Looking for recommendations for high-self-priming pumps
Thread Content
Our pool requires a self-priming pump with a suction lift of >6.5 meters. Do any of you know which manufacturers can provide such a high suction lift? What are the main technologies?
The conditions of the medium and the required parameters must also be clear; in some cases, a self-priming centrifugal pump is not necessarily necessary, as there are many engineering solutions that can address the issue
It becomes more difficult when the tank is open. The limit for vacuum level is Okpa; atmospheric pressure is around 100 kPa. Theoretically, the maximum height from which a pump can draw water at room temperature is less than 10 meters. Additionally, factors such as water temperature, atmospheric pressure, resistance in the inlet pipes, and the fact that the vacuum level cannot reach Okpa make it quite difficult for the pump to draw water from a height of 6.5 meters or more
Suction lift > 6.5 meters. Where does this figure come from? How deep is your pool, and is the pump placed right next to it?
Is it just water? The centrifugal pump with siphon tank is installed next to the pool. Or use a WFB self-priming control pump, which can draw water up to about 6 meters.
The Liaoning Grete vacuum diaphragm high self-priming pump can be used
My family has a powerful self-priming pump equipped with a auxiliary impeller; it has a self-priming height of 6–9 meters. It features excellent self-priming capabilities, with quick priming – the priming process is completed within 3 seconds. When the pump is in operation, the self-priming impeller generates a strong negative pressure, which allows the gas in the suction pipe to be expelled outward through the exhaust port, thereby enabling stable priming in a short time. The pump is dedicated to water treatment research and development, and its advanced water treatment design ensures energy efficiency and high performance
