Performance

The catalog curves give the flow–head relationship according to the air inlet pressure and air consumption. In this prototype only the catalog end values are marked; intermediate curves will be added with test data.

The dashed line joins the end points; it is not an actual curve.

Working principle

Two diaphragms are connected to each other by a common shaft. The air valve directs compressed air alternately into the diaphragm chambers; while one diaphragm pushes the fluid, the other one draws suction. The valve changes direction at the end of the stroke.

Animated explanation

Dry-run resistantNo heating or wear occurs when the line runs empty.
Safe stop against back pressureStops when the discharge line is closed and resumes pumping when it is opened.
Suitable for explosive atmospheresContains no electric motor and no electrical connection.
Simple constructionContains no mechanical seal, rotor or impeller; maintenance needs are low.
