CHEMICAL DOSING VOLUME CONTROL BY BACK STOP STROKE LIMITING
LOST MOTION PUMP limited suction stroke, by "Back Stop " stroke length volume control. Pumps based on this design principle are usually small, have PTFE diaphragm, and with design pressure below 1000 psi.
The lost motion method of flow control has a small disadvantage, that the discharge stroke begins with a shock unless the pump is set for full stroke.. The shock may be so severe that it has to be intercepted by a multiport flow through damper.
