A slow rate pumping system which includes a discharge line to receive a discharge flow of displacement fluid from a high rate pumper, a return line off of the discharge line to receive a return flow of displacement fluid, a slow rate diversion pumping line off of the discharge line for supplying a diversion flow of displacement fluid downhole, a return valve to control the return flow, and a diversion valve to control the downhole flow. A method of supplying a slow rate flow which includes receiving a main pumping flow through a return line at a pumping pressure, producing a differential pressure between the pumping pressure and a downhole pressure matching a differential setpoint, diverting a slow rate flow of fluid from the main flow using a diversion line off the return line prior to the return valve, and maintaining the differential pressure.
