FAQ

Question?
What does the ‘BUBE’ code in the type number CR16-50 A-F-A-BUBE signify?

The ‘BUBE’ code specifies the shaft seal configuration. It stands for a balanced seal with Silicon Carbide rotating and stationary parts (SiC/SiC) and EPDM rubber parts, which is suitable for a wide range of water and non-corrosive liquid applications.

Question?
Is the 5.5 kW motor suitable for variable speed operation with a frequency drive (VFD)?

Yes, this standard Grundfos MG induction motor is designed to be compatible with a Variable Frequency Drive (VFD). This allows for precise control of the pump’s performance and significant energy savings in variable demand systems.

Question?
What are the flange specifications for the inlet and outlet connections?

The ‘F’ in the type number indicates DIN standard flanges. For a CR16 pump, these are typically DN50 flanges rated for PN16, although it is always best to verify the exact dimensions before installation.
