Venturi vacuum pump Q-VDF series

liquidssuctionadjustable

The Q-VDF Series Adjustable Vacuum Pumps operate using the Venturi Principle to move air or liquid from one end of the pump (vacuum port) to the other end (output release). The straight-through, compact design offers high vacuum flow rates up to 120 SCFM (3400 LPM) and high vacuum levels up to 25 in. Hg (847mbar).   Developed for extremely contaminated/dusty environments, such as foundry, refractory, and bagging operations, Q-VDF pumps do not clog, lose suction, or require a vacuum filter. Virtually all contaminants can easily pass through the unit without obstruction. Q-VDF pumps are field-adjustable allowing you to regulate the vacuum flow and vacuum level to meet specific application requirements. This maximizes energy efficiency by consuming only the compressed air necessary to do the job.   Principles of Operation  The variable performance of the Q-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. • Non-clogging, straight-through design • High input-to-output performance ratio • Field adjustable per application • No moving parts • Maintenance free operation/no downtime • Safe operation • No electricity at pump
