3.1 Placement
Install RUVAC WH/WHU pumps on a flat, horizontal surface (2° max. tilt).
If the pump is not levelled, lubricant may enter the pumping chamber from
the gear chambers.
The pump’s ambient temperature should be between 10 °C und 40 °C (WH
4400/7000) or 50 °C (WH 2500). Lower temperatures hamper run-up; higher
ones shorten the lubricant change intervals and may lead to greater wear.
Moreover, the pump attains its thermal operating limit faster.
In combination with the maximum allowable differential pressure higher
temperatures can even damage the pump.
Install the pumps only in indoor rooms. Sudden cooling of the pump cas-
ing during operation will damage the pump.
The RUVAC pumps are designed to be functional at altitudes up to 1000
m above sea level. Operation at higher altitudes is permissible in consider-
ation of reduced operating limits (derating). Please consult Leybold in this
case.
Secure the pump.
Use the bores at the bottom of the rubber elements.
When bolting the feet down, make certain that there is no stress or twist
on the pump casing. Stress on the pump can change the close tolerances
between the impellers and the pump casing and may result in damage to
the pump (use washers to equalise).
Since compensation elements must be attached to the flanges on the
intake and discharge sides, the screws for attachment of the feet must
always be fitted and tightened.
Notice safety information 0.1.
Use screws 4 x M 12.
