A centrifugal pump by its principle is not self priming because of its limited ability
to transport air. The Hendor priming chamber overcomes this problem and adds a
self priming feature to a standard horizontal pump. The priming chamber is initially
filled with solution. Priming time will depend on length/diameter of suction pipe.
After the inital filling of the chamber, next time, the pump will automatically reprime.
The maximum pump flowrate will be reduced by approx 20% compared to the
published flow curve. The pressure/head will not be affected.
