Belt systems for pumps : What should be the life expectation target for a belt driving a pump ? One says that the belt cannot show any sign of weakness until the maintenance technician starts to forget when he has done the last change. Even if this sounds like a trivial approach, this is the challenge that Hutchinson is taking up in the design of its Flexonic® and Poly V belts for pump applications : make the drive efficient and durable. From the mines with heavy duty constraints to the industrial small and very efficient pump, Hutchinson is at your side to advise on the best solution.
