Which is the fluid's maximum allowed temperature for the CD centrifugal pump?
For the standard version the temperature range is 60°C – 90°C according to the model.
The versions that are equipped with different mechanical seals can pump liquids up to 120°C.
Please check the pump’s technical documentation and instruction manual for the maximum allowed temperature limits according to the version.
Regarding the CD 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.
What is the noise level of the CD centrifugal pump?
The noise level of the CD centrifugal pump is <70 dB at a one metre distance
How do I check the CD centrifugal pump's direction of rotation?
How do I carry out the CD centrifugal pump's first start-up properly?
The first start-up requires the following operations:
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.
When should a CD centrifugal pump be chosen as an alternative to a CDX(L) centrifugal pump?
The CD centrifugal pump is more suitable for applications that need special care for the hygiene of the environment where the pump is fitted. The motor part is almost entirely made of AISI 304 stainless steel, this makes the external cleaning of the pump and of the motor easier.
