How do I check the direction of rotation of a MATRIX multistage pump?

  1. Start the pump for a for a few moments;
  2. Position yourself looking at the pump on the fan side (rear);
  3. Check if the fan is turning clockwise according to the sticker arrow on the fan cover.

WARNING: the correct direction of rotation for a MATRIX 18 pump is anticlockwise.

Is the PRA peripheral pump self-priming?

No, it’s a peripheral pump with an impeller that can operate when there is air or gas.

I own/bought a PRA pump, how do I carry out the first start-up properly?

The first start-up requires the following operations:

  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 cap back on until it’s blocked, this prevents air to seep in.

Please make sure that there is nothing blocking the dip tube’s foot valve. Once these steps have been carried out, turn the switch on and off two or three times in order to check the pump’s operating conditions and its direction of rotation. Then start its continuous operation and gradually open the delivery gate. Please always refer to user and maintenance manual.
