How to Select the Correct Pump for Your Pump Station

Pump stations are often referred to as simplex duplex triplex quadraplex and so forth depending on the number of pumps. This allows a pump station to "scale up" its pumping rate to meet higher pumping requirements. If one pump is unable to handle the inflow to the pump station another pump can kick on to increase the pumping rate.
