How to make the self-priming pump flow head work stably
Self-priming stabilization method 1. The bottom valve is installed in the suction port of the suction pipe of the self-priming pump, and the bottom valve cannot be sucked up normally. It is recommended to use a suitable bottom valve. 2. Since the inlet pipe is too long to exceed the self-priming capacity of the self-priming pump, if the pipe in which the inlet pipe is submerged in the water is more than 1 m, it is recommended to shorten the length of the pipe in the water to reduce the...
Comparison of self-priming pump with centrifugal pump, submersible pump and submerged pump
The self-priming pump principle uses a unique patented impeller and separation disc to force the gas-liquid separation to complete the inhalation process. Its shape, size, weight and efficiency are similar to those of pipeline pumps. Vertical self-priming pumps do not require auxiliary equipment such as bottom valves, vacuum valves, and gas separators. It does not need to be filled when the normal production starts, and has strong self-priming ability. It can replace the currently widely used...
