What are the conditions for the series and parallel connection of the pumps?
Water pumps in series require equal flow, and the latter should be able to withstand the pressure of two pumps and.The parallel pump requires the pump with equal lift head, and the outlet pipe in parallel shall be chosen according to the flow rate of two pumps.
1, pump series, the two pumps must start and stop at the same time in order to normal operation.2 when the pump is connected in parallel, the two pumps must be equipped with check valve at the same time to operate normally.3, of course, in the election of the pump, should meet the requirements of upstairs said.
Parallel pumps: the pump is required to lift the same. This effect is to increase traffic.Pumps in series: requirements are similar to the flow of water pumps. This allows you to increase the total head and recommend adding small pressure tanks during the series connection.
