5. FAQ

1> Can your pumps mount Eff.1 motors

Currently, only on request though this will shortly be a CNBM standard.

2> Are your pumps protected against dry running?

No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

3> How can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.
