WARNING!
The pump can break through the base or slide off it
– Ensure that the base is horizontal, flat and perma‐
nently load-bearing.
Capacity too low
Vibrations can disturb the liquid end valves.
–
Do not allow the base to vibrate.
WARNING!
Motor may overheat
If the necessary cooling air supply is not guaranteed,
the motor may overheat. In an area at risk from explo‐
sion, it could trigger an explosion.
– Maintain sufficient clearance between the air
intake opening and the walls. The distance should
be greater than 1/4 of the diameter of the air intake
opening.
– The fan must not suck in the exhaust air from other
devices.
WARNING!
Danger with high pressure
Feed chemicals at pressures above 100 bar can seri‐
ously injure people standing nearby in the event of a
discharge-side leak - particularly if energy stores, such
as pulsation dampers, are used.
– Use appropriate guard panels to shield the dis‐
charge-side components if necessary.
