This electro-mechanical controller for adjusting pump stroke is designed to replace the current manual stroke adjustment system on positive displacement piston pumps (Fig. 1). This affordable system could be retrofitted on any existing piston pump for real-time adjustment of the pump stroke, which makes it possible to change the flow rate of a piston pump automatically from zero to pump’s full capacity. The system can be controlled using a pre-described position sequences or real-time sensor-based commands. In addition, the system can adjust pump stroke manually, using a pre-calibrated electric dial.
