What kind of liquid can I pump with the CDA centrifugal pump?

It’s designed to be used with clean water, non-aggressive liquids for residential and industrial use. It’s also certified for pumping drinking water. Contact our Technical Customer Service for information on specific application areas.

How do I carry out the CDA centrifugal pump's 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.

Regarding the CDA centrifugal pump, can I extend the power cord without causing technical problems or affecting the warranty?

Yes, anyhow this operation has to be carried out by a specialised technician or at an authorised EBARA Service Centre. This avoids improper connections that can adversely affect the pump’s correct operation and/or the safety of the installation.

Which are the applications the CDA centrifugal pump can be used for?

It’s designed to be used for clean water handling and for food use, for domestic system pressure boosting, washing systems, industrial applications and to be fitted into equipment that uses non-aggressive liquids.

How do I check the pump's direction of rotation?

  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.

What is the noise level of the CDA centrifugal pump?

The noise level of the CDA centrifugal pump is <70 dB at a one metre distance

What is the difference between a single impeller and twin impeller pump?

A twin impeller version’s performance is better in terms of head, while the flow rate remains the same.
