benefits to businesses that case KCB gear pump booster effect is not ideal can justifiably require businesses to exchange or return.
