I have fitted a self-priming pump and I have to start it up. Does the pump's body have to be filled with water?

Yes, when it’s first started the pump must always be filled with water and the procedure below has to be followed:

  1. Undo the hexagonal cap on top of the pump’s body;
  2. use a funnel to fill the pump with water until it overflows;
  3. screw the hexagonal cap back on until it’s blocked, this prevents air to seep in.

Which is the maximum temperature for the self-priming pump's fluids?

Usually the maximum temperature of the fluid in a self-priming pump should not exceed 45°C.
Some models can handle fluids at higher temperatures. If the requirements differ from the standard please contact our sales network or our Technical Customer Service.
