4.5.3
Checking the flow direction
NOTICE!
Risk of damage due to frictional heat!
The frictional heat that develops can cause damage to the pump
components.
— A rotary lobe pump with rubber-coated rotors should not run
dry, i.e. without pumped medium,
for longer than 15 sec-
onds
at a normal speed under any circumstances.
—
The rotary lobe pump must not be put into operation
during the following function test.
— Ensure that all valves and shut-off devices are closed.
The flow direction on Börger rotary lobe pumps can be reversed,
and is defined by the direction of rotation of the drive.
After establishing the electrical connections, check if the flow direc-
tion of the rotary lobe pump is correct by means of the direction of
rotation of the drive shaft.
Example: Standard drive with two-stage helical gear unit
