2.2.4Functional description, delivery unit

The heart of the delivery unit is the DEVELOPAN® metering diaphragm (2). It hermetically seals the delivery chamber of the liquid end (4) and produces a displacement in the liquid end. The end disc (5) made of chemically resistant plastic together with safety diaphragm (13) separates the drive housing from the delivery unit and protects the drive from corrosion in the event of the diaphragm failing. Delivery is based on the interaction between intake valve (1) and head valve (3) of the same design together with the diaphragm movement. The valve balls can be supported with springs for metering viscous media.

The connection dimensions of valves and liquid ends of the same size but with different materials are identical. These parts can be interchanged as required.

Materials and dimensions are specified in Section 3, Technical data.
