8.4 Priming kit
8.4.1 Priming pump
The priming tank is used for suction lift installations and serves to keep the
body of the pump and the inlet pipe full of water, even if the base valve is leaking. Each pump must have its own independent
priming tank, placed at a higher level than the pump. The tank must be connected to a water source for adding water and
keeping it full. The diameter of the connecting pipe to the pump depends on the use class. The recirculation return pipe can be
connected to the tank which must also have an overflow outlet. A level switch automatically activates the service pump if the
level of the tank drops and is not topped up. The hydraulic connections must be made by the fitter.
