Before installing the self-priming pump, a suitable concrete foundation should be made according to the foundation size of the self-priming pump, and the anchor bolts should be pre-embedded during the process of making the concrete foundation. Making concrete foundation refers to large self-priming pump products. Small self-priming pumps do not need to make concrete foundation. 2. Before installing the self-priming pump, you should carefully check whether the bolts of the self-priming pump are loose and whether there are any foreign objects falling into the pump body to avoid damaging the impeller when the self-priming pump is running. 3. Place the self-priming pump on the concrete foundation, place an isolation pad between the bottom plate and the foundation, and adjust the level of the isolation pad to align the level of the pump, and tighten the bolts after adjustment. 4. The water suction pipe and outlet pipe of the self-priming pump cannot be supported by the water pump. Instead, separate brackets are needed to support the inlet and outlet pipes, and the diameter of the inlet and outlet pipes should match the diameter of the self-priming pump. In particular, the inlet pipe cannot become larger. If it becomes larger, it will affect the self-priming height of the self-priming pump. If the inlet pipe of the self-priming pump is reduced during installation, the outlet pipe must also be reduced. We recommend that it is better to configure the corresponding pipes according to the factory standard caliber. 5. When the self-priming pump has a dust cover at the factory inlet and outlet, you should remove the dust cover and connect it to the pipeline. It should be noted that if you are using a self-priming pump product that can suck out water faster, the outlet pipeline must be vertically upward for 1 meter before turning. Otherwise, the water in the pump body will be easily drained during the self-priming process. 6. For the convenience of maintenance and safe use, a regulating valve should be installed on each of the inlet and outlet pipes of the self-priming pump, and a pressure gauge should be installed between the outlet valve and the pump to ensure that the self-priming pump is used within the rated flow and head range, so that the self-priming pump can operate normally and extend the service life of the self-priming pump. 7. Before starting the self-priming pump, you should turn the pump shaft and fill the pump cavity with liquid at the same time, so that the liquid fills the pump cavity for the purpose of exhausting. Check whether there is any leakage in the pump. The impeller should have no friction sound or stuck phenomenon. If there is friction sound or stuck phenomenon, the pump should be disassembled and the specific cause should be checked and solved.
