Mechanical Speed Variation and Inverter Drive
The Mechanical Speed Variation and Inverter Drive Flexible Impeller pumps are indentifiable by their mechanical speed variation, which adjusts the output speed of the gearbox. The series is also characterized by their dry run protection and come supplied with trolley and inverter control panel.
This series is made up of the VA and INV. The VA pump provides a flow range that is ideal for applications that don’t require accurate flow control. The INV Series has a much more accurate flow control. This is achieved through an affixed inverter panel that is pre-wired and calibrated to ensure the speed of the motor is between the minimum and maximum speed points.
Speed adjustments to the VA & INV Series cannot be adjusted whilst the pump is in operation.
