Transportation and Storage
Roots pumps are heavy machines (> 70 kg) made of
cast iron and thus should only be lifted using suitable
lifting equipment tied to the crane eye (8/3) provided for
this purpose.
Before transporting the pump always drain
out the oil from of the bearing spaces (see
Section 5.2). Screw the oil-drain plug with
its gasket back in and wipe any oil droplets
off from the casing.
It will not be required to drain out the oil
from the shaft seal housing (oiler).
The pump should be transported and
stored in a horizontal position (5
°
max. tilt
with respect to its longitudinal axis).
Otherwise there is the danger that oil from
the bearing chambers may enter the pump
chamber, even before the pump is filled with
oil for the first time.
The pump must only be moved and
installed in its horizontal orientation.
Otherwise the oil in the shaft seal housing
(oiler) may spill out.
When shelving the pump for a longer period
of time, the oil should be drained out and
you should seal off the flanges of the pump
with a piece of foil or the cardboard discs
initially supplied with the pump using the
collars. Place a bag with desiccant in the
pump chamber, if required.
The area of the motor (fan and slits at the
flange of the motor) must be protected
against dust and dripping water.
