13.4 Liquid separator
The liquid separator is mounted on the
discharge connection. Its functions consists of
separating the discharged operating liquid form
the pumped gases/vapors. Part of this
separated operating liquid can be fed back to
the pump-motor unit via the operating-liquid
port. The rest is drained off and replaced with
fresh operating liquid.
Operation with a liquid separator and operating
water return is the operating mode
recommended for the pump-motor unit.
The procedure for mounting the liquid
separator on the pump-motor unit is shown in
Fig. 20, Pg. 47, and Fig. 21, Pg. 48. Here the
following applies:
1)
Remove the plug at the top and bottom
on the liquid separator.
2) Screw the hose nipple into the holes on
the liquid separator. Use commercially
available liquid sealant (e.g. Loctite)
when doing so.
 Top hole:
Angled hose nipple.
 Bottom hole:
Straight hose nipple.
For L-BV7 2BV7 060 and 2BV7 061:
The premounted reducer on the liquid
separator is required. Therefore:
 Remove the reducer from the liquid
separator.
 Seal off thread. Use commercially
available liquid sealant (e.g. Loctite)
when doing so.
 Screw the reducer into the liquid
separator again.
For L-BV7 2BV7 070 and 2BV7 071:
The premounted reducer on the liquid
separator is not required. Therefore:
 Remove the reducer from the liquid
separator and dispose of it.
3) Screw the hose nipple into the hole
provided on the pump-motor unit. Use
commercially available liquid sealant
(e.g. Loctite) when doing so.
 Operating-liquid port:
Angled hose nipple, directed toward
the front.
 Connection for cavitation protection:
Angled hose nipple, directed upward.
4) Mount the "T" hose nipple on the angled
hose nipple on the operating-liquid port
with the hose clamp.
5) Place the liquid separator on the
discharge connection and tighten it by
hand. Use commercially available liquid
sealant (e.g. Loctite) when doing so.
6) Mount the hose for returning the
operating liquid (see arrow) with hose
clamps.
 On the liquid separator:
Mount the hose on the lower hose
nipple.
 On the pump-motor unit:
Mount the hose on the side
connection of the "T" hose nipple
(operating-liquid port).
7) Mount the cavitation-protection hose
(see arrow) with hose clamps.
 On the liquid separator:
Mount the hose on the upper hose
nipple.
 On the pump-motor unit:
Mount the hose on the hose nipple of
the cavitation protection connection.

separator.
