The pump head is se cu red in the hou sing (4) by 5 cap screws (14, 22). It ba si cal ly com pri ses a flan g e (44) with worm (25) and the pump ele ment with is fa ste ned on top of the flan g e. Both con trol- ((29) and feed plun ger (31) of pump ele ment are dri ven via an ec cen tric (28, 50, 51 and 47, 48, 49) run ning in ball bea rings. The plun gers are po si -ti ve ly con trol led in the ec cen trics thus sei zin

a risk of air fin ding its ways into the pump and main li nes.
To en su re trou ble-free functio ning the pump it self should
be bled by ope ra ting it for a pe riod wit hout back pres su re.
As soon as the lu bri cant is disch ar ged free of air bub bles
from  pres su re  con nec tion (P),  the  feed  li nes  can  be
