ANVER Q-VDF Series
Adjustable Vacuum Pumps
The Q-VDF Series of adjustable air powered vacuum pumps provide a combination
of high vacuum flow rates of up to 120 SCFM, and vacuum levels of up to 25"
Hg. Because of their straight-through design, the Q-VDF Series is recommended
for handling porous materials and ideal for operation in contaminated
situations.
This unit is noted for its ability to pass virtually all contaminants through the unit without
obstruction.
Q-VDF pumps can be used to pick and place materials as diverse as
concrete block, and packaging materials that are coated with
fine powder. They are typically used in air driven industrial
vacuum cleaners to remove liquid and/or solid mixtures from sump
areas. Q-VDF pumps are user-adjustable and eliminate the need for additional
regulation of air lines to remotely vary the levels of vacuum or flow that
is required.
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.
