In this application, when transferring the gravel/water mix long distances, the booster pumps are used to keep pushing the mix along through the line.  The customer purchased an additional gearbox as a spare, as they have been extremely happy with one that they have had in operation for over 30 years.

Reduction Gearbox Used in Centrifugal Pump

Centrifugal pumps are most commonly used for pumping low viscosity fluids, such as water, solvents, oils, acids, organics etc.  Cotta’s engineering team designed and manufactured this reduction gearbox that will be used in a large centrifugal pump. First-piece inspection was conducted on every machining sequence, starting at the source to support our zero-defect policy.  After assembly, and testing of the gearbox in Cotta’s state-of-the-art testing facility, the unit was painted in Cotta’s inhouse paint booth, packed, then shipped out to the customer.
