WARNING!
Motor may overheat
If the necessary cooling air supply is not guaran‐
teed, the motor may overheat. In an area at risk
from explosion, 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.
CAUTION!
Danger from incorrectly operated or inadequately
maintained pumps
Danger can arise from a poorly accessible pump
due to incorrect operation and poor maintenance.
– Ensure that the pump is accessible at all times.
– Adhere to the maintenance intervals.
WARNING!
Risk of burns with hot feed chemicals
If hot feed chemicals can heat the liquid ends
above the permissible surface temperatures, per‐
sons can suffer burns from them.
– Consider attaching a "Hot surface" label to the
liquid end or ...
– fitting a guard plate.
Position the pump so that control elements, such as the stroke
length adjustment knob, the indicating dial A or the oil inspection
window, are accessible.
Make sure that there is enough space to carry out an oil change
(vent screws, oil drainage plugs, oil trough ...).
1 Discharge valve
2 Dosing head
3 Suction valve
Ensure there is sufficient free space (f) around the dosing head as
well as the suction and discharge valve so that maintenance and
repair work can be carried out on these components.
Capacity too low
The liquid end valves cannot close correctly if they
are not upright.
–
Ensure that the discharge valve is upright.
