Q: Are CNBM pumps available in DIY stores?
A: Yes, currently, we’re available for DIY stores all over the world.
Q: Where do I have to send pumps for service?

Q: Are your pumps acid-proofed?
A: To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.
Q: Can your pumps mount Eff.1 motors
A: Currently, only on request though this will shortly be a CNBM standard.
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.
