Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L) 95/140
Spread some clean oil of the same type as used to lubricate the
pump over the different parts, in particular the inner lip of the
oil seal, the bushings and vanes.
If the oil seal has the dust-block lip, 2/3 fill the area between the
two lips with ISOFLEX TOPAS NB5051 grease.
CAUTION!
Do not allow the grease into the area of the circumferential spring.
Lock without forcing the nuts on the four tie-rods (44) connecting
the parts of the pump block. Before locking, check that all parts
are touching as required.
Before putting the springs and shutters of the discharge valves
back in, pour a little oil into the stators through the holes in the
valves.
CAUTION!
Before hooking the recall spring to the anti-suckback command bar, make sure
you have put the bar all the way into the sleeve of the rotary feedthrough to
avoid bending the tapered part of the bar.
NOTE
On DS102 1Ph, DS202 1Ph and DS302 1Ph pumps, fit the joint on the motor
shaft after careful removal of grease from the surfaces and application of
LOCTITE 242.
