DETAILS
A true dry-prime pump, our self-priming system eliminates the need for water to prime the pump and is engineered to prevent product carryover. The result is an environmentally safe self-priming system for solid industrial or municipal waste or any light slurry applications. Also available in silent pack configurations that are ideal for municipal bypass and construction dewatering installations.
The vacuum priming system is used to pull water into the pump, which then allows the pump to start. It does this by creating a vacuum that extends from the top of the impeller right down to the water level of the reservoir from which the liquid is being pumped. As the vacuum removes air molecules from the pump, water is pushed up into it.
At the highest point of the priming system, you will find a priming valve. And while there are many types of priming valves, the most commonly used type uses a float to turn off the vacuum system once the water gets high enough to raise the float. This helps to ensure that water does not get inside the vacuum pump. When a sufficient amount of liquid has been pulled into the centrifugal pump, a sensor alerts the pump operator that the pump has been primed and that it is now safe to turn on the water pump drive motor
