The self-priming ability of Portable Transfer Pump/Handheld Pump is one of its important performance indicators.
First of all, the self-priming ability depends on the design principle of the pump. Generally speaking, its self-priming process is to suck the liquid into the pump cavity through the partial vacuum formed in the pump. For Portable Transfer Pump/Handheld Pump, the structure and design of the impeller have a significant impact on the self-priming ability. If the impeller is reasonably designed and can more effectively form a vacuum and generate sufficient suction, then the self-priming ability will be relatively strong.
Under different working conditions, there are obvious differences in self-priming height and speed. Under ideal working conditions, if the conveying medium is a clean, low-viscosity liquid (such as clean water), the self-priming speed of the pump may be relatively fast. This is because low-viscosity liquids are more easily sucked into the pump cavity and will not generate too much resistance in the pump. At this time, the self-priming height may also reach the design upper limit of the pump. However, when the working conditions change, such as when conveying high-viscosity liquids (such as oils), the self-priming speed will slow down significantly due to the poor fluidity of the liquid. High-viscosity liquids require the pump to have a stronger suction force to overcome its internal viscous resistance, and the self-priming height will also be affected to a certain extent, which may be lower than the self-priming height in low-viscosity liquids.
In addition, when the pump is used at different altitudes, changes in atmospheric pressure will also affect the self-priming ability. In high-altitude areas, the atmospheric pressure is lower, and the difficulty of the pump to form a vacuum will increase, and the self-priming height and speed will be limited. On the contrary, in low-altitude areas, it is relatively easier to achieve a better self-priming effect. Moreover, if there are problems such as air leakage in the inlet pipeline of the pump, the self-priming ability will be greatly reduced. In short, the self-priming ability of the Portable Transfer Pump/Handheld Pump is affected by many factors. In practical applications, it is necessary to reasonably select and use the pump according to different working conditions, and take appropriate measures to optimize its self-priming performance to ensure that it can work efficiently and stably.
