Case Study: Solving NPSH Issues for an Industrial Customer

An industrial customer was experiencing monthly centrifugal pump failures due to cavitation caused by a non-vented boiler return stream. The centrifugal pump required higher NPSHa than the return stream could provide. Wood Equipment Company proposed and installed an MTH Regenerative Turbine Pump with a flow inducer to replace the existing centrifugal unit. The MTH unit allowed the pump to hit the required curve for the boiler size while keeping NPSHr under 1 PSI. This is a big win for the customer, who will save a lot of maintenance and pump replacement costs because of the change in pump type.
