Each time the pump is turned off, the priming chamber retains a volume of liquid. When the pump is re-started, it pumps the en-trapped liquid out of the priming chamber, creating a vacuum in its place. Atmospheric pressure then forces liquid from the tank or sump up the suction hose or pipe to the pump, completing the prime.
Pump Priming, self priming pumps & priming chamber
A priming chamber is a tank that holds enough liquid to keep the pump submerged until pumping action can be initiated. Self-priming pumps usually incorporate some form of priming chamber in the pump casing that must be filled with liquid in order to “self prime” the pump.

Priming chambers add a self-priming feature to a standard horizontal pump. A centrifugal pump by its principle is not self-priming, because of its limited ability to transport air. The priming chamber is initially filled with solution. The priming time depends on length/diameter of suction pipe.

A priming chamber in its simplest form is a tank with an outlet at the bottom that is level with the pump suction nozzle and directly connected to it. An inlet located at the top of the tank connects with the
manually priming the pump at every start-up, ANTICO has developed moulded polypropylene priming chambers. A priming chamber is a reservoir which maintains positive head on the pump. In case of suction lift applications, the priming chamber generates enough vacuum so that the liquid rises and enters the chamber thus continuing to keep it full.
Centrifugal pumps may require a priming chamber as an aux-iliary means of lifting liquid from below the pump centerline to the pump inlet or from the liquid surface over a tank wall. The answer to this requirement is this line of easy to use and install priming chambers.
Priming Chambers are for use with horizontal style mechanical seal or magnetic drive centrifugal pumps when the liquid is below the pump centerline. Verify solution compatibility with materials of construction of priming chamber. Read operating instructions and instructions supplied with chemicals to be used.

Priming chambers are designed for high flow applications where typical priming valves are restrictive. However, better options are now available.
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.
