The Valcor solenoid operated metering pumps are positive displacement devices where the effects of fluid pressure, density and viscosity are minimized, as the flow rate is almost entirely dependent on the volume displaced by the piston during each stroke and on the number of strokes per unit time. These pumps thus provide flow accuracies greater than those of conventional pumps or flow valves (read more)
