How does a VDF pump work?The variable performance of the VDF pump is achieved by increasing the annular gap between the venturi nozzle and the diffuser. Rotating the diffuser section counter-clockwise will increase the opening, allowing more compressed air to flow through the unit and increasing both the vacuum flow and the vacuum level. The result is a variable vacuum pump that can be adjusted to meet an application's exact requirements.
