How to prime a centrifugal pump before starting it up

How to fill the pump, and how to determine if it is full? :(

Open the inlet valve and the exhaust valve; once liquid comes out of the exhaust valve, it can be considered that it is filled

Install the drain plug on the upper part of the pump body; water will flow out as long as this is in place

There are mainly two types: one is to fill water by using a mounting bottom valve. Otherwise, the water pump will not be able to pump water. When a centrifugal pump does not discharge water after starting, it is often due to air remaining in the pump and the pump not being filled with water. The foot valve is a one-way valve installed at the inlet of the water inlet pipe. The disadvantage of this approach is that it results in significant head loss due to the foot valve, which affects the efficiency of the water pump ; Another method is filling the tank using a bottom valve; the greatest advantage of this approach is energy savings, with potential savings of 10% to 15% compared to pump stations equipped with bottom valves. Simply open the drain plug at the top of the pump, and water will flow out.

Open the inlet valve; generally, the exhaust pipeline branches off from the outlet pipeline. By opening the exhaust pipeline, the tank is considered full once oil starts to flow out of it~~~

Can this still be done if the pump transports toxic substances?

If transporting toxic media, I don’t think centrifugal pumps are generally used, as their sealing isn’t very good; it’s better to choose diaphragm pumps instead
