Abstract

In this work we have systematically studied the behavior of solenoid pumps (SMP) as a function of flow rate and flow resistance. Using a new, economic, and miniature control unit, we achieved improvements of the systems versatility, transportability, and pressure robustness. A further important improvement with respect to pressure resistance was achieved when a flexible pumping tube was inserted between the solenoid pump and the flow resistance acting as a pressure reservoir and pulsation damper. The experimental data were compared with two pressure pulse models for SMP, which were developed during this work and which were well-suited to describe the SMP operation.
