Diaphragm Pump Orientation Significantly Improves Efficiency

Diaphragms in pumps and valves isolate liquid from mechanical components. Diaphragm pumps and valves work well in applications with pressures that cause recirculation in centrifugal pumps and excessive wear in positive displacement pumps and valves. Evidence suggests that the orientation of the diaphragm—horizontal or vertical—makes a significant difference to its effectiveness.
