Parallel use of piston pumps and the issue of outlet dampers
Thread Content
Dear sea friends, the flow rate of the plunger pump is 12 m3/h, with an outlet pressure of 306 bar. If two identical pumps are used in parallel and the phase difference is adjusted to reduce the impact of pulsations on the flow rate, will there be any problems? Additionally, I would like recommendations for reliable domestic manufacturers of dampers that can be used in this application scenario. Thank you!

However, the pump is driven by an asynchronous motor, and the speed of the motor cannot be set to whatever value is desired; it depends on the motor itself and the load. Moreover, there is a reduction gear mechanism between the motor and the pump. Therefore, unless there is a targeted structure to control the phase, an ideal phase shift condition cannot be achieved; it’s actually more practical to use a buffer tank at the outlet.
