V1.0 41
S Contact manometer (installation position)
Q1 Diaphragm on dosing head side
Q2 Diaphragm on oil side/pump side
3q Intermediate disk
4q Sealing rings
5q Covering rings
6q Clamping sleeves
Caution
The paraffin oil between the diaphragms (Q) is connected via the clamping sleeves
(6q) to the contact manometer (S) in order to fill and activate the diaphragm brea-
kage signal. It is able to pass between the diaphragms through the slits in the clam-
ping sleeves and the slits in the intermediate disk.
The clamping sleeves (6q) must therefore be installed in such a way that the slits in
the clamping sleeve face the slits in the intermediate disk (3q) (see above).
9.7.3 Fitting the dosing head
• Fit the dosing head and tighten the dosing head screws crosswise using a torque
wrench.
Note
Refer to the “Start-up” section for subsequent start-up.
9.7.4 Filling the double diaphragm with separating agent
Note
After a diaphragm has broken, the ball check must be cleaned before forng filled
with separating agent. Only clean the ball check after a diaphragm breakage!
After the diaphragm has been replaced for a pump with a double diaphragm, refill the
separating agent between the diaphragm:
1. Set the stroke adjustment button of the pump to 0 %.
2. Open the filling screw (1u) and deaeration screw (2u) by one rotation.
3. Connect the filling hose to the nipple of the filling screw (1u) and, using the dosing
syringe inject the correct amount of paraffin oil that is specified in the table below.
4. Close filling screw (1u), but leave the deaeration screw (2u) open.
5. Start up the pump with a system counterpressure and 40 % stroke adjustment.
