Checking / Maintenance
3.3 Cleaning the Dirt Trap
Located in the intake port is a wire mesh sieve acting as
a dirt trap (8/10) for foreign objects. This sieve must be
kept clean in order to avoid any throttling of the pump.
To clean the dirt trap remove it from the intake and clean
it in a vessel using a solvent. Then thoroughly dry it with
compressed air. If the dirt trap is faulty you must replace
it.
Adapt the cleaning intervals according to
the requirements. If large quantities of abra-
sive materials are involved you should
install a dust filter in the intake line.
3.4 Removing and Inserting
the Internal Demister
Simple maintenance on the side of the pump using
Maintenance Kit 1
Required tools:
Allan keys 4 and 8 mm
The internal demister has been installed in a resiliant
frame. When it has clogged it will lift itself up periodically
at high intake pressures in order to equalise the resulting
pressure difference.
The increased noise level at high intake pressure is thus
a sign for a clogged internal demister.
Depending on the operating conditions the internal demi-
ster will have to be cleaned regularly or it must be
exchanged. Cleaning must be performed using a suitable
solvent.
Switch the pump off and drain out the oil (in accordance
with Section 3.2).
In order to collect the remaining oil in the oil box we
recommend that you lift the pump up slightly at the side
of the motor.
Unscrew the four hex. socket screws (8/3) of the oil box.
Pull the oil box (8/2) out to the front.
Remove the gasket (8/11) of the oil box.
Use a pair of pliers to pull the spring (8/5) out to the front.
Detach the holding frame (8/8) and the internal demister
(8/9).
Clean all parts and check them for perfect condition and
replace them as required.
Reassemble in the reverse order.
Make sure to fit the gasket for the oil box
(8/11) with the flat side in the groove, see
item 12 in Fig. 8.
Torque for the hex. socket screws (8/3) is
5.5 Nm.
