It's normally done using a pump that can exceed the maximum pressure/flow requirements of the system by approximately 20-25%. An inverter, a variable speed device, will control the pump so that it can supply flow/pressure as required by the system.

Based upon the clients' requirements for minimum and maximum water velocity in the pipe.
