Series and Parallel Pump Test Rig (Multistage) VSLIC-TM05

Two identical pumps operated in parallel approximately double the discharge while preserving the same head. Likewise, when two identical pumps should connected in series. The discharge rate should be same as that from one pump but the head is approximately doubled. It is often more economical to for two pumps in series or parallel operation rather then a single larger one which may be underutilized for much of the time. In the former arrangement one pump may be switched off when demand is low, thereby operating at the higher efficiency and also enabling maintenance to be done on the idle unit.
