Q: Are your pumps protected against dry running?

A: 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.

Q: How can I get trained on CNBM products?

A: 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.

Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.
