2/18/2024 0 Comments Duplex sewage ejector pump system![]() The other reason for using a duplex pump configuration is redundancy. This drastically reduces wear on the pumps, and it also means that one pump can be pulled out for maintenance, which leads into the next benefit of a duplex configuration. This basically just means that the pumps take turns pumping each time the lift station runs. With two pumps in the pump station, the pumps can cycle between starts. It also applies to the wear on the pumps. Although two pumps will likely cost more than a single large pump, the improvements to pumping efficiency without VFDs makes that margin much slimmer because of the cost of the VFD components and the increased power draw every time the large pump runs.Įfficiency in a duplex configuration applies to more than just power consumption and meeting multiple flow scenarios. One pump can be used to handle the daily flow requirements, and if the peak flow is ever experienced, both pumps can be used to reach that pumping rate. This is the basic concept of a duplex pump configuration. The other option is to meet the peak flow with two pumps. Electrical controls with variable frequency drives, or VFDs, could increase the efficiency to some degree, but this would add cost and complexity. If only one pump was used, the pump would need to be very large to meet the peak flow requirements, and it would be extremely inefficient at pumping the lower, “daily” flow requirements. While designing for a peak flow requirement makes sense, it is, by definition, in extreme excess of the daily flow rates a lift station must pump. This design requirement is to prevent ever experiencing an overflow scenario. In wastewater and sewer applications, the “peak flow” needs to be able to be pumped by the lift station even if it never happens. This requirement is something called “peaking factor,” and it describes the maximum flow rate that could potentially ever need to be pumped. The efficiency reasons have to do with a typical design requirement for pumping wastewater. The best answer is that there are efficiency and redundancy reasons for using two pumps over one. The first question you might have about a duplex pump station is why two pumps are necessary. Duplex configurations are often the best engineering solution for wastewater applications. ![]() Pump stations can also be designed as simplex, triplex, and up to pentaplex configurations, all depending on how many pumps are required to meet the flow requirements. A duplex configuration means that there are two pumps in the system. The duplex pump configuration is one of the most common configurations in a pump station design, and it provides owners with several benefits.
