  • Parallel operation KSB Pumps, Valves and Service KSB

    Parallel operation, or parallel pumping, of two centrifugal pumps is a mode which allows pump operation to be controlled by starting or stopping one of the two pumps.. If two centrifugal pumps I and II are operated in parallel, the flow rate QI+II is the sum of the flow rates of the individual pumps

  • How To Operate Centrifugal Pumps In Series Or Parallel

    Putting your centrifugal pumps in series, or connected along a single line, will let you add the head from each together and meet your high head, low flow system requirements. This is because the fluid pressure increases as the continuous flow passes through each pump, much like how a multi-stage pump works. For example, if two of the same pumps are in series, the combined performance curve

  • Pumps in Parallel or Serial Engineering ToolBox

    Centrifugal pumps in parallel are used to overcome larger volume flows than one pump can handle alone. for two identical pumps in parallel and the head kept constant the flow rate doubles compared to a single pump as indicated with point 2; Note! In practice the combined head and volume flow moves along the system curve as indicated from 1 to 3. point 3 is where the system operates with both

  • Understanding pump curves #3: centrifugal pumps in parallel

    Centrifugal pumps are frequently operated in parallel to achieve higher system flows, to enhance system flexibility or to provide greater pump redundancy and hence better system availability. For very large projects, limited availability of sufficiently large pumps or limits on driver size or electrical starting current may dictate the use of multiple pumps. There are traps for the unwary

  • Parallel or Series Pump Operation by

    Parallel, or series operation A parallel operation is one where two, or more, pumps are connected such that the pumps take their suction flow from a common source and discharge into a common header or tank. The total flow rate in the system is the total of the flow rates of the individual pumps which can be different from each other. Pumps in parallel should have stable or continuously rising

  • Parallel Pumps: Reliability & Efficiency Issues WaterWorld

    Parallel Pumps: Reliability & Efficiency Issues. Parallel pump installations, where two or more pumps take suction from a common manifold and discharge into a common header, are very common in many industries, including the Municipal Water and Wastewater markets. Nov 1st, 2008. By Allan R. Budris . Parallel pump installations, where two or more pumps take suction from a common manifold and

  • What You Need to Know About Parallel Pump Operation

    Learn what you need to know about parallel pump operation in this article from Jim Elsey. Operating pumps in parallel has advantages, but also risks. If the system is not designed for pumps to operate at the same time, both will experience issues.

  • Limitations & Benefits of Operating Two Pumps

    When Pumps are operating in Series, the effects of Pump failure is more serious than Pumps which are set to operate in Parallel. If the failed pump is Pump-B, then Pump-A would suddenly have a serious System Resistance causing its flowrate to be very low or even zero. This resistance might be caused by the system or by the stationary Pump-B.

    15/07/2018· Pump series & parallel operation PUMPS IN SERIES Centrifugal pumps are connected in series If the discharge of one pump is connected to the suction side of second pump.

  • What You Need to Know About Parallel Pump Operation

    Learn what you need to know about parallel pump operation in this article from Jim Elsey. Operating pumps in parallel has advantages, but also risks. If the system is not designed for pumps to operate at the same time, both will experience issues.

  • The Basics of Parallel Pump Control Pumps & Systems

    Many of today’s pumps are installed to operate under variable flow conditions, so understanding the concept of parallel pump control is a must. First, it is critical to know how parallel pumps will operate upon installation. The idea behind parallel connected pumps is the ability to add or subtract flow capacity and/or provide redundancy.

  • Centrifugal Pumps in Parallel Engineers Edge

    Centrifugal Pumps in Parallel Since the inlet and the outlet of each pump shown in Figure 11 are at identical points in the system, each pump must produce the same pump head. The total flow rate in the system, however, is the sum of the individual flow rates for each pump.

  • Series operation KSB

    Series operation means that pumps are connected and started one after another, i. e. in series. This type of operation has many advantages over parallel operation in cases where the system characteristic curve Hsys(Q) is steep and the pump characteristic curve HI+II(Q) is flat (see Characteristic curve).The addition of the head values of pumps operating in series is better suited to the steep

  • Centrifugal Pumps Engineering Library

    In addition, centrifugal pumps provide a high volumetric flow rate with a relatively low pressure. In order to increase the volumetric flow rate in a system or to compensate for large flow resistances, centrifugal pumps are often used in parallel or in series. Figure 11 depicts two identical centrifugal pumps operating at the same speed in

  • Multiple Centrifugal Pumps In Series And Parallel

    For many young process engineers the concept of multiple centrifugal pumps in series or parallel is often confusing. Today's blog entry tries to explain the concept of centrifugal pumps in series and parallel. First of all let us understand what it means by pumps in series and parallel. When we say multiple pumps are in series, it means that the discharge of the first pump provides the suction
