What are the advantages and disadvantages of self-priming wastewater pumps?

Some self-priming pumps can handle solids up to 3 inches, so handling solids can be counted as one of the key benefits. Compared to a submersible pump, the other advantage we encounter is; While the pump is out of the pit, the liquid can continue to pump. Although pumps are advantageous in many respects, they also have their own disadvantages. One of the disadvantages of self-priming pumps, perhaps even the most important, is that they are prone to some air leaks. The suction line of a self-priming pump is always below atmospheric pressure. Therefore, air leakage is possible. Self-priming pumps need to be refilled after the first priming.

What are the things to consider when using a self-priming wastewater pump?

Each pump has its own user manual, which contains information not only for operating the machine but also for extending its life.
We have gathered the items to be considered when using a self-priming wastewater pump under a few headings;
• Before using the pump, always test for leaks at the connector, suction line or pump seals. Leakage that may occur in these areas will render the pump inefficient.
• The length and diameter of the self-priming pump hose or pump pipe is another important point. The length and diameter of the pump’s hose or pipe can affect the suction of the pump. The longer these hoses and pipes are, the greater the suction power.
• It is an important detail for a self-priming pump to be close to the water source, so that friction is minimized.
• Self-priming pumps should be primed before first use.
• Freezing should be prevented in places where work is done in cold weather. If the water freezes, it expands, which can cause the stem to break.
